Problems solved by technology
At present, the vehicle can be measured to obtain parameters such as the height and focal length information of the camera or camera. However, in most cases, there is no opportunity to measure the vehicle, and parameters such as the height and focal length information of the camera or camera cannot be obtained. The captured images It will be impossible to analyze the image and perform perspective relationship conversion, resulting in a waste of resources

The embodiment of the present invention discloses a top-view image transformation method, device, and car, wherein the method includes: intercepting transformation reference lines that are parallel to each other in the actual environment from the original image captured by the vehicle-mounted equipment, and performing the transformation based on the image transformation rule. Transforming an image to generate a top view image corresponding to the first image, and making two or more conversion reference lines parallel to each other in the top view image. The bird's-eye view image transformation method, device, and automobile of the present invention, for the original image taken by the vehicle-mounted equipment, do not need to measure the parameters such as the height and focal length of the camera or the camera, and perform image processing according to the parallel relationship existing in the transformation reference line in reality. Stretch, rotate and other transformations to generate top-view images. The transformation processing is simple and easy, and it is possible to perform top-view image transformations on images from different sources.
Description
technical field [0001] The present invention relates to the technical field of image processing, in particular to a top view image transformation method, device and automobile. Background technique [0002] The images captured by the camera of the driving recorder or other vehicle-mounted equipment and the camera belong to the perspective transformation image. Due to the existence of the perspective relationship, the objects on the ground show the characteristics of being far and near small. In some cases, the image analysis of the captured image needs to convert the perspective relationship of the image into a top view, such as the detection and tracking of lane lines. Usually, the transformation of perspective relationship usually needs to obtain the height and focal length information of the camera or camera, establish the inverse transformation matrix, and then perform transformation point by point to obtain the transformed top view. At present, the vehicle can be measu...
