Embodiment 1

[0055] Embodiment 1: A vehicle height limit obstacle warning system based on binocular laser, see Figure 2-Figure 5 , including two laser ranging sensors 1, 2, and a control and alarm module.

[0056] The two laser ranging sensors are respectively fixedly installed on both sides of the instrument panel at the front end of the vehicle through the mounting plate 3, and the two laser ranging sensors are kept at the same height, and the optical paths emitted by the two laser ranging sensors are on a straight line. It forms an included angle of ≤5 degrees with the horizontal plane where the instrument panel at the front end of the vehicle is located; the two laser ranging sensors 1 and 2 are laser ranging sensors A and laser ranging sensors B respectively, and are set on the upper surface of the mounting plate 3 There are fixing slots, the laser ranging sensor A and the laser ranging sensor B are respectively fixed in the fixing slots on the two mounting plates 3, and the control ...

Embodiment 2

[0060] Embodiment 2: A vehicle height limit obstacle early warning method based on binocular laser, using the vehicle height limit obstacle early warning system in embodiment 1, and two laser ranging sensors are fixedly installed on both sides of the front instrument panel of the vehicle through the mounting plate respectively , the two laser ranging sensors are kept at the same height, and the angle of the laser ranging sensors is adjusted by adjusting the bolt, so that the angle between the straight line of the optical path emitted by the two laser ranging sensors and the horizontal plane of the instrument panel at the front of the vehicle is ≤5 degrees; When the vehicle is running, the laser ranging sensor measures the straight-line distance d between the front end of the vehicle and the obstacle in front at a fixed frequency 0 , C represents the height of the laser ranging sensor from the road surface, and the height V of the obstacle in front is calculated through the trig...

Abstract

The invention discloses a vehicle height-limiting barrier early-warning system and method based on binocular lasers. The system comprises two laser ranging sensors and a control and warning module. The two laser ranging sensors are fixedly installed on the two sides of a vehicle front end instrument desk through installation plates respectively. The two laser ranging sensors are kept at the same height. An included angle smaller than or equal to 5 degrees is formed between the straight line where the light emitted by the two laser ranging sensors is located and the horizontal plane where the vehicle front end instrument desk is located. The control and warning module comprises an MCU control unit, a power module, a storage module, an SRAM module and a warning module. The warning module comprises a warning lamp and a buzzer. The height-limiting barrier detection can be conducted only with the two laser ranging sensors, the system has the advantages of being low in cost and convenient toinstall and being not restrained by the low light illumination intensity at night, and the firm foundation is laid for the large-scale application and popularization of the system.

Description

technical field [0001] The invention relates to the technical field of vehicle height limit obstacle early warning, in particular to a vehicle height limit obstacle early warning system and early warning method based on binocular laser. Background technique [0002] During the driving process, the vehicle will encounter height-limited obstacles such as height-limited poles and arched bridges. Safely pass through height-limited obstacles, and can send out an alarm signal to remind the driver to slow down or stop in time to avoid accidents. [0003] When the vehicle is driving, how to accurately detect and perceive the height-limited obstacles is the key technology of the vehicle height-limited obstacle detection and early warning system. In the current research field at home and abroad, many algorithms and implementation methods have been proposed for the obstacle detection research on the vehicle driving path. For example, the computer vision method of color CCD, in additi...
