Embodiment Construction

[0038] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0039] Such as figure 1 As shown, the embodiment of the present invention provides a real-time parking space detection method at the vehicle end, comprising the following steps:

[0040] S1, acquiring images from four angles of front, rear, left, and right of the vehicle taken by four fisheye cameras around the vehicle.

[0041] Install four fisheye cameras around the car to record the specific location of the installation; calibrate the internal and external parameters and distortion parameters of the four cameras. If the coordinate system is established with the center of the vehicle as the coordinate origin, the specific installation coordinates (x, y, z) of the four cameras are recorded to facilitate the subseq...

Abstract

The invention relates to a vehicle end real-time parking space detection method and device. The method comprises the steps that images, shot by four fisheye cameras arranged around a vehicle, of the front, back, left and right angles of the vehicle are acquired; according to the distortion parameter of the fisheye camera, distortion removal is carried out on the shot image, and the image is converted into a top view image through inverse perspective transformation; according to the internal and external parameters of the four fisheye cameras, splicing the four top view images by using a feature matching method to form a complete look-around top view image; parking space marking is carried out on the all-round top view image, and then the image is sent to a detection model for training; and calling the trained detection model to carry out real-time parking space detection. The parking space detection method mainly solves the problems that an existing parking space detection method is poor in effect and poor in real-time performance, and the accuracy and the real-time performance of detection are greatly improved.

Description

technical field [0001] The invention relates to the technical field of high-precision map production, in particular to a method and device for real-time parking space detection at a vehicle end. Background technique [0002] In the field of automatic driving and high-precision map production, the detection of parking spaces is one of the most important technologies. At present, most of the common parking space detection methods have poor detection results and poor real-time performance. Contents of the invention [0003] Aiming at the technical problems existing in the prior art, the present invention provides a real-time parking space detection method and device at the vehicle end, which mainly solves the problem that the existing parking space detection method has poor effect and poor real-time performance, and greatly improves the Detection accuracy and real-time performance. [0004] The technical scheme that the present invention solves the problems of the technologi...
