Abstract

The invention discloses a pedestrian labeling, detecting and gender identifying method based on a vertical overlook angle. The method comprises the following steps: acquiring a video and acquiring a vertical overlook angle image of a video frame based on the video; labeling the vertical overlook angle image based on a video labeling method to obtain a pedestrian rotation whole body frame; constructing a pedestrian track based on the pedestrian rotation whole-body frame, and performing gender attribute labeling on the pedestrian track to obtain a pedestrian rotation whole-body frame with a label; training a pre-constructed pedestrian detection network based on the pedestrian rotation whole body frame to obtain a pedestrian detection model; and training a pre-constructed pedestrian gender identifying network based on the pedestrian rotation whole-body frame with the label to obtain a pedestrian gender identifying model. According to the invention, identity characteristics of pedestrians are not involved under the condition of a vertical overlook angle, and pedestrian privacy can be well protected. The pedestrian marking, detecting and gender identifying method based on the vertical overlook angle can be widely applied to the field of pedestrian detection.

Description

technical field [0001] The invention belongs to the fields of pedestrian data tagging, pedestrian detection, and pedestrian attribute recognition, and in particular relates to a pedestrian tagging, detection and gender recognition method based on a vertical viewing angle. Background technique [0002] With the development of the Internet and artificial intelligence technology, intelligent video surveillance systems are widely used in security monitoring, smart retail and other fields. Among them, the pedestrian counting function is one of the most basic and core functions, so the basic requirement of the intelligent video surveillance system is to output accurate pedestrian counting. In addition, the simple number of entries and exits can no longer meet the growing demand for passenger flow attributes, such as outputting the basic attribute gender of pedestrians. The system based on accurate pedestrian counting and pedestrian gender identification can already output the bas...
