Parking space detection method based on optical image

Abstract

The invention provides a parking space detection method based on an optical image. Firstly, according to an obtained real-time image, parking space rectangular frames with the needs of detection are artificially taken, and the image variance of each parking space rectangular frame is analyzed and is used as a basis of whether parking a vehicle at an initial frame parking space. For a subsequent video frame, through the modes of counting the variances of the parking space rectangular frames and the change value of a variance between frames and carrying out foreground detection, whether vehicle are parked in the rectangular frames is comprehensively decided. According to the method, the problem of inadequate supervision of the roadside chaotic parking can be solved, manpower and material resources are greatly saved, the parking space state information can be transmitted in real time, and a detection result is accurate.

Description

technical field [0001] The invention belongs to the field of image processing, and in particular relates to a parking space detection method based on an optical image, which is suitable for parking vehicle state detection on the roadside and in open-air parking lots. Background technique [0002] With the development of the economy, the rapid increase in the number of automobiles has led to the problem of parking difficulties. According to the research, about 30% of the traffic volume is currently caused by the search for parking spaces, resulting in huge waste. At the same time, the effective management of informal parking spaces on the roadside in various communities has also received extensive attention. In the context of this demand, a variety of automatic parking space management systems have appeared in the market, among which the automatic detection of parking spaces is the core technology that determines the performance of the system. [0003] The parking guidance s...

Problems solved by technology

However, ultrasonic detection requires the installation of detectors above each parking space, which is costly

[0004] The above parking space detection method needs to install corresponding equipment for each parking space to complete the real-time monitoring of the parking space. The construction is complicated, and it is difficult to repair once a problem occurs.
