The Study Of Slope Displacement Detection Method Based On Image Processing

Our country is a mountainous country, and one of the landslid-frequent countries inthe world. Landslide has direct or indirect harm to the economic construction and socialdevelopment of human society, and it causes great damage to people’s lives andproperty. The detection of slope disasters is an important method to avoid or reduceharmness. At present, in the field of slope safety testing, there are two kinds of testingmethod which base on sterss and displacement. The testing methods that bases on stress,like Sensor method, exist some weakness like high level of specialization and highprofessional requirements. The testing methods that bases on displacement, like GPSand Artificial site method, all esist some waekness in different degree, like high level ofspecialization, hige cost and danger.With the continuous development of computerscience and mathematics, the technique of digital image processing has made greatstrides in development. Take advantage of image processing technology to analyse theshot digital picture, we can detect and measure interesting objectives in it, so that wecan meet the demand of displacement measurement. Compare with the traditionaldisplacement measure method, this method has the advantages of security, low cost,quick, reliable, etc.Based on the above discusses, this article has put forward real-time detectionmethod of slope displacement which bases on Image Processing Technology and VideoProtection Technology. Through this method, we set several target bodies in the slope,then we can use the variation of displacement array to characterize the displacement ofthe slope, and use image processing techniques to analyse-process slope image(Theimages come from the scene of the slope real-time streaming video), so that we can getthe displacement value of the slope. On the other hand, in the process of recognisingtarget body, this article has come up with the automatic identification method as well asthe center point measurement methods of the target body. In the end, this artical hasresearched and designed the slope displacement detection system, used MFC to havedeveloped parts of the main function modules, which can not only estimate slopedisplacement timely, but also has the function of real-time video by slope video andgive an alarm. Real-time video can reduction the real-time situation of the slope, and itis useful to inquire the cause of the slope disaster. The function of alarming can help to conduct rescue operation when disasters occur, and it contribute to reduce the loss to aminimum level.
