Identity recognition method and system based on gait features

The invention relates to an identity recognition method and system based on gait features, and belongs to the technical field of identity recognition. The method comprises the following steps: acquiring original images under different visual angles, inputting the original images into a target detection model, and determining the position of a to-be-identified pedestrian; segmenting the original image through a pedestrian segmentation model to obtain to-be-recognized pedestrian contours under various visual angles; inputting the to-be-recognized pedestrian contours in each view angle into a classification model to obtain classification results of the to-be-recognized pedestrian contours in each view angle; performing weighted stacking on the identity probabilities of the pedestrians belonging to the same known identity in the classification results of the different visual angles to obtain the final identity probability that the pedestrian to be recognized is the pedestrian with the known identity; the pedestri
