Abstract

The invention relates to the field of intelligent transportation, in particular to a camera triggering method based on a laser radar. The camera triggering method comprises the steps of: acquiring aninitial road surface parameter through using a laser radar module, and setting a road surface change threshold value, wherein the initial road surface parameter is a laser radar module measurement distance or a laser radar module vertical road surface distance under a vehicle-free condition, and the road surface change threshold value is a change threshold value of an initial road surface parameter; measuring the distance to the road surface by means of the laser radar module, comparing an actual road surface parameter with the initial road surface parameter, and triggering a camera to photograph by the laser radar module when a difference value between the actual measurement distance or the vertical road surface distance of the laser radar module and the initial road surface parameter exceeds a set road surface change threshold value. According to the camera triggering mode, triggering can be started after parameters are set, manual adjustment is not needed, operation is easy, the whole triggering process is conducted through the laser radar module, the triggering accuracy rate depends on the ranging precision of the laser radar module, and therefore the triggering accuracy rate is high.

Description

technical field [0001] The present disclosure relates to the technical field of intelligent transportation, and in particular to a lidar-based camera triggering device and method. Background technique [0002] With the rapid increase of the number of vehicles per capita, the increase of vehicles not only brings convenience to people's transportation, but also brings enormous pressure to the management of the transportation system. In order to solve various traffic problems caused by the rapid development of ground traffic, traffic cameras are widely used in the field of traffic management. In the practical application of traffic cameras, triggering their work is a key point. The existing triggering technologies for traffic cameras include: geomagnetic coil triggering and camera motion detection algorithms. Among them, the construction of the installation of the geomagnetic coil is complicated, and if the outgoing line fails, the maintenance will be cumbersome, and it will h...
