Problems solved by technology

Because there is directionality between the RF device and the tag during detection, the detection result is inaccurate when there is occlusion between the two. In addition, the RF device has a high operating frequency and a long transmission and reception distance. When there are adjacent objects under test, it cannot Correctly identify vehicle entry and exit
The third is image-based in-position and out-of-position state detection. This method uses the color model of the parking space and edge features for image analysis to achieve in-position and out-of-position state detection. However, the features used by this image-based method It is too simple and has poor anti-interference ability, so it is easy to be interfered and cause detection errors during detection, and it is impossible to accurately and timely detect the entry and exit of the vehicle

Abstract

The invention discloses a method and device for determining the entering of vehicles to parking spaces. The method includes the following steps that: the position information of targets in a video frame image of a parking lot is acquired, and the position information of the targets is compared with the position information of parking spaces; whether the position information of the targets and the position information of the parking spaces have intersections is judged; virtual loop detection is performed on the video frame image, whether the number of feature points is greater than a parking space entering threshold value is judged; vehicle detection is performed on the video frame image, whether the targets in the video frame image are vehicles is judged; and if the targets in the video frame image are vehicles, the corresponding vehicles in the video frame image are in parking space entering states. According to the method for determining the entering of the vehicles to the parking spaces, the parking space entering states of the vehicles can be identified accurately through three identification processes, and the information of the vehicles entering the parking spaces can be obtained in real time without increasing hardware cost. The invention also discloses a method and device for determining the exiting of vehicles from parking spaces. According to the method and device for determining the exiting of the vehicles from the parking spaces, the parking space exiting states of the vehicles can be identified accurately through three identification processes, and the information of the vehicles exiting from the parking spaces can be obtained in real time. The invention also discloses a vehicle management system.

Description

technical field [0001] The present invention relates to the technical field of image processing, and in particular to a vehicle in-position determination method and device, a vehicle out-of-position determination method, a device and a vehicle management system. Background technique [0002] At present, video technology has been widely used in parking lots, urban roads, expressways and other areas for automatic capture and recognition of vehicle information. With the continuous increase of the number of vehicles, the application of video technology in intelligent transportation will be more and more. Now the video-based road parking management system widely uses video technology to realize the management of parking spaces. However, there is a problem in the video-based road parking management system. After the vehicle enters the parking space, due to the limitation of the spatial position of the camera, some license plate information is blocked, and the camera cannot automat...
