3D radar scanning-based vehicle congestion detection method, device, and system

Abstract

The embodiment of the present invention provides a 3D radar scanning-based compartment congestion detection method, device, and system, which acquire point cloud data of passengers boarding and disembarking from the 3D radar scanning installed above the compartment doors, and obtain two-dimensional data from the point cloud data. feature data, and then use the pre-trained recognition model to mark the target two-dimensional feature data corresponding to the passenger from the two-dimensional feature data. Track the two-dimensional feature data of each target to obtain the corresponding passenger's walking direction, and then count the number of people getting on and off at the current station according to the walking direction of each passenger, and calculate the number of passengers in the compartment when the train leaves the station. Quantity, send the number of passengers to the next station and display at the next station. Before passengers arrive at the next station, the counted number of passengers in each car is displayed, so that waiting passengers can choose a platform according to the number of passengers in each car, avoiding blind waiting and improving the carrying capacity of the train.

Description

technical field [0001] The present invention relates to the technical field of train transport capacity, in particular to a method, device and system for detecting congestion degree of carriages based on 3D radar scanning. Background technique [0002] At present, during the operation of the train, before the train arrives at the station, the passengers on the station cannot know the number of passengers in each compartment. Thereby when waiting for a train, due to the unpredictability of the crowded situation of each compartment, one can only wait blindly. Especially during peak hours, the parking time of vehicles is short, and passengers cannot predict the degree of congestion of each train compartment, which may cause some compartments to be very crowded, while some compartments are very loose, resulting in waste of space and reducing the carrying capacity of the train. When there are too many passengers, it will also cause passengers to stay in the station to a certain ...
