Embodiment Construction

[0042] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0043] A parking space state recognition device, through real-time monitoring of the parking space, obtains the occupancy state of the parking space, paints a white triangle block on the ground of the parking space, and uses technologies such as video signal collection, image signal processing and recognition to detect Whether there is a triangle in the picture collected by the camera, that is, whether the parking space is free. The device includes: the minimum system circuit board of a single-chip microcomputer, a signal acquisition and processing module and a communication module. The structural block diagram of the device is as follows: figure 1 shown;

[0044] The minimum system circuit board of the single-chip microcomputer includes the minimum system of the single-chip microcomputer and the input and output ports required for control. That is, t...

Abstract

The invention provides a device for identifying a parking space state and a method. A white block diagram is drawn on the ground of a parking space and a vision identifying signal for judging whether the space is occupied or not is provided. The system mainly comprises a singlechip minimum system circuit board, a signal collecting processing module and a communication module. By using the visual advantage of the invention, compared with a traditional parking space monitoring mode, dynamic image threshold computation and self-adaptation adjustment for a specific environment are designed; the device has an efficient judging mode; an idle state of the parking space can be judged within short time; and the invention can be used for enhancing the intelligent degree and the management level of a parking lot and obtaining higher economic benefit and good social benefit.

Description

technical field [0001] The invention relates to the fields of video monitoring and image processing, in particular to a parking space state recognition device and method. Background technique [0002] With the continuous construction of large parking lots, the intelligent management system of parking lots aimed at improving the operating efficiency of parking lots will also develop accordingly. For parking lot status monitoring, there are many implementation methods at home and abroad: ultrasonic parking space detection method, ground sensing coil detection method, infrared detection method and Doppler microwave method. However, these methods have limitations: Ultrasonic parking space detection is easily interfered by non-vehicle objects; the construction of the ground sense coil is complicated, and it is easy to cause damage to the road surface; the infrared detection device is expensive; the Doppler microwave method is difficult to detect stationary or low-speed vehicles ...
