Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.

The dynamic image playing method provided by the application can be applied to the application environment shown in fig. 1. Wherein the terminal 102 communicates with the server 104 via a network. The server 104 may obtain an image sequence of a dynamic image to be played, where the image sequence may include at least two single-frame images, and then the server 104 may stitch the single-frame images in the image sequence to obtain a corresponding stitched image, and further, the server 104 may send the stitched image to the terminal 102, so that the terminal 102 cuts out each single-frame image from the received stitched image, and draws the single-frame image in a canvas according to a time sequence to play the dynamic image. The terminal 102 may be, but not limited to, various personal computers, notebook computers, smart phones, tablet computers, and portable wearable devices, and the server 104 may be implemented by an independent server or a server cluster formed by a plurality of servers.

In one embodiment, as shown in fig. 2, a method for playing a dynamic image is provided, which is described by taking the method as an example applied to the server in fig. 1, and includes the following steps:

step S202, obtaining an image sequence of a dynamic image to be played, wherein the image sequence comprises at least two single-frame images.

When the dynamic image is played, the multi-frame image is switched, and the image seen by human eyes is continuously dynamic by controlling the switching time or frequency.

In this embodiment, the image sequence is a sequence of moving images, and the image sequence may include at least two single-frame images, and each single-frame image represents an image state.

In this embodiment, the server may draw an image sequence of the dynamic image based on a special effect requirement of a specific service, and the number of single-frame images in the image sequence and the image effect of each single-frame image may be different according to a difference of the specific special effect.

And step S204, splicing the single-frame images in the image sequence to obtain corresponding spliced images.

Wherein, the image is spliced by splicing a plurality of images.

In this embodiment, after acquiring the image sequence, the server may determine the number of images in the acquired image sequence, and based on the image data, splice the single-frame images to obtain a corresponding spliced image.

Specifically, each single frame image in the image sequence may be as shown in (a) or (b) in fig. 3 below, and the stitched image may be as shown in fig. 4.

It can be understood by those skilled in the art that when the stitching is performed, only the multiple frames of images are stitched into one large image, and the image pixels of the single frames of the stitched image are not changed.

And step S206, sending the spliced images to the terminal, so that the terminal cuts out each single-frame image from the received spliced images, draws the single-frame images in the canvas according to the time sequence and plays the dynamic images.

In this embodiment, after acquiring the stitched image, the server may send the stitched image to the terminal, so that the terminal performs subsequent processing.

In this embodiment, the server may send the stitched image to the terminal after receiving the request from the terminal, for example, when the terminal starts an application to trigger playing of the dynamic image, the server may obtain the stitched image from the server and perform subsequent processing. Or, the terminal may obtain the stitched image when starting the application, and perform subsequent processing directly based on the dynamic stitched image when the dynamic image needs to be played subsequently.

In this embodiment, after the terminal acquires the stitched image, each single-frame image may be cut from the stitched image, and the single-frame images are drawn in the canvas according to the time sequence to play the dynamic image.

Specifically, the server cuts down each single frame image from the stitched images according to the time sequence, then draws the single frame image into the canvas, and plays the dynamic images. The specific playing process of the dynamic image can be rendered and drawn by combining the playing frequency, the size of the canvas and the like.

For example, referring to fig. 5, after creating the canvas, a brush object may be obtained by a method "var ctx ═ canvas. getcontext ('2 d')", and then each single frame image in the stitched image is clipped by "ctx. drawimage (image, sx, sy, sfidth, sfight, dx, dy, dfidth, dfight)" and drawn in the canvas. Wherein, the parameter "image" represents the stitched image, and the parameters "sx, sy, sfidth, sfight" represent the slice position and size of the defined source image, i.e. the position and size of the cropped image in the stitched image. The parameter "dx, dy, dWidth, dHeight" indicates the position and size of the clipped single-frame image in the target display position and size, i.e., the position and size displayed into the canvas.

According to the dynamic image playing method, the image sequence of the dynamic image to be played is obtained, the image sequence comprises at least two single-frame images, then the single-frame images in the image sequence are spliced to obtain the corresponding spliced image, the spliced image is further sent to the terminal, the terminal cuts out each single-frame image from the received spliced image, the single-frame image is drawn in a canvas according to the time sequence, and the dynamic image is played. Therefore, the single-frame images can be synthesized into the spliced image according to the actual special effect requirement, when the terminal plays, the single-frame images can be captured from the obtained spliced image and played, and the special effect requirement of animation playing is met. In addition, by cutting the single-frame image from the spliced image and playing the single-frame image, for the terminal, the dynamic image can be played only by drawing the cut single-frame image into the canvas, the update of the DOM number of the browser cannot be triggered, and the expansibility of playing the dynamic image is improved.

In one embodiment, stitching single-frame images in an image sequence to obtain a corresponding stitched image may include: acquiring the number of image lines of a spliced image to be generated and the number of images of single-frame images in an image sequence, wherein the number of the image lines is the number of arrangement lines of the single-frame images in the spliced image to be generated; determining the number of image columns of the spliced image to be generated based on the number of image lines and the number of images; and splicing at least two single-frame images according to the number of image lines and the number of image columns and the acquisition time sequence of the single-frame images in the image sequence to generate a corresponding spliced image.

The image line number refers to the arrangement line number of a single frame image in the stitched image to be generated, and may be a preset value, as shown in fig. 4.

In this embodiment, after acquiring the image sequence, the server may acquire the number of single-frame images in the image sequence and acquire the preset number of image lines of the stitched image to be generated.

In this embodiment, the server may determine the number of columns of the stitched image to be generated according to the number of acquired lines and the number of image lines, for example, the number of image columns may be determined by a division method.

Further, the server can obtain single-frame images from the image sequence according to the number of image lines and the number of image columns and perform splicing to obtain a spliced image.

In this embodiment, when the server performs the splicing, the single-frame images may be sequentially spliced from left to right and from top to bottom according to the acquisition time sequence of the single-frame images acquired by the images in the image sequence, so as to obtain the corresponding spliced images.

In one embodiment, after the server acquires the image sequence, the server may determine the number of single-frame images in the image sequence, and determine whether the number is greater than a preset number value.

In this embodiment, when the server determines that the number of the single-frame images is greater than the preset number value, the images are spliced according to the number of the image lines and the number of the image columns to obtain a spliced image. When the number of the single frame images is less than or equal to the preset number value, a frame image list can be generated based on the acquired image sequence and sent to the terminal, so that the terminal plays the dynamic images based on the frame image list.

In one embodiment, the number of image rows and the number of image columns of the stitched image may also be determined based on the number of single-frame images in the image sequence, for example, the number of image rows and the number of image columns are set to be equal or different to a minimum, so that the length and width dimensions of the generated stitched image do not differ too much.

In the above embodiment, the single-frame images are spliced according to the number of the image lines and the number of the image columns and the acquisition time sequence to obtain the spliced image, so that the accuracy and the integrity of image splicing can be ensured, the possibility of errors is avoided, and the accuracy of playing the subsequent dynamic images is improved.

In one embodiment, stitching at least two single-frame images according to the acquisition time sequence of the single-frame images in the image sequence according to the number of image rows and the number of image columns to generate a corresponding stitched image may include: acquiring a preset line spacing and a preset column spacing of a spliced image to be generated; and splicing at least two single-frame images according to the line spacing, the column spacing, the image line number and the image column number and the acquisition time sequence of the single-frame images in the image sequence to obtain corresponding spliced images.

In this embodiment, when the server performs image stitching, the server may obtain a preset row-to-row distance and a preset column-to-column distance between rows and columns of a stitched image to be generated, and then perform subsequent stitching processing.

Specifically, the server may perform stitching according to the acquisition time sequence of the single-frame images in the image sequence according to the line spacing and the column spacing to obtain the corresponding stitched image.

In the above embodiment, by setting the line spacing and the column spacing and performing the splicing, the subsequent cutting can be performed based on the line spacing and the column spacing when the single-frame image is cut, thereby avoiding the possibility of error in cutting.

In one embodiment, as shown in fig. 6, a method for playing a moving image is provided, which is described by taking the method as an example applied to the terminal in fig. 1, and includes the following steps:

and step S602, receiving a spliced image sent by the server, wherein the spliced image is generated by splicing at least two single-frame images in the image sequence.

The stitched image is as described above, and is not described here again.

In this embodiment, the terminal may acquire the stitched image when the playing of the dynamic image is triggered, and perform subsequent processing operations.

In step S604, a canvas for playing the dynamic image is initialized.

Specifically, the terminal may initialize a canvas of the dynamic image, for example, the terminal may initialize a canvas, cut out single-frame images from the stitched image, and play the dynamic image.

And step S606, cutting out each single frame image from the spliced images in sequence, drawing the single frame images in a canvas according to a time sequence, and playing the dynamic images.

In this embodiment, the terminal may sequentially draw the single frame image obtained by cutting into the initialized canvas, and continuously switch the single frame image drawn into the canvas, so as to implement playing of the dynamic image. For example, referring to fig. 7, when performing image stitching, the server performs stitching in the order from left to right and from top to bottom according to the time sequence 1 to n, and when performing clipping, the server may sequentially clip the single-frame images in the order from left to right and from top to bottom in the stitched image, and sequentially draw the single-frame images in the canvas according to the time sequence to play the moving image.

In one embodiment, sequentially cutting out the single-frame images from the stitched image, and drawing the single-frame images in a canvas according to a time sequence to play a dynamic image may include: acquiring each single-frame image from the spliced images according to the acquisition time sequence of each single-frame image in the spliced images; obtaining the size of a canvas; adjusting the size of the acquired image of each single frame image to the size of the canvas to obtain each single frame image after the image size is adjusted; and drawing each single-frame image after the image size is adjusted in a canvas, and playing the dynamic image.

As previously described, the stitched images are stitched in accordance with the acquisition time sequence of the single frame images.

In this embodiment, when the terminal plays the dynamic image, the terminal may cut and acquire each single frame image from the stitched image according to the acquisition time sequence, and then play the dynamic image.

In this embodiment, the terminal may first obtain the size of the initialized canvas, and then determine whether the image size of the obtained single frame image is consistent with the size of the canvas.

In this embodiment, when the image size of the single frame image is consistent with the size of the canvas, the single frame image obtained by cutting is directly drawn in the canvas for playing the dynamic image, and when the image size of the single frame image is inconsistent with the size of the canvas, the terminal may adjust the image size of the single frame image according to the size of the canvas, so that the image size of the adjusted single frame image is consistent with the size of the canvas.

Further, the terminal can draw the single-frame image with the adjusted image size into a canvas for dynamic image playing.

In one embodiment, sequentially cutting out the single-frame images from the stitched image, and drawing the single-frame images in a canvas according to a time sequence to play a dynamic image may include: initializing a counter, wherein the count value of the counter is equal to the current frame number of the played dynamic image; acquiring a first frame image from the spliced image and drawing the first frame image in a canvas; adding one to the count value of the counter; judging whether the count value of the counter is equal to a preset threshold value or not; and when the count value of the counter is not equal to the preset threshold value, acquiring the next single-frame image from the spliced image according to the acquisition time sequence of each single-frame image in the spliced image, continuously drawing in the canvas, and playing the dynamic image.

In this embodiment, the terminal may initialize a counter and then set the count value to 0.

Further, the terminal may obtain a first frame image, i.e., a first frame image, from the stitched image, and then draw the first frame image in the canvas.

In this embodiment, the terminal may set the count value of the counter to be increased by one, where the count value of the counter is equal to the current frame number of the played dynamic image.

Further, the terminal may determine whether the count value of the counter is equal to a preset threshold value. And the preset threshold value is equal to the number of the single-frame images forming the spliced image.

In this embodiment, when the terminal determines that the count value is smaller than the preset threshold, the terminal may obtain a next single-frame image from the stitched image according to the acquisition time sequence of each single-frame image in the stitched image, and continuously draw the next single-frame image in the canvas for playing the dynamic image.

In this embodiment, when the terminal determines that the count value is equal to the preset threshold, the terminal may determine that the playing of the single frame image in the stitched image is completed, and the terminal may initialize the counter again and restart the playing from the first frame image.

In the above embodiment, the number of the played images is counted by setting the counter, so that the number of the played single-frame images can be accurately tracked, the probability of playing errors is avoided, and the accuracy of playing dynamic images is improved.

In one embodiment, acquiring a next single-frame image from the stitched image according to the acquisition time sequence of each single-frame image in the stitched image, and drawing the next single-frame image in the canvas before playing the dynamic image, may further include: initializing a timer, and judging whether the timing duration of the timer reaches a preset duration or not; and when the timing duration reaches the preset duration, acquiring the next single-frame image from the spliced image according to the acquisition time sequence of each single-frame image in the spliced image, continuously drawing in the canvas, and playing the dynamic image.

In this embodiment, the terminal may further initialize a timer to time the staying time between the frame and the frame single image.

Specifically, the terminal may set a preset duration of the timer, where the preset duration may be determined according to a playing effect of the dynamic tone image.

In this embodiment, after the terminal cuts out the single frame image and draws the single frame image into the canvas, the timer starts to time, and when the timing duration reaches the preset duration, the next single frame image is drawn into the canvas, so as to play the dynamic image.

In this embodiment, after the timer reaches the preset time, the timer may be automatically cleared, and the timing is restarted and the cycle is repeated.

In the above embodiment, by setting the timer and timing the playing time of the single-frame image, it can be ensured that the playing time between the single-frame image and the single-frame image is maintained within the same time, the playing effect of playing the dynamic image is improved, and further the user experience can be improved.

In one embodiment, the method may further include: and uploading at least one of the image sequence and the spliced image to a block chain node for storage.

The blockchain refers to a novel application mode of computer technologies such as distributed data storage, point-to-point transmission, a consensus mechanism, an encryption algorithm and the like. A Block chain (Block chain), which is essentially a decentralized database, is a series of data blocks associated by using a cryptographic method, and each data Block contains information of a batch of network transactions, so as to verify the validity (anti-counterfeiting) of the information and generate a next Block.

Specifically, the blockchain may include a blockchain underlying platform, a platform product service layer, an application service layer, and the like.

In this embodiment, the server may upload and store one or more data in the image sequence and the stitched image in the node of the blockchain, so as to ensure the privacy and security of the data.

In the embodiment, at least one of the image sequence and the spliced image is uploaded to the block chain and stored in the node of the block chain, so that the privacy of data stored in the node of the block chain can be guaranteed, and the security of the data can be improved.
