Problems solved by technology

[0002] The existing pedestrian detection algorithms are usually very effective for upright pedestrians, but for the detection of inclined and deformed pedestrians, the detected position of the pedestrian is usually inaccurate, and it is difficult to judge the position of the head and feet of the pedestrian based on the position of the detection frame. Location etc.
Since the detection frame is a rectangular bounding frame, if the pedestrian position is not detected accurately, the detection frame will contain more information about the background environment, which will interfere with the next analysis and processing, such as judging the attributes of pedestrians, who the pedestrian is, etc.

Abstract

The present invention provides a pedestrian detection method, device, medium, and electronic equipment. The pedestrian detection method includes: acquiring an original image; determining the positions of the pedestrian's head and feet in the original image; The position of the pedestrian's head and feet, the original image is corrected to obtain the corrected image of the pedestrian in an upright posture; the pedestrian in the corrected image is detected, and framed by a detection frame; according to the corrected The mapping relationship between the image and the original image, mapping the detection frame to the original image, so as to obtain the pedestrian detection area in the original image. The technical solutions of the embodiments of the present invention improve the accuracy of pedestrian detection and ensure that the detected position of pedestrians is more accurate.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular, to a pedestrian detection method, device, medium and electronic equipment. Background technique [0002] The existing pedestrian detection algorithms are usually very effective for upright pedestrians, but for the detection of inclined and deformed pedestrians, the detected position of the pedestrian is usually inaccurate, and it is difficult to judge the position of the head and feet of the pedestrian based on the position of the detection frame. location etc. Since the detection frame is a rectangular bounding frame, if the pedestrian position is not detected accurately, the detection frame will contain more information about the background environment, which will interfere with the next analysis and processing, such as judging the attributes of pedestrians, who the pedestrian is, etc. . [0003] Therefore, how to detect the pedestrians in the distorted image w...
