Embodiment Construction

[0034] The present invention will be further described below in conjunction with the accompanying drawings. It should be noted that this embodiment is based on the technical solution, and provides detailed implementation and specific operation process, but the protection scope of the present invention is not limited to the present invention. Example.

[0035] This embodiment provides a parking space recognition method utilizing a look-around image, and the specific process is as follows:

[0036] S1. Image preprocessing.

[0037] S1.1. Under the existing surround view image, not all regions need to be processed. The central area of ​​the look-around image is the car image, which is meaningless in the subsequent processing and is only for aesthetics. Therefore, removing the information in this area can effectively reduce the amount of calculation for subsequent operations, and can also effectively improve the recognition rate of subsequent parking spaces. . Therefore, in thi...

Abstract

The invention discloses a parking space identification method using an all-around image. The method comprises the following steps of: firstly, preprocessing an all-around image, secondly, determining the position of a parking space corner point by adopting a double constraint condition of combining straight line detection with corner point detection, and finally, identifying the type and the position of a parking space by using a template matching method. According to the method, the error recognition rate of parking space recognition is reduced by means of double constraint conditions, and the method can be applied to advanced driving assistance systems such as automatic parking.

Description

technical field [0001] The invention relates to the technical field of parking space recognition, in particular to a parking space recognition method using a look-around image. Background technique [0002] In the case of existing surround-view images, only one constraint condition is used to identify parking spaces, which will cause misidentification and non-identification. There is an urgent need for a parking space recognition method that can improve the recognition accuracy to solve the above problems. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention aims to provide a method for recognizing parking spaces using surround-view images. [0004] In order to achieve the above object, the present invention adopts the following technical solutions: [0005] A parking space recognition method using a look-around image, the specific process is: [0006] S1, image preprocessing; [0007] S2. Determine the inflection point ...
