The invention discloses a vehicle lane change detection method and device, particularly relates to artificial intelligence, and further relates to the technical field of intelligent transportation and image processing. The specific implementation mode comprises the steps of conducting object detection on a vehicle image collected by a camera, and obtaining two-dimensional vehicle information of a vehicle in the vehicle image; determining three-dimensional vehicle information corresponding to the two-dimensional vehicle information through a ground equation and parameters of the camera; and in response to the satisfaction of the detection condition, determining whether the vehicle changes lanes based on the lane position information and the three-dimensional vehicle information in the high-precision map, and obtaining a lane change detection result. Through the three-dimensional vehicle information, the problem of lane misjudgment caused by a large shooting angle of a two-dimensional vehicle image in the prior art can be solved, and the accuracy of vehicle lane change detection is effectively improved. And meanwhile, by utilizing the high-precision map, the accuracy of acquiring the lane position information is improved, and the accuracy of detecting the lane change of the vehicle is further improved.
