Embodiment Construction

[0038] The present invention will be described in detail below in conjunction with the accompanying drawings and examples.

[0039] The method of the invention is divided into two parts: off-line setting and on-line monitoring. Such as figure 1 As shown, in the offline setting, based on the single photo of the roadside parking lot, manually circle the corresponding irregular area for each parking space and assign a unique parking space number; At time t, an image is collected and sent back to the control center through the wireless network, and then the state of the parking space is detected. The detection process first performs preliminary processing on the image to obtain the edge image of the image; then obtains the corresponding area of ​​the edge image according to the predefined area template and cuts it out; then judges whether it is an empty parking space based on the irregular area; finally records according to the state change of the parking space The current parki...

Abstract

The invention discloses a roadside parking intelligent monitoring method on the basis of vacant parking space image detection. The roadside parking intelligent monitoring method includes an offline setting portion and an online monitoring portion. Corresponding irregular regions are enclosed for each parking space in manual modes on the basis of photographed single-frame photos of roadside parking places during offline setting, and unique parking space numbers are attached to the irregular regions; an image is acquired by a camera at the intervals of a time period t during online monitoring, the images are fed to control centers via wireless networks, and then states of the parking spaces are detected. The roadside parking intelligent monitoring method includes preliminarily processing the images in detection procedures and acquiring edge graphs of the images; acquiring corresponding regions of edge images according to predefined region templates and clipping the corresponding regions; judging whether the parking spaces are vacant parking spaces or not on the basis of the irregular regions; recording current parking space states and parking start time and end time of the parking spaces according to change of the states of the parking spaces.

Description

technical field [0001] The invention belongs to the field of computer vision technology and image detection technology, in particular to an intelligent monitoring method for roadside parking based on image empty parking space detection. Background technique [0002] For car owners who park for a short time, on-street parking is the best choice. Detecting the parking state of the parking space is an important means to improve the coordination of parking space management, parking guidance, and reasonable scheduling. The number of parking spaces in a roadside parking lot generally ranges from 10 to 50. Through parking space detection, on the one hand, the LED display screen of the base station can be induced to display the current free parking spaces in real time to improve the efficiency of car owners in finding suitable parking spaces; on the other hand On the one hand, it can solve the related problems of on-street parking charges, such as the timing basis of on-street park...
