Embodiment 1

[0062] see figure 2 , figure 2 It is a schematic flowchart of a vehicle collision early warning method disclosed in an embodiment of the present invention. Such as figure 2 As shown, the vehicle collision warning method may include the following steps:

[0063] 101. The early warning system uses radar sensors and cameras to detect obstacles.

[0064] In this embodiment of the present invention, the radar sensor may be an ultrasonic radar sensor, a millimeter wave radar sensor, or a laser radar sensor, etc., which are not limited in this embodiment of the present invention. The radar sensor can be installed at the front of the vehicle, the rear of the vehicle and / or the doors on both sides of the vehicle, and the number of the radar sensor can be one or more. The camera may be an ordinary optical camera or a 360° panoramic camera, which is not limited in this embodiment of the present invention. Further, the viewing range of the camera may partially or completely overla...

Embodiment 2

[0083] see image 3 , image 3 It is a schematic flowchart of another vehicle collision early warning method disclosed in the embodiment of the present invention. Such as image 3 As shown, the vehicle collision warning method may include the following steps:

[0084] 301. The early warning system detects whether the vehicle is in reverse gear; if yes, execute step 302; if no, end this process.

[0085] Since the driver has many visual blind spots when reversing, the embodiment of the present invention executes the following steps 302 to 307 when it is detected that the vehicle needs to perform a reversing operation, so as to improve the accuracy of obstacle detection when reversing and improve the safety of reversing. Driving safety.

[0086] 302. The early warning system uses radar sensors to detect several pre-divided early warning planning areas around the vehicle.

[0087] In the embodiment of the present invention, please refer to Figure 4 , Figure 4 It is an ex...

Embodiment 4

[0109] see Figure 5 , Figure 5 It is a structural schematic diagram of a vehicle collision warning system disclosed in an embodiment of the present invention. Such as Figure 5 As shown, the vehicle collision warning system may include:

[0110] The first detection unit 501 is configured to detect obstacles by using a radar sensor and a camera; the camera may be a 360° panoramic camera, which is not limited in this embodiment of the present invention. Specifically, image recognition algorithms such as deep learning can be used to extract obstacles from images captured by the camera.

[0111] The first determination unit 502 is configured to determine the warning level according to the detection result of the radar sensor and the detection result of the camera;

[0112] Among them, if the detection result of the radar sensor indicates that there is an obstacle, and the detection result of the camera also indicates that there is an obstacle, the early warning level is dete...

Abstract

The invention discloses a vehicle collision early-warning method and system, a vehicle and a storage medium. The method comprises the following steps: carrying out obstacle detection by virtue of a radar sensor and a camera; determining an early-warning level according to a detection result of the radar sensor and a detection result of the camera; determining the virtual images of an obstacle corresponding to the early-warning level; and outputting and displaying the real environment images shot by the camera, and superposing and displaying the virtual images on the real environment images, wherein the virtual images of the obstacles corresponding to different early-warning levels are different. By implementing the embodiment of the invention, detection dead zones for the obstacle can be reduced, so that the collision risk of the vehicle is lowered.

Description

technical field [0001] The present invention relates to the technical field of driving assistance, in particular to a vehicle collision warning method, system, vehicle and storage medium. Background technique [0002] At present, most vehicles are equipped with collision warning systems (such as reversing radar), which can detect obstacles in low-speed reversing scenes, and give prompts and warnings through sound or reversing images when obstacles are detected. [0003] It has been found in practice that when designing a collision warning system, the number of radars that need to be used is generally reduced as much as possible from the perspective of cost and aesthetic appearance. In addition, the radar will be installed in a more beautiful position as much as possible, but this installation position may sacrifice part of the radar performance. In addition, the radar sensor itself has certain limitations. Taking ultrasonic radar as an example, the coverage of the sound wa...
