Embodiment Construction

[0025] In order to allow those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0026] like figure 1 As shown, this embodiment provides a panoramic view system for a two-section articulated vehicle, which includes a fisheye camera, an angle sensor structure and a data acquisition processor. The video images collected by the fisheye camera with an angle of at least 180 degrees and the angle information collected by the articulated plate angle sensor device are processed by the data acquisition processor to obtain a panoramic view image of the perimeter area of ​​the articulated engineering vehicle.

[0027] Among them, the layout scheme of the fish-eye camera is as follows: for two articulated vehicles, three fish-eye cameras are respectively arranged on the front head and the rear compartment, and the fish-eye cameras of the ...

Abstract

The invention provides a panoramic around-looking system of a two-section articulated vehicle. The system comprises fisheye cameras, an angle sensor structure and a data acquisition processor, and thepanoramic around-looking system processes video images collected by three fisheye cameras which are installed on a vehicle head or a carriage respectively and have orientation field angles of at least 180 DEG and angle information collected by a hinge disc angle sensor through a data collection processor to obtain a panoramic around-looking image of a peripheral area of the hinge engineering vehicle, wherein for two articulated vehicles, the three fisheye cameras are arranged on the front vehicle head and the rear carriage. Through the design of an angle sensor mounting structure, the effectthat the angle sensor is not affected by vehicle bumping is achieved. The installation position design of the fisheye cameras and the design of a calibration method can generate a panoramic around-looking image covering the periphery 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...
