Angle information-based visible vehicle-backing track line forming system and method

Abstract

The invention relates to an angle information-based visible vehicle-backing track line forming system and an angle information-based visible vehicle-backing track line forming method. The angle information-based visible vehicle-backing track line forming system comprises a vehicle-backing camera, a display screen, a steering wheel corner measuring device, a vehicle-backing track calculation module and a vehicle-backing track projection module, wherein the vehicle-backing camera is arranged on the tail part of a vehicle and is used for acquiring images behind the vehicle; and the display screen, the steering wheel corner measuring device, the vehicle-backing track calculation module and the vehicle-backing track projection module are arranged in a cab. The angle information-based visible vehicle-backing track line forming method comprises the following steps of: calculating a vehicle-backing track according to a steering wheel corner; projecting the vehicle-backing track into an imaging screen coordinate system of the vehicle-backing camera; and overlapping the projected vehicle-backing track with the images behind the vehicle which are acquired by the vehicle-backing camera to display on the display screen in the cab so as to provide a vehicle-backing indication line and images around the vehicle-backing track for a driver and guide the driver to back the vehicle. At the same time, distance marking lines for showing the distance away from the tail part of the vehicle are arranged on the vehicle-backing track, so that the driver can judge the distance between obstacles behind the vehicle and the tail part of the vehicle accurately according to the distance marking lines and can be guided to back the vehicle safely.

Description

technical field [0001] The invention relates to the field of automotive electronics, in particular to a visualized intelligent reversing assistance system and method. Background technique [0002] The potential danger in the blind spot at the rear of the car often brings great loss of life and property and serious mental injury to people. According to statistics, traffic accidents caused by blind spots behind cars account for about 30% in China and 20% in the United States. In addition, with the rapid increase in the number of cars, while cars have entered thousands of households, the parking spaces in major cities have become narrower and narrower, and the requirements for drivers' reversing skills are getting higher and higher. Especially for many novice drivers or ladies, every time they reverse the car, they can be described as looking forward and backward, trembling, and if they are not careful, they will scratch or collide with adjacent vehicles. Therefore, the issue...

However, these two systems only stay at the level of "alarm" and "visual", and can only remind the driver whether there is an obstacle behind, but cannot prompt how to reverse the car to enter a specific position, so they cannot provide intelligent guidance for the reversing process.
