Embodiment Construction

[0015] According to the method of the present invention, vertical laser scanning is performed on two adjacent and parallel sections of the passenger flow channel respectively to obtain the laser scanning data of the two scanning surfaces, and the distance between the two scanning surfaces can be set to approximately As thick as a human body. Then, according to the two pieces of laser scanning data, it is found whether the same pedestrian passes through the two scanning surfaces. Finally, the forward direction of the pedestrian is determined according to the order in which the pedestrian passes through the two scanning surfaces.

[0016] figure 1 is a schematic top view of dual laser scanning according to the present invention.

[0017] Such as figure 1 As shown in FIG. 1 , laser scanning is performed on two cross-sections that are parallel to each other and close to each other in the passenger flow channel, and the distance between the two scanning surfaces is set to be app...

Abstract

The invention provides a pedestrian advancing direction judging method adopting laser scanning, comprising the following steps: respectively carrying out laser scanning on two parallel cross sectionsin the pedestrian advancing direction to obtain a first laser scanning data and a second laser scanning data; and determining the pedestrian advancing direction according to the first laser scanning data and the second laser scanning data. The invention can rapidly judge the pedestrian advancing direction effectively, is not easy to be influenced by an external environment and is convenient to beinstalled and maintained, thereby having good market prospect.

Description

technical field [0001] The invention relates to a method for judging the advancing direction of pedestrians by using laser scanning. Background technique [0002] At present, with the rapid development of the economy, the continuous construction of infrastructure, and the increasingly frequent holding of large-scale organizational activities, the flow of people in densely populated places, such as buses, subways, airports, and railway stations, is increasing. At the same time, the passenger flow information obtained through passenger flow detection is becoming more and more complex, and the amount of information is also increasing. Passenger flow information is an important data to measure the operation status. Through the statistical analysis of passenger flow information, not only can the passenger flow operation status of the traffic area be obtained, but also the detection data can be used to effectively organize operations and schedule work. At the same time, it can al...
