Embodiment Construction

[0030] Embodiments of the present invention: the comprehensive application method of highway tunnel driving image acquisition information, a plurality of detection points are set in the highway tunnel, and infrared cameras are installed at each detection point to collect the video information of passing vehicles, and then the collected Perform image processing on the video information to obtain feature information of the image, the feature information includes whether there is a car passing the detection point, the number of incoming cars, and the fastest driving speed of the incoming car; this data is used as the brightness adjustment of the LED tunnel light control parameters.

[0031] The image processing of the collected video information specifically includes the following steps:

[0032] 1) Preprocessing of the vehicle image: After the image is grayscaled, denoise the grayscaled image to obtain a preprocessed image; the quality of the image collected by the camera will b...

Abstract

The invention provides a comprehensive application method of expressway tunnel driving image acquisition information. video information is acquired by infrared shooting, changes in tunnel driving images and their backgrounds caused by lighting of different lamps can be maximally avoided, difficulty of late image processing can be reduced, feature information of the images is acquired by subjecting the acquired video information to image processing, and finally the feature information is encoded as a control parameter to adjust LED tunnel lamp lighting brightness. The method has the advantages that accuracy is high, tunnel lamps are turned on when vehicles get close and are turned off when the vehicles leave, and energy is effectively saved at the premise of ensuring tunnel driving safety; during detecting the tunnel vehicle information by image analysis, information output through the method necessarily include speeds of vehicles at a monitoring site, quantity of the vehicle, passing time, feature images, vehicle types, license plates and the like, the information is stored, traffic police officers are assisted by data mining in looking into violations of laws, assisting the criminal police in querying the information of suspects, including the time of their vehicles passing a tunnel and the license plates.

Description

technical field [0001] The invention relates to the technical field of road lighting, in particular to a method for comprehensive application of driving image collection information in expressway tunnels. Background technique [0002] In the operation of the expressway tunnel lighting intelligent control system, the accurate detection of the number of vehicles passing through the tunnel node and the speed of the fastest vehicle is to realize the tunnel "vehicle approaching light is on, vehicle passing light is off, and appropriate lighting is provided according to the speed of the vehicle", ensuring the tunnel The key technology for effective energy saving under the premise of driving safety. The primary goal of the intelligent lighting control system is to ensure safe driving in the tunnel, followed by energy saving. Accurately judging the incoming vehicle information is very important. At present, methods such as geomagnetic method, infrared radiation, ultrasonic wave, an...
