Embodiment 1

[0018] A bus passenger flow statistics method based on a binocular camera, comprising: collecting passenger flow image information at the entrance of a bus based on the binocular camera; Passenger traffic data of vehicles.

[0019] Based on the binocular camera, the image information of the passenger flow at the bus entrance is collected, specifically: when the bus entrance door is opened, a door opening signal is sent to the binocular camera; the binocular camera is activated after receiving the door opening signal, and the passenger flow image at the bus entrance is collected. information. Input the collected passenger flow image information into the trained bus passenger flow statistical model to obtain the passenger flow data entering the bus, specifically: correcting and projecting the passenger flow image information at the bus entrance collected by the binocular camera to obtain the corrected picture ; Calculate the disparity map on the corrected picture to obtain the ...

Embodiment 2

[0032] Based on the binocular camera-based bus passenger flow statistics method described in Embodiment 1, this embodiment provides a bus passenger flow statistics system based on binocular cameras, such as figure 1 As shown in the figure, it includes: the image acquisition module includes a binocular camera 1 electrically connected to the passenger flow statistics host 2, which is used to collect the passenger flow image information at the bus entrance based on the binocular camera; the passenger flow statistics module is built in the passenger flow statistics host 2 Internally, it is used to input the collected passenger flow image information into the trained bus passenger flow statistical model to obtain the passenger flow data entering the bus; the GPS module 3 is electrically connected to the passenger flow statistics host 2 to obtain the current bus position , to judge whether the bus has entered the bus station, and start the counting system; 4G module 4 is electrically...

Abstract

The invention discloses a bus passenger flow volume statistical method and system based on a binocular camera in the technical field of image recognition, and the method comprises the steps: collecting passenger flow image information at a bus entrance based on the binocular camera; and inputting the acquired passenger flow image information into the trained bus passenger flow statistical model to obtain the passenger flow data of the entering bus. The method and system has the advantages of being high in passenger flow volume statistical accuracy, higher in applicability to various types of binding and complex backgrounds and the like.

Description

technical field [0001] The invention belongs to the technical field of image recognition, and in particular relates to a method and system for bus passenger flow statistics based on binocular cameras. Background technique [0002] At present, common people flow counting techniques include manual counting methods, IC card-based methods and traditional machine learning-based passenger flow counting methods; manual counting mainly records the number of people entering and leaving through the staff, and manually summarizes statistics at the terminal station. The advantage of this method is that the accuracy rate is high, but the workload of personnel is relatively large and it is impossible to network online statistics in real time. Based on the IC card method, the IC card stores a large amount of personal information. This method records the ID of each card-swiping person for passenger flow statistics. The advantage is that there is no need to arrange additional staff to count ...
