A fixed-point directional parking system for shared electric motorcycles

Abstract

The present invention discloses a shared electric motorcycle fixed-point directional parking system, which relates to the technical field of fixed-point directional parking. The present invention adopts a GPS signal quality detection mechanism, calculates the variance of GPS data through multiple sampling, evaluates positioning accuracy, directly adopts GPS positioning if the signal is stable, otherwise calls UWB for position correction, and adopts a weighted fusion algorithm to calculate the final position information, thereby improving the stability of vehicle positioning; a polygonal enclosing algorithm and Euclidean distance calculation are adopted in parking area matching to ensure that the vehicle parking position is compliant, and by setting a parking area tolerance range, effectively filters out misjudgments that may be caused by positioning errors; in terms of directional parking, an ultra-wide-angle camera is installed in the parking area, and the parked vehicle is visually identified in combination with an edge computing unit, and the vehicle's main direction angle is calculated using the minimum circumscribed rectangle method. At the same time, in combination with an IMU sensor and an electronic compass, the posture information and magnetic azimuth are calculated to ensure that the vehicle is parked in a preset direction.
