Profile size is a dynamic measurement system for test vehicles based on laser high-speed dynamic scanning. It mainly includes measurement, including system calibration, data preprocessing, edge point positioning and vehicle profile size data calculation. The system is a fully automatic, non-contact measurement system, which can calculate the length, width and height of the vehicle in an instant.

The laser scanning relative image has unique application advantages and data characteristics in the measurement of vehicle profile size, including:

The laser pulse emission has strong directionality, which is good for algorithm processing.

The model must be selected with a stronger environment, adaptability is not sensitive to changes in light, adapt to night and outdoor working environment, especially can be used at -30° temperature.

The vehicle enters the range finder from the end where the first laser scanning unit (1) and the second laser scanning unit (2) are installed and the laser scanner group is always switched on to obtain data.

The height of the body from the ground and the coordinates of the left and right edges are obtained by scanning the body. The length measuring laser scanning unit (3) obtains the horizontal distance to the front of the car, and the system will record the length measuring laser scanner at this moment. The horizontal distance to the front of the vehicle and quickly calculate the length, width, and height of the vehicle.
