specifically, when the height of the tower crane 1 cannot be adjusted continuously, in the third inequality as described above, the width W of the building 2 and the height difference h between the tower crane 1 and the building 2₁-h₂Are all fixed values, and are all fixed values,the third inequality is an upper bound of the angle threshold and is also a fixed value, so that the third inequality can be regarded as a one-dimensional quadratic equation inequality taking the distance L between the tower crane 1 and the building 2 as an independent variable.

Further, with the distance L as an independent variable, the third inequality is sorted to obtain:since the inequality is also a one-dimensional quadratic inequality, andis upwardly open, therefore, in order to ensureLess than 0, it is also necessary to satisfy:andin construction practice, the inequalityGenerally negative and therefore, do not take into accountBut only consider the case ofThe case (1). Order to Substitute it intoIt is possible to obtain:

for example, table 2 shows the distance between tower crane 1 and building 2 calculated from the angle threshold, the width of building 2, and the height difference between tower crane 1 and building 2.

In other words, if the distance L between the tower crane 1 and the building 2 is greater than 97.04 meters, the quality of the image transmitted back by the camera 3 cannot be guaranteed, and at this time, an early warning is required.

According to the technical scheme provided by the embodiment of the disclosure, under the condition that the height of the tower crane cannot be continuously adjusted, the coverage range of the camera device is calculated, early warning can be carried out on buildings which exceed the shooting range of the camera device in a construction area, and the camera device is rearranged according to the coverage range of the camera device.
