Embodiment 1
[0053] Such as figure 1 As shown, a passenger counting system includes a passenger video acquisition module, a video data processing module, a video data analysis module, a passenger counting module, and a boarding and disembarking direction recognition module connected in sequence;
[0054] The passenger video acquisition module includes a laser transmitter, a video acquisition card, and a camera for collecting video images of passengers getting on and off the bus; the video acquisition system uses a laser transmitter with a wavelength above 800nm. The camera is a CCD camera with a visible light cut-off filter, which can transmit light waves above 800nm, and a filter with a visible light cut-off of 400-750nm is used to receive reflected laser beams and filter visible light at the same time to exclude light below 800nm. The impact of visible light waves on video capture. The laser emitter is in a line or star shape, and is used to project the laser beam in a line or star shap...
Embodiment 2
[0068] Such as figure 2 Shown, a kind of passenger counting method comprises the following steps:
[0069] 1) Environmental deployment: place the laser emitter and camera at a predetermined location, and connect the camera to the video capture card; the wavelength of the laser emitted by the laser emitter is above 800nm, the effective angle is above 120°, and the camera has a visible light cut-off filter The light sheet, so that the camera only receives the reflection of the laser light. The angle of the laser generator and the camera is determined according to the size of the boarding and disembarking area of the coach.
[0070] 2) Passenger video collection: through the deployed camera, collect the video of passengers getting on and off the car including the laser line; when the passenger passes the laser beam, the camera with the band-pass filter only receives the reflection of the laser, and the height of the laser reflection beam will change. and collected by the cam...
