Embodiment Construction
[0022] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.
[0023] Such as figure 1 As shown, the embodiment of the present invention provides a road height limit early warning method based on the height limit frame. The beam of the height limit frame is provided with a laser ranging device and a camera. The method includes the following steps:
[0024] 110. Control the laser distance measuring device to emit a first laser beam, the propagation path of the first laser beam is perpendicular to the beam of the height-limiting frame, parallel to the road surface, and opposite to the driving direction of the road.
[0025] Specifically, a plurality of laser distance measuring devices are arranged on the crossbeam of the height limiter, and each laser distance measuring device co...

The invention relates to a road height limitation pre-warning method and device based on a height limitation frame and a storage medium. A laser range finder and a camera are arranged on a cross beamof the height limitation frame. The method comprises steps as follows: controlling the laser range finder to emit a first laser beam; when a second laser beam reflected by the front end of a vehicle is received by the laser range finder, determining real-time vertical distance between the front end of the vehicle and the height limitation frame according to time difference of the emitted first laser beam and the received second laser beam; when the real-time vertical distance is reduced to a preset threshold, controlling the camera to shoot thevehicle to obtain a vehicle image of the vehicle;determining a license plate number of the vehicle according to the vehicle image, displaying the license plate number on a display device, and controlling an alarm device to give an alarm. According to the technical scheme, whether an over-high vehicle exists on the road can be detected in real time, when the over-high vehicle exists, the pre-warning can be given to a driver in time, and the vehicle is prevented from impacting the height limitation frame.
Description
technical field [0001] The invention relates to the technical field of electronic equipment, in particular to a road height limit early warning method, device and storage medium based on a height limit overpass. Background technique [0002] In order to prevent super-high vehicles from colliding with tunnels in the road or overloading, etc., the height of vehicles is often limited by setting height-limiting racks. However, if the driver has a wrong memory of the height of the vehicle he is driving, the vehicle will hit the overhead limiter and cause a traffic accident, resulting in traffic paralysis. Contents of the invention [0003] In order to issue early warning to drivers in time when the vehicle is too high and avoid traffic accidents, the present invention provides a road height limit early warning method, device and storage medium based on the height limit highway. [0004] The technical scheme that the present invention solves the problems of the technologies des...
