Problems solved by technology

However, there are many problems in this solution. For example, the traditional ultrasonic radar is generally installed at the rear of the vehicle, and the vehicle needs to drive through the parking space for identification, and the traditional ultrasonic radar cannot detect low objects with small cross-sectional areas in the parking space. , such as road cliffs, utility poles, etc., causing errors in the judgment of obstacles, resulting in parking problems

Embodiment 1

[0039] As an important part of vehicle driving, parking is a relatively complicated link for drivers, especially novice drivers. It is difficult for drivers to observe the situation of parking spaces directly and carefully while sitting in the car, so assistance is needed. The device helps to detect the situation of the parking space and judge whether it is possible to park. The existing detection method using ultrasonic radar has the disadvantages of being unable to detect obstacles with small cross-sectional areas and unable to judge the position of low road cliffs. Therefore, it is necessary to provide a method that can accurately detect all obstacles in vacant parking spaces for Detection of parking spaces.

[0040] refer to Figure 1~6 As shown, this embodiment provides a roadside parking space perception method based on a vehicle camera, specifically, including the following steps,

[0041] The acquisition module 100 collects the image of the rear vehicle and inputs it...

Embodiment 2

[0086] refer to Figure 8 To illustrate, this embodiment proposes a vehicle-mounted camera-based roadside parking space perception system, and the above-mentioned vehicle-mounted camera-based roadside parking space perception method can be implemented relying on this system. The system includes an acquisition module 100, an identification module 200, a computer vision module 300, a detection module 400, and a vehicle-mounted computing terminal 500, wherein the acquisition module 100 is used to collect data on the surrounding environment of the vehicle, and the identification module 200 can analyze the vehicle surroundings collected by the acquisition module 100. The environment data is recognized and processed. The computer vision module 300 is used for converting pixel coordinates and world coordinates and drawing a reference car frame. The detection module 400 can perform rough inspection and fine inspection of parking spaces, and judge whether parking is possible.

Abstract

The invention discloses a roadside parking space sensing method and system based on a vehicle-mounted camera. The roadside parking space sensing method comprises the following steps that a collectionmodule collects a rear vehicle image and inputs the rear vehicle image into an identification module, and the identification module carries out the identification of the rear vehicle image based on adeep learning method, outputs the pixel coordinates of a wheel, and transmits the pixel coordinates to a computer vision module; and the computer vision module converts the pixel coordinates into world coordinates and draws a reference line and a reference vehicle frame, inputs the reference vehicle frame into a detection module, judges whether parking can be carried out or not through rough detection and fine detection, and marks a parking space frame. The roadside parking space sensing method has the advantages that based on the vehicle-mounted camera, deep learning and computer vision are adopted to identify roadside parking spaces, and obstacles, especially low or small obstacles, in idle parking spaces can be accurately detected, and safety is improved.

Description

technical field [0001] The present invention relates to the technical field of image recognition processing, in particular to a roadside parking space perception method and system based on a vehicle camera. Background technique [0002] In recent years, more and more equipment and technologies have been applied to vehicle driving to increase driving comfort and safety, and parking (parking) is an important part of the technical field related to car driving. Accurate identification of road Whether there is a parking space available for parking is the basis for realizing safe parking. [0003] In the recognition of parking spaces, the most important part is to identify whether there are obstacles that affect parking. At present, in the detection of parking spaces, ultrasonic radar solutions are mainly used. Ultrasonic radar uses sound waves to locate and measure the distance of obstacles ahead. Thereby further judging whether the parking space can be parked. However, there a...
