Problems solved by technology

In the prior art, parameters such as panoramic picture data and traffic flow are transmitted separately in bitmap format and ASCII code files; in 24-hour uninterrupted monitoring, these tens of thousands of image data and traffic flow and other parameters often form transmission traffic Load conditions that are large and occupy a large storage space

Embodiment Construction

[0022] From figure 1 figure 2 It can be seen that the present invention is different from the prior art in that, compared to the original image data acquisition module, video detection module, JPEG compression module, and data upload module, functional modules such as image data parameter data mixing modules are provided. The image data parameter data mixing module is mainly realized by the following key steps: First, the bitmap collected by the image data acquisition module is scanned horizontally (X-axis) and vertical (Y-axis) to find the point where the grayscale is close to a certain value, namely Read the image bitmap and call the grayscale analysis function, find out the X and Y values ​​corresponding to the fixed grayscale values, and convert them into a two-dimensional array; the second is to encode the traffic flow and other parameters to form a two-dimensional array, and the third is to read Two-digit array, find the interpolation coordinates, if there is no interpolat...

Abstract

The invention discloses an image data parameter data mixing method based on electronic polices, relates to the field of an intelligent traffic system control technology, especially a mixing-processing technology for a police grasp shooting image data traffic parameter of an illegal vehicle. The invention is characterized in that, an image data collecting module, a video detecting module, a JPEG compressing module, a data uploading load, and an image data parameter data mixing module are provided, mixing-compression is performed on the image parameter data before transmission by the mixing module, decompression and separation are performed on the data after transmission by a separation module. During traffic flow monitoring parameter transmission, bit flow is effectively used, information amount transmission is expanded, loading situation that large image data parameter transmission flow occupies large storage space is improved, meanwhile the information amount is enlarged, and function is expanded without changing the hardware system.

Description

Technical field [0001] The invention relates to the technical field of intelligent traffic system control, in particular to a hybrid processing technology for electronic police to capture image data of illegal vehicles. Background technique [0002] In the field of urban intelligent transportation system control technology, intelligent transportation information statistics system and electronic police law enforcement punishment system are two important components. Among them, the traffic information statistics system can timely and accurately collect and count the road condition information of a large range of highways. The information parameters include road occupancy, traffic density, fleet length, circulation, average speed, etc., which can provide powerful road guidance The electronic police enforcement punishment system can accurately, stably, automatically, all-weather monitoring, enforcement and punishment of a series of violations such as speeding, retrograde, red light r...
