Embodiment Construction

[0037] The present invention is further described below in conjunction with accompanying drawing.

[0038] The solution of the present invention is:

[0039] (1) Obtain the input; the input is the bird's-eye view video stream obtained in any form, and the bird's-eye view of the present invention is formed by splicing the fisheye camera video streams around the front, rear, left and right sides of the vehicle through de-distortion and inverse perspective transformation to imitate the top view The non-perspective and distortion-free image can clearly display the surroundings of the vehicle without dead angles, so it is also called the surround view image, hereinafter referred to as the surround view;

[0040] (2) Mark point detection; the input of the present invention is a look around, and mark point detection is performed on the look around image. First extract the features of the look-around, and then traverse the image one by one through the sliding window. For the tiles in...

Abstract

The invention discloses a parking lot detection method, which comprises the following steps that: (1) obtaining information around a vehicle as input; (2) carrying out mark point detection on the input obtained in the (1); and (3) through the mark point obtained in (2), realizing parking lot deduction. An experiment verifies that the algorithm disclosed by the invention can accurately judge a parking lot position in a round-looking image and can conform to real-time algorithm efficiency. The method has the function that a key step in the automatic parking scene of an automatic driving field gives the accurate position of the parking lot in a vehicle coordinate system. A purpose that the position of the parking lot can be detected through the own camera of the vehicle on the basis of no additional infrastructures is realized.

Description

technical field [0001] The invention belongs to the field of auxiliary parking for intelligent driving, and relates to a parking space detection method, in particular to a parking space detection method based on visual machine learning. Background technique [0002] Cars are the most widely used means of transportation today, and the number of cars is increasing day by day, and the automotive industry is not just satisfied with the status quo. After decades of development in the automotive industry, from the earliest drivability to today's professional discipline that integrates multiple complex technologies, the future will even develop towards unmanned driving. The so-called unmanned driving refers to the ability to start, drive and stop without a driver, bringing people a more intelligent and safe riding experience; while unmanned driving technology integrates automatic control, artificial intelligence, and visual computing. It is the product of the organic combination o...
