Embodiment Construction
[0053] The flow chart of the method for detecting and tracking based on the circular frame buffer provided by the present invention is described in detail as follows:
[0054] Step S1, set up a circular buffer on the time axis; the circular buffer, assuming that the current frame is m, and the capacity of the buffer is m-n, then the content of the buffer is the video frame data from the nth frame to the mth frame; As the axis advances, a new frame will overwrite the oldest frame of data in the buffer; the buffer supports multiple concurrent target detection and target tracking sharing; the buffer supports random read and write, and supports reading from any frame.
[0055] Step S2, select a system video frame according to a strategy from the continuous frame sequence input in real time and set the frame number; select a system video frame according to strategy X from the continuous frame sequence input in real time, wherein the strategy X can be flexibly formulated, Set the se...
