[0003] However, in the current vehicle detection technology, it is not very suitable to identify the location of the vehicle in the image in the form of a detection frame, for example, in the vehicle detection scene of the fisheye image, the position of the vehicle in the fisheye image The distortion is large. If the position of the vehicle in the image is marked in the form of a detection frame, on the one hand, the detection effect is not good enough, that is, the position of the marked vehicle is not accurate enough; on the other hand, the detection frame on the fisheye image has been de-distorted and after projective transformation, no longer has the correct physical meaning

The embodiment of the invention discloses a vehicle detection method and device. The method comprises the steps of obtaining a to-be-detected image; detecting the to-be-detected image by using a pre-trained vehicle detection model, and determining the detection information of a wheel grounding point of each vehicle in the to-be-detected image; and associating the detection information of the wheel grounding point corresponding to each vehicle, and outputting the detection information of a wheel grounding point set of the vehicle for each vehicle, wherein the pre-trained vehicle detection model is a model obtained by training on the basis of the sample images marked with the marked wheel grounding point sets of the sample vehicles. The detection information comprises the position information of the wheel grounding point, or comprises the position information and the orientation attribute information of the wheel grounding point, so that the vehicle detection method which is more universal and more suitable for various scenes is provided.
Description
technical field [0001] The present invention relates to the technical field of image detection, in particular to a vehicle detection method and device. Background technique [0002] In the current vehicle detection technology, the location of the vehicle in the image is generally identified in the form of a detection frame. [0003] However, in the current vehicle detection technology, it is not very suitable to identify the location of the vehicle in the image in the form of a detection frame, for example, in the vehicle detection scene of the fisheye image, the position of the vehicle in the fisheye image The distortion is large. If the position of the vehicle in the image is marked in the form of a detection frame, on the one hand, the detection effect is not good enough, that is, the position of the marked vehicle is not accurate enough; on the other hand, the detection frame on the fisheye image has been de-distorted And after projective transformation, it no longer ha...
