The invention discloses a weak moving target tracking loss reinspection method based on NCC match frame difference. The method includes the following steps of acquiring the video data; performing target tracking of continuous frames of images, and for each frame in the continuous N frames of images of the tracked image, calculating the multidimensional characteristics of the target area to be the normal characteristics and calculating the offset amount of each characteristic with respect to the mean value to be the normal offset amount; when the target in the fth frame of image is lost, intercepting the reference image in the fth frame of image, intercepting the larger image to be matched in the f+kth frame of image, and calculating the cross correlation coefficient matrix; interrupting the area of the set size by taking the position with the largest cross correlation coefficient as the center, obtaining the candidate region by the frame difference method, extracting the multidimensional characteristics of the candidate region, if the deviation between the offset amount of each feature and the normal offset amount is within the set range, taking the candidate region as the target area; otherwise, k automatically increases k, repeating the above processes. The method can prevent the error detection in the traditional method.
