Vehicle detection method, device, equipment and medium

The embodiment of the invention discloses a vehicle detection method, device and equipment and a medium. The method can be applied to scenes such as ports, expressways, logistics, mines, airports, ports, closed parks or urban traffic. The method comprises the following steps: inputting a target image into a first network for feature extraction to obtain image features; and performing feature recognition on the image features through a second network to obtain a detection result whether the target image contains the to-be-detected vehicle or not. According to the method, the self-encoder with the mask function is added in the training stage of the first network, so that the network can extract the overall description of the image in limited input, and then the network has better deep semantic feature extraction capability. And the training sample of the second network is determined according to the feature extraction result of the first network on the input image, so that the network can effectively extract th
