Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

In practical application, it is found that an individual user, such as the elderly or people with unknown characters, has an operation obstacle in executing terminals such as smart phones. When a business operation needs to be executed by collecting and identifying a digital object identifier, a special application is often required to be opened to start a digital object identifier identification process, and the special application is found in a plurality of applications installed in an execution terminal, which is very inconvenient for users.

The embodiment of the invention provides that the acquisition function and the execution function of the digital object identifier can be separated, the digital object identifier is acquired and identified through the independent acquisition terminal without integrating other application programs, and the execution terminal is triggered to execute the preset operation according to the service execution instruction in a service execution instruction mode. The embodiment of the invention aims to reduce redundant operation of a user, thereby bringing about good use experience.

Referring to fig. 1, a digital object identifier recognition system according to an embodiment of the present invention includes:

the acquisition terminal 110 acquires the digital object identifier by using a camera, identifies a service execution instruction contained in the digital object identifier, and transmits the service execution instruction to the execution terminal 120 by adopting a short-distance wireless communication technology;

the execution terminal 120 receives a service execution instruction from the acquisition terminal based on the short-range wireless communication technology, and triggers and executes a preset operation according to the service execution instruction.

The camera in the acquisition terminal 110 may be a Complementary metal-oxide-semiconductor (CMOS) camera, and specifically may be an ultra-low power consumption CMOS camera, and the power consumption is a μ W-level chip.

The CMOS camera adopts an ultra-low power consumption CMOS image sensor, and can integrate a camera which is always started so as to be used for computer vision application such as gesture induction, intelligent ambient light and proximity induction, tracking, object recognition and the like. The architecture of this sensor is such that the sensor consumes only <2mW of low power consumption at qvga (quarter vga)30 FPS. The resolution of the CMOS camera is 320 × 320 pixels, and a 320 × 320 window mode (which can be read at a maximum frame rate of 60 FPS) and a 2 × 2 monochrome merge mode (maximum frame rate of 120FPS) are supported. Video data is transmitted over a configurable 1-bit, 4-bit or 8-bit interface and supports frame and line synchronization. The sensor integrates a black level calibration circuit, an automatic exposure and gain control loop, a free running oscillator and motion detection circuit, and an interrupt output to reduce host computations and commands to the sensor to optimize system power consumption. The sensor adopts a Chip Scale Package (CSP) or a bare chip, and the size of the sensor is less than 5mm 2.

The execution terminal 120 of the embodiment of the present invention may be an intelligent terminal such as a mobile phone. The collection terminal 110 and the execution terminal 120 both correspond to the same user identifier and can be associated in advance, so that the accuracy and the safety of information transmission are ensured.

Referring to fig. 2, the acquisition terminal according to the embodiment of the present invention may further include: a processor module 210, a bluetooth module 220, and a power module 230.

The processor module 210 specifically executes to identify from the image of the digital object identifier the service execution instructions contained by the digital object identifier. The processor module 210 specifically decodes and decrypts the digital object identifier to obtain the service execution instruction of the digital object identifier.

The processor module 220 of the embodiment of the invention adopts an ARM Cortex M4 processor core, can operate and reduce the power consumption to below 6 muA/MHz, and has the operation frequency as high as 96 MHz.

The bluetooth module 220 enables the collection terminal to establish a communication connection with the execution terminal, so that the collection terminal sends the service execution instruction to the execution terminal.

The power module 230 of the embodiment of the present invention is used to supply power to the camera 200 and the processor module 210. Specifically, a coin-type battery holder can be arranged on the processor module 210 for installing a button battery, and meanwhile, the camera normally-open function can be achieved.

The digital object identifier identification method of the embodiment of the present invention is described below with reference to fig. 3 to 5.

Referring to fig. 3, an embodiment of the present invention provides a digital object identifier identification method, where an execution subject of the method is an acquisition terminal, and the method specifically includes the following steps:

step 310: capturing an image of the digital object identifier with a camera;

step 320: identifying, from the image of the digital object identifier, a service execution instruction contained by the digital object identifier;

step 330: and sending the service execution instruction to an execution terminal by adopting a near field communication technology, wherein the service execution instruction is used for triggering the execution terminal to execute preset operation.

The camera of the embodiment of the invention can be an ultra-low power consumption CMOS camera, wherein the ultra-low power consumption is in a micro watt level. Because the power consumption is very low, the CMOS camera with the ultra-low power consumption can be controlled to be in a normally open acquisition state. Thus, the user can initiate a shot by aiming the camera at the digital object identifier. This enhances the convenience of use for users who are not convenient to operate.

In an optional embodiment of the present invention, the acquisition terminal may set a physical button, and when it is detected that the in-house button is triggered, a camera is started to shoot. At this time, the camera may not need to be kept in a normally open state.

The digital object identifier of the embodiment of the present invention may be a two-dimensional code, a barcode, or an identifier in other forms, which is not specifically limited herein.

In an embodiment of the present invention, before identifying, from the image of the digital object identifier, the service execution instruction included in the digital object identifier, the method further includes:

determining the acquired image of the digital object identifier to be in a YUYV format;

converting the YUYV format into an RGB format;

identifying, from the image in the RGB format, a service execution instruction contained by the digital object identifier.

If the YUYV format is acquired at the beginning, the YUYV format needs to be converted into the RGB format to realize the subsequent image recognition and analysis.

In an alternative embodiment, the digital object identifier image may be initially captured in RGB format.

Referring to fig. 4, an embodiment of the present invention further provides a specific digital object identifier identification scheme, including the following steps:

step 410: carrying out graying processing on the image in the RGB format;

step 420: filtering the grayed image to obtain an identifier effective area;

step 430: performing Hough transform on the identifier valid region to extract features of the digital object identifier;

step 440: and decoding the extracted characteristics of the digital object identifier to obtain a service execution instruction.

The purpose of the graying processing is to reduce interference of color information.

The image of the digital object identifier is filtered in order to filter out non-digital object identifier areas, thereby obtaining an identifier valid area, which is an area that contains the image of the digital object identifier as much as possible. In particular, a median filtering method may be employed to filter the grayed digital object identifier image.

In an optional embodiment, the foreground and background can be extracted from the effective area of the identifier through image binarization, so that the segmentation is more reasonable, and the image is clearer through image morphology.

The hough transform is a feature extraction, and is used to identify features in an object to be found, for example: a line. The principle of Hough transform is that a curve given in an original image space is changed into a point in a parameter space through the duality of lines and points, so that the detection content of the curve given in the original image is changed into peak content in a searching parameter space. Then, the corresponding service execution instruction is obtained by decoding and decrypting the digital object identifier.

In the embodiment of the present invention, the service execution instruction is the content hidden by the digital object identifier, and the content of the service execution instruction differs corresponding to a specific service scenario. For example, the service execution instructions may contain information to be presented. The service execution instructions may be payment instructions, containing corresponding account information. The service execution instruction may be an information acquisition instruction, and includes an identifier of information to be acquired, such as address information. The specific content of the service execution instruction is not described herein again.

The near field communication technology provided by the embodiment of the invention can realize the establishment of the near field communication connection between the acquisition terminal and the execution terminal. The short-range wireless communication technology includes ZigBee, bluetooth, or WiFi, and is not particularly limited herein.

When transmitting the execution instruction to the execution terminal, encryption setting may be performed to ensure information security.

step 510: receiving a service execution instruction from an acquisition terminal based on a short-distance wireless communication technology, wherein the service execution instruction is obtained by acquiring an image of the digital object identifier by the acquisition terminal through a camera and identifying the image of the digital object identifier;

step 520: and triggering and executing preset operation according to the service execution instruction.

Through the short-distance wireless communication technology, the execution terminal and the acquisition terminal establish communication connection in advance, so that the instant transmission of the execution instruction can be realized.

The service execution instruction plays a role in triggering, and triggers the execution terminal to execute the preset operation, specifically, the preset operation is executed by a corresponding application in the execution terminal. In this case, the service execution instruction may include a corresponding application identifier to identify a specific application and trigger execution of a preset operation.

In the embodiment of the present invention, the preset operation may be displaying content in the service execution instruction, executing a payment operation, or searching and displaying information according to address information in the service execution instruction, which is not limited herein.
