Vehicle door scratch pre-warning method

Abstract

The invention provides a vehicle door scratch pre-warning method and relates to the technical field of vehicle safety. The vehicle door scratch pre-warning method comprises the following steps of additionally mounting binocular cameras on two sides of a vehicle; when a user pulls a vehicle door handle from the interior of the vehicle to open a door, starting the binocular cameras and identifying an object near the vehicle door by using an image identification technology; judging whether a vehicle door scratch problem is probably caused by the object or not (for example, shrubs and so on may not cause vehicle door scratch, but buildings or vehicles may cause vehicle door scratches); and then calculating the distance from the object near the vehicle door to the vehicle door according to a binocular camera distance measuring principle; when the object is closer to the vehicle door so that the door opening space is not enough, reminding the user of insufficient door opening space through speech; and then enabling the user to control the vehicle door opening or adjust the parking space so as to avoid the vehicle door scratch problem.

Description

technical field [0001] The invention relates to the technical field of vehicle safety, in particular to a method for early warning of car door scratching. Background technique [0002] With the development of society, the number of vehicles is increasing. According to statistics, the number of cars in the world has exceeded 1 billion. With the continuous increase of vehicles, the parking space in cities is getting smaller and smaller. It is due to the lack of parking space, and it is impossible for the owner to ensure that the doors on both sides have enough space to open every time the parking position is reached. Or other vehicles collide, causing the scraping of the car door, making the car owner suffer economic losses. [0003] The existing common vehicle ranging camera for obstacle avoidance draws a distance scale line on the image collected by the camera, and then displays it on the car display screen. The driver judges the approximate distance between the obstacle an...

Problems solved by technology

There are some defects in radar ranging, such as insensitivity to some small objects. For example, the measurement parameters of a certain product show that the effective detection distance of a 75mm tube is only 100cm, which is smaller than the door size of many models.

However, there is almost no response to small things such as barbed wire; in addition, the current reversing radar basically adopts the ultrasonic scheme, which generally requires the radar to be about 50 cm away from the ground, and there are few installation positions on the side of the car.
