and if the address of the lamp point is the same as the address code on the same address bit in the addressing address, the lamp point displays according to the display rule in the addressing instruction.
Wherein, the display rule can be preset manually. And if the address code on the same address bit in the address and the addressing address of the lamp point is different, the lamp point is not displayed according to the preset display rule. For example, it is assumed that the display rule is that the color displayed by the lamp is red. If the address code on the first bit of the address of the lamp point is the same as the address code on the first bit of the addressing address, the color displayed by the lamp point is red; if the address code on the second bit of the address of the light point is different from the address code on the second bit of the addressed address, the light point is not displayed, or is displayed in green. It should be noted that the above is only an example, and the content of the display rule is not specifically limited, and when the address of the lamp point is different from the address code on the same address bit in the address, the lamp point is not displayed according to the preset display rule, and how to display the lamp point is not specifically limited.
Step S303, determining the number of times of the currently sent addressing instruction, and recording the number of times as M.
Step S304, if the lamp point is displayed according to the display rule, the address code of the Mth address bit of the lamp point is the same as the address code of the Mth address bit in the current addressing address.
Step S305, if the light point is not displayed according to the display rule, the address code of the mth address bit of the light point is opposite to the address code of the mth address bit in the current address.

It should be noted that steps S304-S305 are specific implementation processes of "analyzing the address of the light point according to the preset rule and the captured image of the light point" in step S103 in fig. 1.
For example, suppose that the number of bits of the address of the light point is 2, the address of the chip one is 10, and the address of the chip two is 01, the display rule is that the color displayed by the light point is red. The controller sends an addressing instruction of A +01+ M (A is an addressing identification bit, M is a display rule) for the first time, the lamp point corresponding to the chip I is not displayed, the lamp point corresponding to the chip II is displayed in red, the image of each lamp point is captured by the image capturing device, the number of times of the currently sent addressing instruction is 1, the application software analyzes that the address code on the 1 st bit of the address of the lamp point corresponding to the chip I is 0 and the address code on the 1 st bit of the address of the lamp point corresponding to the chip II is 1 according to the preset rule and the captured image of the lamp point; the controller sends an addressing instruction A +10+ M for the second time, the lamp point corresponding to the chip I displays red, the lamp point corresponding to the chip II does not display, the image of each lamp point is captured by the image capturing device, the number of times of the sent addressing instruction is 2, the application software analyzes that the address code on the 2 nd bit of the address of the lamp point corresponding to the chip I is 1 and the address code on the 2 nd bit of the address of the lamp point corresponding to the chip II is 0 according to the preset rule and the captured image of the lamp point. Therefore, the controller only needs to send the addressing instruction for 2 times, the addresses of the lamp points corresponding to the chip I and the chip II can be determined completely, the address of the lamp point corresponding to the chip I is 10, and the address of the lamp point corresponding to the chip II is 01. It should be noted that the above is only an example, and the number of bits of the lamp point address and the display rule are not specifically limited.
According to the embodiment of the invention, the addressing instruction is sent to the LED lamp, the image of the lamp point is captured through the camera device, and whether the lamp point is displayed according to the display rule in the addressing instruction is analyzed according to the preset rule and the captured image of the lamp point, so that the address of the lamp point on the LED lamp can be determined quickly and accurately.
It should be understood that, the sequence numbers of the steps in the foregoing embodiments do not imply an execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present invention.
