Problems solved by technology

[0004] 1. Due to the different driving skills of each driver and the vertical position of the cab, there is no guarantee that each driver can park the car at a position where the arm can easily press the button to get the card. Some drivers need to get out of the car to get the card, which will affect the traffic efficiency
[0005] 2. Even though multiple bayonet slots are used, the model identification is inaccurate, resulting in wrong selection of bayonet bays

Embodiment Construction

[0028] The purpose of the present invention is to provide a vehicle window position recognition method to solve technical problems such as the low efficiency of the current card issuing system at the entrance of a road or parking lot, inability to facilitate the driver to take the card, and inaccurate selection of the card issuing window.

[0029] Such as figure 1 As shown in a and 1b, the automatic card issuing system at the entrance of the highway is composed of a laser distance measuring device (1), an artificial target (3), a virtual trigger line (5), a snap camera (2) and a card reader (4) located above the entrance )composition. The card removing machine includes a high bayonet outlet (41) on the upper part, a low bayonet outlet (42) on the middle part, an active infrared detector (44) on the top and a laser distance measuring device (43) on the lower part.

[0030] Combine below figure 2 , the working flow of the vehicle window position recognition method in the pres...

Abstract

The invention relates to a vehicle window position identification method. The method comprises the following steps: judging the height of a motor vehicle through phase delay variation of laser ranging; carrying out processing analysis on acquired vehicle image data to obtain a position parameter of the lower edge of a front windshield; acquiring the height and the position of a cab of the motor vehicle; according to the height of the motor vehicle, the position of the lower edge of the front windshield and the height and the position of the cab of the motor vehicle, calculating the position of a window of the vehicle. According to the vehicle window position identification method, an edge image of an original image can be more accurately determined through an improved algorithm and the position of the window of the motor vehicle can be accurately calculated, so that traffic capacity of a lane is improved.

Description

technical field [0001] The invention relates to a vehicle identification algorithm, in particular to a vehicle window position identification method. Background technique [0002] With the rapid development of domestic expressways and the increasing number of motor vehicles, people have put forward higher requirements for the efficiency of expressway traffic, and an intelligent expressway toll system has emerged as the times require. Expressway toll collection systems have come a long way from fully manual manual toll collection systems to the increasingly popular Electronic Toll Collection (ETC) system. For motor vehicles that have not applied for an ETC pass card or occasionally use the expressway, using an automatic card issuing machine on the expressway is undoubtedly an effective way to improve traffic efficiency. [0003] But there is following shortcoming in the automatic card issuing machine that often uses on the market at present: [0004] 1. Due to the different...
