Problems solved by technology

Because any small displacement will easily lead to the failure of the weight toll system, which will paralyze the entire toll system and cause huge economic losses to the toll station
[0006] 3. In rainy days, because the protective glass of the infrared light curtain is easily disturbed by rain, its transmission / reception direction and power are changed, resulting in the failure of the infrared car splitter

Embodiment Construction

[0030] Fig. 1 is a structural schematic diagram of the present invention. As shown in the figure, the video car splitter disclosed by the present invention is composed of a frame, a DSP image processor, and a video camera. The frame is composed of a base 1 installed on the ground and a support rod 2 connected with the base 1 . A DSP image processor 3 is installed on the support rod 2 . A video camera 5 capable of changing the shooting angle is also fixed on the support rod 2 through an adjustable positioner 4 . The video signal output end of the camera is connected with the video signal input end of the DSP image processor through wires, and the digital signal output end of the DSP image processor is connected with the weight toll system.

[0031] The video car divider of the present invention is installed on the side of the road to be detected or above the road, where it is not easy to be scratched by running vehicles. The video image of the passing vehicle is obtained thro...

Abstract

The invention discloses a video vehicle separation apparatus arranged on one side of the detected road or above highways, comprising a frame, a DSP image processor and a camera, wherein, the DSP image processor and the camera are fixed to the frame, a video signal output terminal of the camera is connected with a video signal input terminal of the DSP image processor, a digital signal output terminal of the DSP image processor is connected with a loading-based toll collection system. The invention acquires the video image of the passing vehicle by the camera, and uses the DSP image processor to process the obtained image in A/D transformation, image modification, module comparison, image edge processing, and background noise modification, then obtains the head and tail information of the vehicle to separate the vehicle and output the result of vehicle separation to the loading-based toll collection system. The video signal output terminal of the camera is also connected with a monitor in a monitoring room by a conductor to provide the function of spot monitoring. The invention is safe in use, reliable in working and powerful in function.

Description

technical field [0001] The present invention relates to a device for identifying vehicles running on highways, in particular, the invention relates to a device that can be widely used in expressway toll-by-weight systems and uses video technology to effectively identify toll vehicles Video splitter. Background technique [0002] At present, there are two main types of car-dividing identification devices used in road toll collection systems by weight: one is an infrared car-dividing device that uses infrared light curtain technology to realize car-dividing, and the other is an electric car-dividing device that uses electromagnetic induction coils to realize car-dividing. Magnetic induction coil splitter. Its working principle is: when the vehicle passes, it can achieve the purpose of dividing the vehicle by identifying the head-to-tail gap between the vehicles, and give the vehicle dividing signal. [0003] For the infrared splitter, the minimum splitting distance is ≥0.2 m...
