A realization method for variable-angle panoramic view system for articulated engineering vehicles

Abstract

The invention provides a panoramic view system for two articulated vehicles, which includes a fisheye camera, an angle sensor structure and a data acquisition processor. The video images collected by three 180-degree fisheye cameras and the angle information collected by the articulated disc angle sensor are processed by the data acquisition processor to obtain a panoramic view image of the perimeter area of ​​the articulated engineering vehicle; wherein: for two articulated vehicles, the Fisheye cameras are arranged on the front and rear compartments, and three fisheye cameras are arranged on each. The invention achieves the effect that the angle sensor is not affected by vehicle bumps through the design of the angle sensor installation structure. The installation position design and calibration method design of the fisheye camera can generate panoramic surround-view images covering the surroundings of the articulated engineering vehicle.

Description

technical field [0001] The invention belongs to the field of vehicle safety assistance and automotive electronics, and in particular relates to a method for realizing a variable-angle panoramic view system for an articulated engineering vehicle. Background technique [0002] In the past few decades, with the continuous development of the transportation industry and the rapid growth of car ownership, road safety accidents have continued to increase. Drivers judge 80% of external traffic information from vision, and visual blind spots are often an important cause of traffic accidents. Since the panoramic surround view system has the advantages of reducing the driver's visual blind spot and helping the driver better judge traffic conditions, it has been widely developed and applied in passenger cars. Articulated construction vehicles have long bodies and angle the nose and body when cornering, creating a larger blind spot. Conventional panoramic surround view systems cannot s...

AI Technical Summary

Problems solved by technology

Conventional panoramic surround view systems cannot solve the problem of increased blind spots in the hinge area caused by vehicle steering

In addition, articulated engineering vehicles have large blind spots when driving, and traffic accidents are more likely to occur. Therefore, the variable-angle panoramic view system for articulated engineering vehicles is of great significance for improving vehicle safety.
