[0069] The present invention will be further described below in conjunction with the drawings and embodiments.
[0070] Such as figure 1 As shown, a visual extraction method of pedestrian multi-dimensional motion features in a traffic environment includes the following steps:
[0071] Step 1: Build a pedestrian movement database;
[0072] Collect videos of pedestrians' various movement poses and road positions in each shooting direction of the depth camera, where the shooting directions include facing the camera directly in front of the camera, front left, front right, side, back, back left, and back right. There are three directions, the postures include walking, running and standing;
[0073] Step 2: Perform image extraction on the video in the pedestrian motion database, and preprocess the extracted image to obtain the pedestrian detection frame of each frame of image, and then extract the pedestrian detection frame image of the same pedestrian in the continuous image frame;
