The present application relates to a target detection method, system, device, storage medium and computer equipment. The method includes: obtaining the current frame in the video frame sequence and the preceding key frame corresponding to the current frame; determining the preceding key frame and the current frame The optical flow feature map and the optical flow map between them; when the current frame is determined to be a non-key frame according to the optical flow feature map, the key frame features corresponding to the previous key frame are obtained, and the key frame features are affine transformed according to the optical flow map , to obtain the image feature corresponding to the current frame; detect the pixel level of each pixel in the current frame according to the image feature, and obtain the detection result corresponding to the target in the current frame. The solution provided in this application can improve the efficiency of object detection on video.
Description
technical field [0001] The present application relates to the field of computer technology, in particular to a target detection method, system, device, computer-readable storage medium and computer equipment. Background technique [0002] Target detection is one of the hotspots in the field of computer vision research. Computers simulate human visual characteristics through algorithms, and mark target areas in images or videos to achieve target detection. [0003] The existing method of target detection for video requires feature extraction for each frame of the video, and then performs pixel prediction for the video frame based on each extracted image feature, to obtain the detection frame corresponding to the target in each frame, and realize Object detection for video. However, since features are repeatedly extracted for each frame, the computational load is very large and the detection efficiency is low. Contents of the invention [0004] Based on this, it is necessa...
