Dual view-field dynamic-trajectory reverse image system

Abstract

The invention relates to a dual view-field dynamic-trajectory reverse image system, which is characterized by comprising a wide angle reverse camera, a steering wheel turning angle sensor, a reverse image control system and a display, wherein the reverse image control system is used for acquiring vehicle gears, the steering wheel turning angle and driver reverse image view-field selection information; the reverse image control system is used for controlling the wide angle camera to acquire vehicle rear images and to respectively send the images to a reverse trajectory projection unit and a reverse image overlook conversion unit; a reverse trajectory calculation unit is used for acquiring the steel wheel turning angle, calculating a reverse trajectory and a distance mark line, and sending them to the reverse trajectory projection unit; the reverse trajectory projection unit is used for projecting the reverse trajectory line and the distance mark line to the images, and sending the images overlapped with the reverse trajectory line and the distance mark line to the display; and the reverse image overlook conversion unit is used for converting the vehicle rear images into overlook images, projecting the reverse trajectory and the distance mark line to the overlook images, and sending to the display. The dual view-field dynamic-trajectory reverse image system provided by the invention can be widely applied to providing more accurate reference information for drivers in the vehicle reverse process.

Description

technical field [0001] The invention relates to a reversing assistance system, in particular to a dual-view dynamic trajectory reversing image system for providing reversing reference information to drivers. Background technique [0002] With the rapid increase of car ownership in China, parking places such as roads and parking lots are becoming more and more crowded, and the available parking spaces are becoming less and less. At the same time, the number of unskilled novices in the fast-growing driver population is also increasing year by year. Due to the influence of the structure of the car and the limited vision of the driver, reversing has become one of the main difficulties in car driving. The research of the University of Michigan in the United States shows that the accidents caused by parking account for 44% of all kinds of accidents, and about 50% of the parking accidents are caused by reversing. It can be seen that reversing is an important cause of vehicle accid...

Problems solved by technology

[0004] However, the existing reversing imaging system uses a wide-angle camera to capture images that are very distorted, and it is difficult for the driver to judge the distance from the vehicle to the rear obstacles from the images, especially obstacles with a certain height from the ground. The reason is that the driver feels the distance through the image is farther than the actual distance, and if the reverse operation is performed according to the image display, a collision may occur
