A method, system and medium for identifying a parking area

Abstract

The invention provides a parking area identification device, identification method, system and medium, which adopts the structure of a feature point module, a pose calculation module, a distortion correction module, an absolute scale recovery module, a spatial point reconstruction module, and a parking area search module. The feature point module completes the feature point extraction and detection of the pictures taken by the camera. The pose calculation module calculates the pose relationship of the camera at the shooting time of the two frames of pictures. The distortion correction module performs distortion correction on the extracted fisheye feature points. The absolute scale recovery module uses The real camera height restores the real scale. The spatial point reconstruction module uses the camera pose and absolute scale to restore the value of the reconstructed point cloud. The parking area finding module finds the structure and method of the area that can be parked according to the reconstructed spatial point cloud. Solve the shortcomings of ultrasonic radar failure and the inability to obtain the actual scale based on the parking line detection method, and efficiently and accurately detect the parking area that meets the parking requirements for motor vehicles.

Description

technical field [0001] The present invention relates to the technical field of automobiles, in particular to a method, system and medium for identifying a parking area. Background technique [0002] With the advancement of science and technology and the development of society, people's living standards have gradually improved, and the number of motor vehicles has also increased rapidly. However, the technical problem of parking has always troubled most people. Therefore, the automatic parking function of motor vehicles has become more and more important. The most important, and a very important link in automatic parking is the detection of the parking area. [0003] At present, there are many methods for detecting parking areas, including methods based on physical feature detection such as buried induction coils, ultrasonic radar, and geomagnetic detection, as well as visual methods based on parking line detection. However, the former is cumbersome to construct and difficul...
