Title:
PARKING LOT DATA MATCHING METHOD AND APPARATUS, DEVICE, MEDIUM AND VEHICLE
Document Type and Number:
WIPO Patent Application WO/2024/060420
Kind Code:
A1
Abstract:
A parking lot data matching method and apparatus, a device, a medium, and a vehicle. The method comprises: randomly selecting, from parking lot traveling trajectories collected on multiple occasions, vehicle traveling trajectories collected on different occasions, taking one of the traveling trajectories as a current reference trajectory, and taking the other traveling trajectory as a current trajectory to be matched (S110); on the basis of alignment frames matched with vehicle poses in the current reference trajectory and the current trajectory to be matched, relative poses of trajectory frames to be matched, and an absolute position of a vehicle outside a parking lot, sequentially performing pose adjustment on the trajectory frames to be matched, and performing pose alignment on the pose-adjusted trajectory frames and a corresponding reference trajectory frame to obtain a current alignment result (S120); and returning to execute a matching operation between the current reference trajectory and the current trajectory to be matched until a predetermined number of parking lot traveling trajectory matching operations are completed (S130). Hence, the parking lot traveling trajectories collected on multiple occasions are quickly and accurately associated.
