Embodiment 1
[0062] Such as figure 1 with figure 2 As shown, this embodiment provides a multi-camera complex scene adaptive vehicle collision warning device, including a multi-camera perception module, a data processing and calculation module, and a collision alarm module. The multi-camera perception module is connected to the data processing and calculation module to detect The image information of the road ahead and obstacles received is transmitted to the data processing and computing module; the multi-camera perception module includes the first camera, the second camera and the third camera whose focal lengths are successively reduced, and the first camera, the second camera and the third camera Both are fixed-focus cameras; the data processing and calculation module is used to perform vehicle detection, tracking, and front-to-back distance calculation on the image information according to the set built-in collision warning method. The collision warning information is generated and s...
Embodiment 2
[0068] Such as figure 1 with figure 2 As shown, the present embodiment provides an early warning method for the multi-camera complex scene adaptive vehicle collision early warning device, including the following steps:
[0069] (1) The multi-camera perception module transmits the detected image information of the road ahead and obstacles to the encoding module;
[0070] (2) The encoding module encodes the image information sent by the multi-camera perception module, converts it into a unified data format, and sends it to the camera image acquisition module in the processing module;
[0071] (3) The camera image acquisition module collects the multi-camera image information sent by the encoding module, performs image preprocessing, including filtering, noise reduction and image format conversion, and converts the original RGB format image sent by the multi-camera perception module into a grayscale format.
[0072] (4) The driving scene perception module receives the current ...
