Automatic parking space detection and identification system based on panorama visual assistance system

Abstract

The invention discloses an automatic parking space detection and identification system based on a panorama visual assistance system. The system mainly aims at solving the problems that in the prior art, since a parking space marking line is not complete and there is shade or an obstacle in the parking space, the parking space detection and identification are inaccurate. The system includes a camera detection module and an identification module, and cameras are installed around a vehicle to splice a seamless panorama image capable of reflecting the surrounding information of the vehicle; the detection module completes detection of a parking space marking line and completes the parking space detection according to the perimeter of the marking line under the situation that the parking space marking line is not complete; the identification module completes the parking space identification by calculating a difference value of the gray level change in the parking space and the height of an obstacle in the parking space under the situation that there is shade or the obstacle in the parking space, and the detection and identification results are displayed on a vehicle-mounted central control big screen. The automatic parking space detection and identification system achieves efficient and accurate detection and identification of the parking space, provides effective bases for route planning and route tracking control in later automatic parking, and can be used by a driver to find a parking position.

Description

technical field [0001] The invention belongs to the technical field of computer vision processing, and in particular relates to an automatic parking parking space detection and recognition system, which can be used for drivers to find parking positions. Background technique [0002] With the rapid increase of car ownership, the problem of "difficult parking" in urban scenes has become more and more prominent. When the driver is parking, due to the limitation of objective conditions such as narrow vision and parking spaces, as well as technical and psychological influences, it is very easy to have a collision accident and cause unnecessary losses. An effective parking assistance system can help the driver to complete the parking operation quickly and safely, and the automatic parking system can automatically complete the safe and accurate parking position without the driver's control. [0003] At present, the commonly used automatic parking space detection and recognition me...

Problems solved by technology

However, the current vision-based parking space detection and recognition methods only aim at the detection of marking lines of ground parking spaces in ordinary scenes, and ignore the parking space detection problems in complex situations such as obstacles, shadows, and incomplete marking lines in the target parking space. How to detect parking spaces more accurately and reliably in more complex scenarios is an urgent problem to solve the current traffic management
