Embodiment 1

[0020] see figure 1 , the present invention provides a collision avoidance method for when a vehicle door is opened, which is applied to a vehicle including a panoramic parking assistance system. Wherein, the panoramic parking assistance system is to install camera devices at the front, rear, left, and right sides of the vehicle, and the four camera devices provide the people in the car with panoramic images around the vehicle to help the people in the car park their cars. Observe the surrounding road conditions. The anti-collision method mainly utilizes the image frames provided by at least one of the left, right and rear camera devices of the vehicle to determine the actual movement data of the target object relative to the vehicle for early warning. Wherein, the target objects include but are not limited to: motor vehicles, non-motor vehicles, pedestrians and the like. The collision avoidance method is mainly performed by a collision avoidance system. Wherein, the collis...

Embodiment 2

[0049] In order to avoid unnecessary early warning prompts by the collision avoidance system, the collision avoidance method further includes: determining by monitoring the current driving speed of the vehicle, or based on the setting operation of the human-machine interface by the personnel in the vehicle Whether to provide an early warning report to the personnel in the vehicle and / or control the steps of locking each vehicle door. (not shown)

[0050] Specifically, the collision avoidance system obtains the current driving speed of the vehicle through an interface with the vehicle driving system, and when the driving speed exceeds a preset driving speed threshold, the execution of step S1 or step S3.

[0051] Alternatively, the anti-collision system provides an interactive interface to the occupants of the vehicle, and when the occupants press the start button through the interactive interface, the anti-collision system is based on the occupant's The operation instruction...

Embodiment 3

[0053] see figure 2 , the present invention also provides an anti-collision system for when a vehicle door is opened, which is applied to a vehicle including a panoramic parking assistance system. Wherein, the panoramic parking assistance system is to install camera devices at the front, rear, left, and right sides of the vehicle, and the four camera devices provide the people in the car with panoramic images around the vehicle to help the people in the car park their cars. Observe the surrounding road conditions. The collision avoidance method mainly utilizes the image frames provided by at least one of the left, right and rear camera devices 2 of the vehicle to determine the actual movement data of the target object relative to the vehicle for early warning. Wherein, the target objects include but are not limited to: motor vehicles, non-motor vehicles, pedestrians and the like.

[0054] The anti-collision system 1 includes: an image preprocessing unit 11 , an actual movem...

Abstract

The present invention provides an anti-collision method and system for when a car door is opened, which is applied to a vehicle including a panoramic parking assistance system. The captured image frames, and extract the relevant information of the target object from each of the image frames; based on the correspondence between the coordinate system of each of the image frames and the actual road coordinate system, determine the corresponding information of each of the relevant information in the actual road. The actual movement data of the target object relative to the vehicle; when the actual movement data of the target object is within the preset early warning range, an early warning report is made to the personnel in the vehicle, and / or the control on each door of the vehicle The lock, wherein the warning range includes: a first warning interval formed based on the length of the side of the vehicle and the opening width of the vehicle door. The application can avoid the danger of traffic accidents caused by blind spots when people in the car open the door.

Description

technical field [0001] The invention relates to the field of computers, in particular to an anti-collision method and system for opening a car door. Background technique [0002] For ordinary vehicles, due to the limitation of the vehicle structure, there are many visual blind spots when the occupants observe the situation outside the vehicle; This makes the occupant in the car unable to be sure that the vehicle is in absolute safety when opening the door. This may cause the occupant in the car to collide with the pedestrians and cyclists outside when opening the door and cause a car accident. [0003] In response to the above problems, the current common method is to use active sensors such as radar, which can provide depth information of obstacles such as vehicles and pedestrians around the vehicle, which has unique advantages in harsh environmental conditions, but due to high cost constraints, currently only It is commercialized on some high-end cars. In recent years, ...
