Embodiment Construction

[0049]It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0050] refer to figure 1 , figure 1 It is a schematic flowchart of an embodiment of the vehicle anti-collision early warning method of the present invention. In this embodiment, the vehicle anti-collision early warning method includes:

[0051] Step S10, collecting the image frame of the video image in front of the vehicle road;

[0052] In this embodiment, a camera device (such as a camera) is used to capture the environment in front of the road of the own vehicle and generate a corresponding video image, and the video image is specifically an RGB color image. It should be noted that the photographing by the camera equipment can be taken while the vehicle is driving, or can be taken when the vehicle is stopped (in a parking state). The range of the angle is not limited, and may specifically be for the driving lane...

Abstract

The invention discloses a vehicle anti-collision early warning method, comprising: collecting an image frame of a video image in front of the road of the own vehicle; determining whether there is a short-distance preceding vehicle in front of the road of the own vehicle through the image frame; When it is determined that there is a short-distance vehicle in front, determine the prominent region of the rear feature of the preceding vehicle from the image frame; track the prominent region, and record the position and / or of the prominent region in the image frame of the video image Size: judging the vehicle distance state corresponding to the recorded position and / or size change of the prominent area in the image frame of the video image, and issuing a vehicle anti-collision warning according to the corresponding vehicle distance state. The invention also discloses a vehicle anti-collision warning device. The invention can reduce the hardware cost and improve the application range and accuracy of the vehicle anti-collision warning at the same time.

Description

technical field [0001] The invention relates to the technical field of target recognition, in particular to a vehicle anti-collision early warning method and device. Background technique [0002] At present, in the prior art, radar equipment is usually used to detect the vehicle in front, and the depth information of the environment in front of the vehicle is obtained to judge the potential trend of collision between the vehicle and the vehicle in front. The angle is small, so there will be a problem of detection dead angle, which will lead to unsatisfactory detection effect and high cost of radar equipment at the same time. Contents of the invention [0003] The main purpose of the present invention is to provide a vehicle anti-collision early warning method and device, aiming to solve the technical problems of high hardware cost and unsatisfactory detection effect in the existing vehicle anti-collision technology. [0004] In order to achieve the above object, the prese...
