The Study Of Slope Displacement Detection Method Based On Image Recognition

SideSlope safety is not only related to Traffic Safety and people’s lives andproperty safety, but also the question of national economic interests.Once occur slopedisasterthe consequence is very serious. Deformation is the most significantparameterof slope conditions and the most to be able to reflect the change of slope situation andthe development tendency. If we can detect slope displacement accurately and forecastthe unknown deformation of slopes, the disaster prevention measures and will be takenas soon as possible. Made this kind of calamity loss will be reduced to lowest extent.Atpresent, in the field of slope safety testing, there are two kinds of testing method whichbase on stress and displacement. The testingmethods that bases on stress, like Sensormethod, exist some weakness like high level of specialization and high professionalrequirements. The testing methods which bases on displacement, like GPS andArtificial site method, all exist some weakness in different degree, like high level ofspecialization, high 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 detection method ofslope displacement which bases on Image Recognition Technology. I carry out thefollowing three aspects of work in this paper:First,Slope displacement field design: we set twokinds of target bodies in theslope,one is a anchor point, another is a monitoring point.Then we can use thevariation of displacement array to characterize the displacement of the slope.Second, The detection and recognition of target bodies:use image processingtechniques to analyse-process slope image.Toachieve the target identificationaccurately and extract the center coordinate values by use the recognition model. In thetargets detection,compared with the advantages and disadvantages of the commonlyused method, we launched a new algorithm for the research. This algorithm has high efficiency and reliability.it fit the quality of real time and accuracy which intelligentdetection system requires.third,three dimensional calculating of target parameters: when get the centroid,area of the target projection matrix, we can calculate the parameters of camera distancematrix, observation identification and location identification projection distance matrix,depth difference matrix by using the relationship of pinhole projection. Then take thespace three scaling method tocomplete the calculation of displacement matrix spacedata, so as to realized the conversion of two dimensional coordinates to threedimensional coordinate.
