Laser type vehicle detecting method and device thereof

Abstract

An embodiment of the invention discloses a laser type vehicle detecting method and a device thereof. The method comprises the steps of detecting vehicle data of the scanning area of a to-be-arrived laser scanning unit on a road, and performing processing for obtaining a processing result; and if no vehicle exists, stopping rotation of a motor or reducing rotating speed of the motor, and making a laser emitting tube stop laser emitting; and if the vehicle exists, increasing or reducing the rotation speed of the motor according to the detected vehicle speed, making the laser emitting tube emit laser; obtaining the vehicle information through identification according to vehicle contour information, and performing statistics for obtaining a vehicle information statistics result. According to the laser type vehicle detecting method and the device thereof, through stopping rotation of the motor or reducing the rotation speed of the motor and making the laser emitting tube do not emit laser when no vehicle is determined, and increasing or reducing the rotation speed of the motor and making the laser emitting tube emit laser when existence of the vehicle is determined, the working state ofthe motor and the laser emitting tube can be reasonably controlled according to the actual condition of the road, thereby prolonging service life of the motor and the laser emitting tube, and reducing maintenance cost and equipment purchasing cost.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of intelligent transportation, and in particular to a laser vehicle detection method and device.

The scanning laser ranging sensor is a high-precision, high-tech precision product. Its application environment in the field of traffic situation investigation is relatively complicated. In most of the time, there are no vehicles passing through the detection area on the road, but the scanning laser ranging sensor The motor and laser light-emitting tube in the sensor are always in working condition. Long-term continuous work will inevitably reduce the service life of the motor and laser light-emitting tube, reduce the normal use time of the equipment, increase the cost of maintenance and procurement of equipment, and affect the investigation of traffic conditions.

[0003] In the process of realizing the embodiment of the present invention, the inventor found that the motor and the laser light-emitting tube in the existing method scanning laser distance sensor are always in the working state, which reduces the service life of the motor and the laser light-emitting tube, and increases the cost of maintenance and purchasing equipment. cost
