The invention discloses a target identification and tracking method and system. The target identification and tracking method comprises the following steps: acquiring video stream data of a tracking target motion area, wherein the video stream data comprises multiple frames of images; selecting a target area in the previous frame of image; calculating characteristic value probability distributionof the target area; selecting a target estimation position from the current frame image; selecting a target estimation area according to the target estimation position; calculating characteristic value probability distribution of the target estimation area; calculating the similarity between the probability distribution of the characteristic values of the target area and the probability distribution of the characteristic values of the target estimation area; and determining the real position of the target according to the similarity. According to the target identification and tracking method,the similarity between the probability distribution of the characteristic values of the target area and the probability distribution of the characteristic values of the target estimation area is calculated, and the real position of the target is determined according to the similarity, and the target position can be accurately determined in target recognition and tracking.
Description
technical field [0001] The invention relates to the field of target recognition, in particular to a method and system for target recognition and tracking. Background technique [0002] Today's target recognition and tracking technology plays a very important role in the field of computer vision. At present, there are many popular recognition and tracking algorithms implemented in FPGA, such as centroid tracking algorithm, three-frame difference method, optical flow method, etc. When these algorithms encounter external interference, the target will be lost and lost, and the target cannot be accurately tracked. [0003] In some survey environments that need to liberate humans, such as space survey survey vehicles, smart home nanny robots, missile-guided vision systems, and mine robots that conduct surveys and rescues inside mines, these are all places that need to liberate humans. is particularly important.
