Problems solved by technology
Although this method is fast, there are the following problems: First, although it is possible to judge whether there is a target missed detection or a non-target false detection by judging the quantitative relationship between the detected frame and the marked frame (when the number of detected frames is greater than the number of marked frames, non-target Target misdetection, when the number of detected frames is less than the number of labeled frames, target missed detection occurs), but it is impossible to determine which target is missed or which non-target is falsely detected; second, the detection frame is not always the same as The label box with the largest overlapping area corresponds, and it is not rigorous to use the overlapping area as the corresponding label

The invention relates to an evaluation method and device of a target detection algorithm, computer equipment and a storage medium. The method comprises the following steps: marking all n objects in the to-be-detected image; obtaining n annotation boxes, wherein n is a positive integer; carrying out target detection on the to-be-detected image; obtaining initial detection results, wherein if the target is detected when the target detection is carried out on the to-be-detected image, the initial detection result comprises a detection frame; carrying out target detection on a missing image obtained by deleting a part of or all of n objects in the to-be-detected image, wherein if the target is detected when the target detection is carried out on the missing image, the missing detection resultcomprises a detection frame; and evaluating the target detection algorithm according to the initial detection result and / or the missing detection result, so that the target detection algorithm can beaccurately evaluated.
Description
technical field [0001] The present application relates to the technical field of object detection, in particular to an evaluation method, device, computer equipment and storage medium of an object detection algorithm. Background technique [0002] Target detection is a technology for detecting targets from images through target detection algorithms. The accuracy of target detection algorithms directly affects the detection effect of targets. Therefore, how to intelligently and accurately evaluate the quality of a target detection algorithm has always been a challenge for those skilled in the art. The focus of the research, and the performance evaluation of the target detection algorithm is the evaluation of the detection effect of the target. Therefore, the target detection algorithm can be evaluated by evaluating the detection effect. [0003] In the traditional method, when evaluating the accuracy of multi-target detection, it is necessary to manually mark multiple targets...
