Embodiment 1

[0046] Such as figure 2Shown, shown in embodiment 1 of the present invention comprises the following steps:

[0047] S1. Install fisheye cameras in four directions: front, rear, left, and right;

[0048] S2. Collect images from fisheye cameras in four directions, front, rear, left, and right of the vehicle, and convert them into a top view centered on the vehicle position. This process is realized through projection transformation and splicing operations of the surround-view images.

[0049] S3. Input the top view into the parking space detection module based on the graph neural network, detect the four corner positions of the parking space in the image, and identify the parking space type;

[0050] S3.1. For each frame of top view, it is first scaled to a standard size of 600x600 pixels.

[0051] S3.2. Input the image data in S3.1 into the image encoder of the parking space detection module based on the graph neural network, and output the image feature F; input the image ...

Abstract

The invention belongs to the technical field of automatic driving, and specifically provides an automatic parking parking space detection method based on a graph neural network. Install image acquisition equipment in the four directions of the front, rear, left, and right of the vehicle; use the image acquisition equipment to collect images in the four directions of the vehicle, front, rear, left, and right and convert them into a top view centered on the vehicle position; input the top view into the parking space detection module based on the graph neural network, and detect The four corner positions of the parking space in the image, and identify the type of parking space; send the detected parking space information to the planning control module, calculate the parking route and control the vehicle to automatically drive into the detected target parking space to realize automatic parking . The automatic parking space detection method based on the graph neural network of the present invention can obtain the precise location of the parking space only by relying on the image data captured by the surround-view camera. The parking position of the parking vehicle is judged, and the detection accuracy is high.

Description

technical field [0001] The invention belongs to the technical field of automatic driving, and in particular relates to an automatic parking parking space detection method based on a graph neural network. Background technique [0002] Automatic parking based on computer vision is an important application of driverless driving. Compared with manual parking, automatic parking technology has more precise parking path and simpler parking operation, which can reduce scratches and collisions caused by manual operation errors, making the parking process safer and more efficient. [0003] Parking space detection based on ultrasonic radar detection is a mature and widely used technology. Detection based on ultrasonic radar relies on other vehicles around the target parking space. When there are no referenced parking vehicles around the target parking space, the target parking space cannot be effectively identified. Even if there is a reference parked vehicle, the position of the aut...
