The invention relates to a method and device for counting passenger flow based on laser ranging. The method includes: S1: obtaining a plurality of effective data packets containing detection point information; generating a background image of the detection channel according to the received multiple effective data packets containing detection point information; S2: when a pedestrian passes through the detection channel, obtaining Multiple contour maps containing pedestrian information; and obtain the contour point data of each contour map according to each contour map and background map; S3: determine the number of pedestrians included in each contour map according to the contour point data of each contour map ; S4: Compare multiple contour maps to obtain the number of pedestrians in a certain period of time. The present invention uses a laser detection device for distance measurement, and the laser detection device obtains the number of pedestrians by using the background map and the contour map, which can avoid the influence of the environment and light on the detection results; in addition, the detection width of the laser detection device can reach 20 meters, which can be applied to large Passenger testing place.
Description
technical field [0001] The invention relates to the technical field of passenger flow statistics, in particular to a method and device for passenger flow statistics based on laser ranging. Background technique [0002] With the continuous development of the national economy and increasingly fierce business competition, it is no longer possible to estimate the passenger flow situation based on experience and guide decision-making based on it; at the same time, transportation hubs, museums, exhibition halls and large-scale Public places such as event sites often have passenger flow congestion during peak hours, and the harm caused by unfavorable monitoring of passenger flow conditions in such emergencies and events is becoming more and more serious. Therefore, it is necessary to analyze the passenger flow, effectively control the passenger flow density, and prevent the occurrence of public safety incidents such as overcrowding and even trampling injuries. [0003] In order to...
