Problems solved by technology

[0002] Parking spaces scattered on the roadside and in public places are difficult to centrally manage because there is no unified entrance and exit, and only special toll collectors can be assigned
Due to the nature of the work and the workplace, the work of the toll collectors is very hard, and it is urgent to adopt an unmanned method for management
In the practice of solving this problem, it is found that vehicles often do not park according to the designated area of ​​the parking space, such as the vehicle is not parked in the center, or the vehicle is skewed, which affects the use of the parking space next to it, and the vehicle is not completely parked. Affects safe driving in the outer lane

Embodiment Construction

[0015] The present invention will be further described below in conjunction with accompanying drawing:

[0016] refer to figure 1 -2. The parking fee system that can judge the effectiveness of vehicle parking is used to judge whether the position of the vehicle in the parking space is correct, so as to prevent the parking position of the vehicle from being out of the center in the unmanned parking space management, or the vehicle is skewed, which will affect the parking next to it. The use of parking spaces and vehicles not completely parked affect safe driving in the outer lane. The parking spaces are set as straight or inclined, and are distributed on the roadside or in public places.

[0017] A binocular stereo camera is set at the middle of the bottom of the parking space, and the binocular stereo camera is facing the entrance and exit passage of the parking space, and is used to shoot images after the vehicle enters the parking space. It can also be According to binocul...

Abstract

The invention discloses a parking charging system capable of judging parking validity of a vehicle. The parking charging system is used for judging whether the position of a vehicle parked in a parking space is correct or not, the parking space is arranged to be in a straight-entering or inclined-entering mode, a binocular stereo camera is arranged in the middle of the bottom of the parking space, and the binocular stereo camera directly faces an access channel of the parking space. The vehicle parking validity judgment method comprises the following steps that the stereo camera obtains an image pair fL(x, y) and fR(x, y) of the parking space, and depth information Z(x, y) is formed by taking the image fR(x, y) as a reference; a license plate area A is extracted in the image fR(x, y); a central line and a midpoint m of the license plate area A in the horizontal direction are extracted, and the position ZM and XM of a central point M of the license plate is calculated; an XZ coordinate of a point on a license plate center line LINE is calculated; the slope k of the license plate center line LINE on the XZ-plane is calculated by adopting a least square method; and when the central point M meets the following conditions: |x0 / 2+x1 / 2-M / 2|<TX; ZM<TZ; and |k|<Tk, the vehicle is judged to be parked effectively.

Description

technical field [0001] The invention relates to a parking charging system capable of judging the effectiveness of vehicle parking, and belongs to the technical field of intelligent parking charging. Background technique [0002] The parking spaces scattered on the roadside and in public places are difficult to centrally manage because there is no unified entrance and exit, and only special toll collectors can be assigned. Due to the nature of the work and the workplace, the work of the toll collectors is very hard, and it is urgent to manage them in an unmanned manner. In the practice of solving this problem, it is found that vehicles often do not park according to the designated area of ​​the parking space, such as the vehicle is not parked in the center, or the vehicle is skewed, which affects the use of the parking space next to it, and the vehicle is not completely parked. Affects safe driving in the outer lane. Due to the need to assist in detecting the validity of th...
