Problems solved by technology

[0002] With the rapid development of the automobile industry, the number of automobiles in our country continues to increase. A large number of automobiles have entered the family and become a very important means of transportation in human life and production. However, it has also brought many traffic accidents and brought a lot of inconvenience to our travel.
Especially when a car stopped on the side of the road suddenly opens the door, the passing non-motor vehicles and motor vehicles have no time to avoid, thus causing traffic accidents and causing unnecessary losses
In the prior art, although there is a control method for the safe opening of the car door, this method has great limitations.
It is currently proposed to use radar transmitters to detect rear vehicles, but this method has great limitations. It cannot accurately judge the vehicles that exist at a relatively long distance behind, and the calculation error is large, and it cannot accurately determine the distance and speed of pedestrians and vehicles. And the acceleration is identified and calculated, so as to accurately control the safe opening of the door, and the cost of radar is relatively high, which is not conducive to popularization in automobiles

Embodiment

[0077] see Figure 4 , after a car is designed, the distance between the rearview mirror and the bumper is determined, that is, the longitudinal distance d between the camera A at the rearview mirror and the camera B at the bumper is a known fixed value.

[0078] The distance between the target object and the camera located at the rearview mirror is expressed by L 2 Indicates that the distance between the target object and the camera at the bumper is expressed by L 1 means, then:

[0079] L 2 =d+L 1 .

[0080] The size of the target object is a, and the size of the entire image captured by the camera A located at the rearview mirror is b 2 , the camera B located at the bumper collects the entire picture containing the target object with a size of b 1 , then the pixel ratio of the target object in the picture captured by the camera A located at the rearview mirror is:

[0081]

[0082] The pixel ratio of the target object in the picture captured by the camera B locate...

Abstract

The invention discloses a processing method and system for safely opening an automobile door. When a driver pulls over an automobile and the driver and passengers in the automobile want to open the automobile door to get on or get off the automobile, a central processing unit in the automobile detects whether pedestrians, non-motorized vehicles and motor vehicles are behind the automobile or not according to four cameras on rearview mirrors and a back bumper and judges whether the automobile door can be opened or not according to distances of the pedestrians, the non-motorized vehicles and the motor vehicles; the central processing unit judges according to acquired information, and the automobile door can be opened if no pedestrians, non-motorized vehicles and motor vehicles are behind the automobile or the pedestrians, the non-motorized vehicles and the motor vehicles are far away from the automobile; if the pedestrians, the non-motorized vehicles and the motor vehicles are behind the automobile in short distances, the automobile door cannot be opened, and the central processing unit sends alarms to the passengers in the automobile. Therefore, collision of open automobile door with the pedestrians, the non-motorized vehicles and the motor vehicles approaching to the rear of the automobile can be avoided, safety is improved, and user experience is improved as well.

Description

technical field [0001] The invention belongs to the field of automobile intelligent control, and in particular relates to a processing method and system for opening a safety door. Background technique [0002] With the rapid development of the automobile industry, the number of automobiles in our country continues to increase. A large number of automobiles have entered the family and become a very important means of transportation in human life and production. However, it has also brought many traffic accidents and brought a lot of inconvenience to our travel. . Especially when the automobile that stops on the roadside opens the car door suddenly, the non-motor vehicle and motor vehicle of passing have no time to dodge, thereby traffic accident takes place, causes unnecessary loss. And in the prior art, although there is a control method proposed for safe opening of the car door, there are great limitations in this method. It is currently proposed to use radar transmitters...
