[0045] Examples:
[0046] Such as Figure 1 to Figure 7 Shown is a real-time road condition video image of a certain road section in Xi’an. The sampling frequency of the video is 25 frames per second, the video image size is 720×288, and the size of each block is 8×6, so each frame of video image is divided into 90× 48 blocks,
[0047] The selected threshold A is 48×20;
[0048] The selected threshold B is 48×20;
[0049] The selected threshold C is 4;
[0050] The selected threshold D is 55;
[0051] Follow the above method to sequentially process the 339th to 355th frames.
