Embodiment Construction

[0048] Below by embodiment the present invention will be further described, and its purpose is only to understand research content of the present invention better but not limit protection scope of the present invention.

[0049] Such as figure 1 Shown is a flowchart of a parking space detection method according to an embodiment of the present invention, including the following steps a~e.

[0050] Step a: Obtain a bird's-eye view of all parking spaces around the vehicle. The bird's-eye view is formed by splicing four fish-eye images around the vehicle, and attaching the top view of the vehicle to the center of the spliced ​​fish-eye image.

[0051] Step b: mark four vertices for each parking space in the bird's-eye view, and define the sequence of the four vertices of the parking space. The order of the four vertices of the parking spaces is: left front (1), right front (2), right rear (3), left rear (4), with the parking entrance and exit as the front direction. The four ve...

Abstract

The invention provides a parking space detection method, comprising the following steps: Step a: Obtain a bird's-eye view of all parking spaces around the vehicle; Step b: Mark four vertices for each parking space in the bird's-eye view, and define four parking spaces the order of vertices; step c: set up a parking space detection model, step d: carry out model training, obtain the trained parking space detection model; and step e: send the bird's-eye view to be measured into the well-trained parking space detection model for parking Detect and obtain the parking space category, parking space location and its centrality, so as to obtain the final parking space. The present invention has the following beneficial effects: on the same basis of achieving real-time, the method of the present invention directly detects parking spaces in one step without matching and inferring according to preset rules, so the method of the present invention is more direct and effective, and is applicable to more types of parking spaces .

Description

technical field [0001] The invention relates to the field of machine vision, in particular to a parking space detection method. Background technique [0002] At this stage, artificial intelligence technology continues to mature, automatic driving and assisted driving technologies are also widely developed and commercialized, and the majority of users also have urgent needs for assisted parking and automatic parking. In addition to driving on the road, the vehicle also needs to drive into the corresponding parking space, which requires precise positioning of the parking spaces near the vehicle in order to plan the parking route and park the car safely and accurately. Most of the existing vehicles are equipped with a panoramic monitoring image system, which can establish a bird's-eye view through the on-board vision system, so as to locate nearby parking spaces on the bird's-eye view, so that the subsequent control module can control the vehicle to drive into the parking space...
