The invention relates to a vehicle positioning method and system for a fixed parking scenario. The method includes: a map obtaining step of obtaining, by a vehicle, a parking scenario map from a cloud according to a preset trigger condition; a first positioning step of obtaining first geographical position information of the vehicle based on a first marker in a fixed parking scenario, and matching the first geographic position information with the parking scenario map, so as to obtain a first vehicle pose of the vehicle in the parking scenario map; and a second positioning step of obtaining second geographical position information of the vehicle based on a second marker in the fixed parking scenario, and matching the second geographical position information with the parking scenario map, so as to obtain a second vehicle pose of the vehicle in the parking scenario map. According to the invention, planar and spatial positioning of the vehicle can be implemented, and accurate positioning and accurate navigation in a fixed parking scenario can be implemented.

The disclosure relates to a vehicle positioning method and system for a fixed parking scenario. The method includes: a marker detection step of detecting markers and identifying a pair of markers; a pose matching step of performing pose matching based on vehicle position information and the pair of markers; a non-pose matching step of performing non-pose matching based on the pair of markers, to obtain latest vehicle position information; and a position update step of updating current vehicle position information based on the latest vehicle position information obtained in the pose matching step or the non-pose matching step.

The invention relates to a parking spot detection method and system. The method includes: acquiring a parking lot image including one or more idle and occupied parking spots around a vehicle; inputting the parking lot image to a neural network model for image processing, to obtain center point coordinates and a center point probability of the parking spot, first coordinates and first corner point probabilities of four corner points, and offsets of the four corner points relative to the center point coordinates; calculating second coordinates of the four corner points based on the center point coordinates and the offsets of the four corner points relative to the center point coordinates; correcting the second coordinates of the four corner points by using the first coordinates of the four corner points, to obtain actual coordinates and actual corner point probabilities of the four corner points; and performing parking spot detection based on the center point coordinates and the center point probability, and the actual coordinates and actual corner point probabilities of the four corner points. According to the invention, the parking spot can be accurately detected.
