The invention discloses a pedestrian snapshot optimization method, device, computer equipment and storage medium. The method includes detecting the target object in the video, intercepting snapshots of the target object in different video frames; detecting key point information in each snapshot, filtering out snapshots with complete poses according to the key point information and confirming the identity of the target object in the snapshot Shooting angle, and then classify each snapshot according to the shooting angle to obtain multiple sets of snapshots classified by different angles; then compare the confidence and interception time of all snapshots in each set of snapshots, and select snapshots with confidence from high to low , and the difference between the interception times of adjacent snapshots in the selected snapshots is also greater than the preset time interval, and then sent to the pedestrian database until the number of snapshots sent to the pedestrian database in each group of snapshots reaches the preset number requirement. The invention provides an optimal strategy for pedestrian snapshots, and the selected pedestrian snapshots have the advantage of high recognition accuracy.
Description
Technical field [0001] The present invention relates to the field of image processing, and more particularly to a pedestrian snapshot preferred method, apparatus, computer device, and storage medium. Background technique [0002] The pedestrian snapshot in the video refers to a video recorded video through the camera in the real scene, and the number of pedestrian images collected in the video can be used for computer visual tasks such as pedestrian identification. In the real scene, the angle, height, etc. of the camera is different, the shooting environment is uncontrollable, the pedestrian images obtained under multiple cameras have changed, the image quality is uneven, so most pedestrian identification tasks do not only pass the overall pedestrians Interpretation, you also need to find local constant characteristics, including clothes color, clothes texture, handbag, backpack, etc. [0003] The main practice of currently selecting the pedestrian snapshot from the video is: By...
