Autonomous parking system and method based on cloud sharing and map fusion

Abstract

An autonomous parking system and method based on cloud sharing and map fusion, which adopts tracking-based autonomous parking as a whole, and only performs local path planning, which solves the problem that the current global path planning method requires high computing power and low real-time performance. Poor problem; track map sharing, track map selection, and track map fusion are carried out in the cloud, so that there is no need to build maps by yourself, and only need to select and reuse track maps according to GPS coordinates, scene semantic information, track label classification, etc., optimized Tracking route; establish a cloud-vehicle-user terminal collaborative communication mechanism, use the cloud to save, process and reuse maps, reduce the storage performance requirements of the car-end hardware, and at the same time, the real-time communication between the car end and the user terminal, The real-time and reliability of autonomous parking are guaranteed. The parking method is efficient in parking and has a high success rate.

Description

Technical field [0001] The present invention relates to the field of autonomous parking technologies in the unmanned industry and computer visual technology, which relates to autonomous parking systems and methods based on cloud sharing and map fusion, in particular to long-distance tracing parking technologies. Background technique [0002] In recent years, automatic driving technology has developed rapidly, and its own parking needs are getting wider and wider. Independent parking refers to a vehicle automatic parking instead of artificial intervention. Independent parking can provide users with secure, convenient, timeless parking service. Since the parking space in large cities is limited, on the one hand, the space to enter the small space has become a must-have skill, however, even if the driver is parked in the parking space, there is often due to the position of the position and cannot be opened. The road disorder of the three-dimensional garage causes the passenger to ge...

Problems solved by technology

[0015] 1. For the existing memory parking system, only the map created by oneself can be used. Its cloud system only has the function of temporarily storing its own trajectory map. The characteristic data of the surrounding environment used for trajectory and positioning, and the technical problem of insufficient positioning accuracy, this disclosure adopts the technical solution of sharing the trajectory map on the cloud to overcome the technical problems of the existing technical solution that the trajectory cannot be shared and the positioning accuracy is not high
