Abstract

The invention discloses a height measurement method and device of a highway height permitted frame for a vehicle based on binocular vision. Two wide-angle cameras and a binocular vision system are used for shooting, tracking and locating a height permitted beam target in real time, the binocular vision system is used for measuring the distance from the vehicle to the height permitted frame and therelative height of a vehicle roof in real time, early warning information is provided for drivers, driving and road traffic safety are ensured, a space geometry relation is used for calculating the height of a road frame and the distance between the vehicle and the road frame, the height measurement method and device have the advantages of being high in computing speed and less in calculation resource consumption, the real-time requirements of vehicle safety early warning are effectively met, a limit constraint binocular correction method is adopted to reduce the matching search space, two-dimensional search is reduced to one-dimensional search, the advantage of high matching speed is realized, a checkerboard calibration method is adopted, the internal parameters of the camera can be obtained effectively, and the accuracy of image depth data calculation can be ensured.

Description

technical field

[0001] The invention belongs to the technical field of driving assistance devices, and uses an image measurement method to realize real-time automatic measurement of the height of a highway overpass, specifically a method for measuring the height of a highway overpass for vehicles based on binocular vision. Background technique

[0002] The height limiter is a device that can limit the height of vehicles on the road. For the upper and lower ramps of some viaducts and some roads that do not allow heavy vehicles to pass, the protection of the roads is realized by setting the height limit to limit the passage of super-high vehicles.

[0003] The common height-limiting frame generally adopts a door-shaped structure, which is composed of two columns on both sides and a height-limiting beam on the top. The height-limiting beam is used to limit the passage of super-high vehicles. However, it is often difficult for some drivers to accurately judge whether the height...
