The video projection of the LED light array is obtained by controlling the LED lights on each bus.

[0104] During the video playback process, there are color changes. Among them, the color characteristics of the target are relatively stable and unchanged during the movement process, and it has quite good adaptability and persistence to the rotation, deformation, and size changes of non-rigid objects. To enhance the adaptability of the tracking method to the changes in landscape lighting, the RGB color space is converted to the HSV color space. Assume that the position parameter of the i-th particle is X i , and the target center is X a . Then the target color histogram distribution is:

[0105]

[0106] Among them, represents the target color histogram; u represents the color histogram bar index; N represents the total number of pixels in the target area; K represents the kernel function; δ represents the impulse function; b(X i ) represents the bar in the color histogram at X i ; h represents the range of the target area; C represents the normalization coefficient.

[0107] By obtaining the target color histogram, the stability of the tracking algorithm is further improved, and more stable video images are obtained, which are finally presented in the form of landscape lighting.

[0108] The beneficial effects of the above technical solution are as follows: The lighting controller outputs video images through Ethernet. The lighting controller packs the RGB image data into UDP data packets according to the set data format and transmits the data to the sub-control unit via Ethernet. The transmission is sent to the LED light array in the form of UDP broadcast. The sub-control unit will grab the UDP broadcast packet from the Ethernet bus, parse and extract the RGB data from the grabbed UDP broadcast packet, and the extracted RGB data is used to control the LED lights on each bus. By controlling the LED lights on each bus, the video playback of the LED light array is obtained. The sub-control unit will not immediately control the lighting display after receiving the video image, but will execute the lighting control according to the RGB image data only after receiving the display synchronization command from the lighting controller. Therefore, the lighting controller only needs to send a display synchronization command to all sub-control units after all the data of a frame of video image is transmitted to ensure that each light of the LED light array is lit simultaneously, avoiding the situation that the display effect of the video picture is affected by the inconsistent lighting time of each light.

Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalent technologies, the present invention is also intended to include these changes and modifications.
