Abstract

The invention discloses a gate passing system based on depth data. The gate passing system comprises a data acquisition module, a data alignment module, a pedestrian positioning module, a height detection module, a distance detection module and a data storage module. Wherein the data acquisition module is used for data depth acquisition, the data alignment module is used for aligning an RGB color image and depth data, and the pedestrian positioning module is used for identifying a color picture acquired by a depth camera through a YOLOv3 target detection algorithm, framing pedestrians and storing the position information of a frame; the height detection module is used for collecting height data of pedestrians; the distance detection module is used for calculating the distance between pedestrians; and the data storage module directly stores all the collected and detected data into a database system for retention and later evidence collection. By means of the system, the height can be calculated to distinguish adults from children, meanwhile, the distance between front and back pedestrians is measured, continuous passing persons are recognized, and more intelligent gate passing detection is achieved.

Description

technical field [0001] The invention relates to the technical field of urban rail transit, in particular to a gate passing system based on depth data. Background technique [0002] With the development of my country's economy, the population has gradually increased. Taking subways and high-speed rails is the first choice for most people to travel. Among them, the subway has a high density of people. During the rush hour, the flow of people reaches the highest value. Management creates a greater burden. [0003] The turnstile system is an important facility to control the speed of pedestrians. When the density of pedestrians is high, the turnstiles are prone to problems such as reduced recognition accuracy and inability to recognize continuous passers-by, which makes it difficult to control the problem of ticket evasion. At the same time, due to the inability to distinguish between adults and accompanying children in the crowd, in the case of a large flow of people, it will b...
