Research On Detection And Distance Measurement Technology Of Moving Target In Video Image

In recent years, the researchers in information are interested in an subject which is machine eyes instead of man eyes. A whole traffic managerment system is consisted of three parts one is getting image and preprocessing, the other is comfirming position of cars from a complex background, the last is cars'charactics being collected.On the basis of digital image processing application of the theories and methods, research and analysis of the digital image pre-processing graphics goals Detection and Ranging model approach, based on the construction of a digital image processing operation of the single-head camera at the location opposite the programme. Aimed at adoption of the single-head camera captured images of a series of treatment, access to information from the front aims and the single-head camera. Firstly, the graphics on the moving target image pre-processing, and image of the target color space transform graphical location detection; Secondly, using edge-enhanced image with the Hough transform graphics target feature extraction, in accordance with the objectives of objects detected in the border, pixels calculated using statistical method to calculate the target area of the real-time graphics area, calculated in accordance with the objective of changing the size of graphics area ranging derived formula, the achievement of distance measurement; Finally, the use of computer language structures ranging trial procedures, through the range trial program to capture images for processing, access to location results and the actual distance are compared and analyzed.In this paper, moving target with the range betweet the cemera date in the imitative video monitoring system is developed VC++ 6.0 and Matlab. Through the test data and image analysis, the method of distance measurement is single, effective and aviable run-time of vehicles ranging opposite approach.
