Embodiment 1

[0022] see figure 1 , The present invention provides a vehicle early warning method, which is applied to a vehicle including a panoramic parking assistance system. Wherein, in the panoramic parking assist system, camera devices are installed at the front, rear, left, and right sides of the vehicle, and the four camera devices provide the driver with panoramic images around the vehicle to help the driver observe when parking. surrounding traffic. The vehicle early warning method mainly utilizes image frames provided by at least one of the left, right and rear camera devices of the vehicle to determine the actual driving data of the target vehicle relative to the vehicle for early warning. The vehicle early warning method is mainly executed by a vehicle early warning system.

[0023] In step S1, the vehicle early warning system respectively acquires image frames captured by at least one camera device located in the panoramic parking assist system of the vehicle, and extracts r...

Embodiment 2

[0052] In order to avoid unnecessary early warning prompts by the vehicle early warning system, the vehicle early warning method further includes: monitoring the current driving speed of the vehicle, or determining whether to The step of the driver raising an early warning report. (not shown)

[0053] Specifically, the vehicle early warning 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, it starts to execute step S1 or step S1 in Embodiment 1. S3.

[0054] Alternatively, the vehicle early warning system provides an interactive interface to the driver of the vehicle, and when the driver presses the start button through the interactive interface, the vehicle early warning system executes based on the driver's operation instruction Step S1 or S3 in Embodiment 1.

Embodiment 3

[0056] see figure 2 , The present invention provides a vehicle early warning system, which is applied to a vehicle including a panoramic parking assistance system. Wherein, in the panoramic parking assist system, camera devices 2 are respectively arranged at the front, rear, left, and right sides of the vehicle, and the four camera devices 2 provide the driver with panoramic images around the vehicle to help the driver in parking. Observe the surrounding road conditions. The vehicle warning system 1 mainly uses the image frames provided by at least one of the left, right and rear camera devices 2 of the vehicle to determine the actual driving data of the target vehicle relative to the vehicle for early warning. The vehicle early warning system 1 includes: an image preprocessing unit 11 , an actual driving information acquisition unit 12 , and an early warning unit 13 .

[0057] The image pre-processing unit 11 is used to respectively obtain image frames captured by at least...

Abstract

The present invention provides a vehicle early-warning method and system applied to vehicles including panorama-based parking auxiliary systems. The early-warning method comprises the steps of obtaining picture frames captured by at least one path of camera device of the panorama parking auxiliary system by the early-warning system, and extracting related information of target vehicles from the picture frames; determining actual driving data of the target vehicles corresponding to the related information relative to the vehicle in an actual road based on the relationship between the coordinate systems of the picture frames and coordinate systems of the actual road; and presenting an early-warning report to a driver of the vehicle when the actual driving data of the target vehicles are in a preset early-warning range. Danger of traffic accidents caused by dead zones when the driver is turning, overtaking and normally driving can be prevented.

Description

technical field [0001] The invention relates to the field of computers, in particular to a vehicle early warning method and system. Background technique [0002] For general vehicles, because there are many visual blind spots outside the visual range of the vehicle side rearview mirror, and when the driver concentrates on driving the vehicle, the driver's field of vision will also be reduced, which makes driving The driver cannot be sure that the vehicle is absolutely safe when performing lane changing operations. Therefore, the driver will briefly shift his attention to the blind spot area on the side of the vehicle for observation, which will cause the driver to be unable to concentrate on the situation ahead of the vehicle and cause a car accident. Or, when the driver is fatigued after driving for a long time, it is easy to cause the driver's psychological burden on driving safety. [0003] In view of the above problems, the current common method is to use active sensor...
