The Design And Implementation Of Rock Mass Joint Statistical Scheme Based On Kinect

The statistical work of joints is the main content of geological surveying and map-ping in geological engineering,as well as the basic work of rock mass stability analysis.The existing rock mass joint measuring tools(such as geological compass,photogram-metry and laser measurement)are not suitable for joint statistics work of some adits with difficulty in directly entering and under illumination.In addition,the existing joint sta-tistical work is divided into two steps:rock jointing measurement and joint occurrence statistics.It is necessary to take rock jointing measurements first to obtain rock jointing data and then to make the joint occurrence statistics off line,and the efficiency is not high.Therefore,this paper designs and realizes the statistical scheme of rock jointing based on Kinect.By using Kinect and this scheme,the occurrence of rock joint sets can be obtained directly and accurately.The main contents of the thesis are as follows:Firstly,rock mass joint statistical scheme based on Kinect are analyzed and de-signed,and detailed analysis and selection are made for the acquisition method of rock surface point cloud,the method of obtaining joint surface appearance and the data ac-quisition method of joint sets occurrence data.Secondly,the prototype software of rock mass joint statistical program based on Kinect is implemented.The main interface of the software is realized by the Qt interface class library.The point cloud acquisition module of the rock mass surface is realized by the C++ and InfiniTAMv2 method.The rock jointing surface extraction module is realized by the C++ and the region growth algorithm.The statistical module of the jointed rock mass surface is realized by the Python and Exponential Kamb method.Thirdly,the prototype software is applied to the geological exploration adit on the bank slope of the right bank of the Laxiwa Hydropower Station,and the rock jointing statistical results of the prototype software in different rock mass surface scenes are analyzed.The results show that the proposed scheme is feasible.Based on the theory and method of computer vision and geology,this paper designs and implements a joint statistical scheme based on new tools.Through this scheme and prototype software,the data of rock mass formation can be obtained directly,and the accuracy of geological survey can be improved.
