Embodiment 1

[0047] figure 1 A schematic diagram of the parking space state detection process provided by the embodiment of the present invention, the process includes the following steps:

[0048] S101: Acquire a fisheye image captured by a fisheye camera, and perform correction processing on the fisheye image to obtain an image to be detected.

[0049] S102: Input the image to be detected into a pre-trained vehicle detection model, and determine coordinate information of each vehicle in the image to be detected based on the vehicle detection model.

[0050] S103: Obtain the coordinate information of the parking space area of ​​each parking space in the image to be detected, and determine whether there is a vehicle parked in each parking space according to the coordinate information of each vehicle and the coordinate information of the parking space area of ​​each parking space .

[0051] The parking space state detection method provided by the embodiment of the present invention is app...

Embodiment 2

[0057] In order to make the determination of the image to be detected more accurate, on the basis of the above embodiments, in the embodiment of the present invention, performing correction processing on the fisheye image to obtain the image to be detected includes:

[0058] Correction processing is performed on the fisheye image to obtain a first candidate image, and segmentation processing is performed on the first candidate image according to a preset segmentation rule to obtain each image to be detected.

[0059] In the embodiment of the present invention, after the fisheye image is corrected, the obtained image is called the first candidate image, and then the first candidate image is segmented according to the preset segmentation rule, and each obtained after the segmentation process is sub-images are used as images to be detected. Wherein, the preset segmentation rule may be to divide the first candidate image into four to obtain four images to be detected, namely upper...

Embodiment 3

[0066] In order to improve the experience of the driver entering the parking lot, on the basis of the above-mentioned embodiments, in the embodiment of the present invention, the method further includes:

[0067] According to whether there is a vehicle parked in each parking space, the number information of the occupied parking spaces and the number information of the vacant parking spaces are counted, and the prompt information carrying the number information of the occupied parking spaces and the number of vacant parking spaces is output.

[0068] The electronic device counts the information on the number of occupied parking spaces and the number of vacant parking spaces according to whether there are vehicles parked in each parking space, and then outputs prompt information, wherein the prompt information carries the information on the number of occupied parking spaces and the number of vacant parking spaces. In the embodiment of the present invention, a display screen may b...

Abstract

The invention discloses a parking detection method and device based on a fisheye camera, equipment and a medium, and the method comprises the steps: obtaining a fisheye image collected by the fisheyecamera, and carrying out the correction of the fisheye image, and obtaining a to-be-detected image; inputting the to-be-detected image into a pre-trained vehicle detection model, and determining coordinate information of each vehicle in the to-be-detected image based on the vehicle detection model; and acquiring parking space area coordinate information of each parking space in the to-be-detectedimage, and determining whether a vehicle is parked in each parking space according to the coordinate information of each vehicle and the parking space area coordinate information of each parking space. According to the embodiment of the invention, vehicle detection is realized based on the pre-trained vehicle detection model, the influence of environmental factors is small, and the detection accuracy can be ensured even in a poor environment.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a parking detection method, device, equipment and medium based on a fisheye camera. Background technique [0002] In the indoor parking lot, the parking detection is generally carried out through a monocular camera or a binocular camera, and the vacant parking space and the occupied parking space are determined through the parking detection. Monocular cameras generally can only detect two to three parking spaces, and binocular cameras generally can only detect four to six parking spaces. The number of parking spaces detected is limited, so the number of monocular cameras or binocular cameras that need to be deployed in the parking lot is large. Increased costs. In addition, when performing parking detection in the prior art, it is generally determined whether there is a vehicle parked by the confidence of the license plate recognition in each parking space. If t...
