为解决传统地质素描技术在隧道中施作效率低、数据不连续且原始数据难以再现的问题，采用基于kinect传感器和kintinuous算法的隧道岩体三维重建方法，基于物理模型试验，确定三维重建过程中光源、TSDF立方体等主要参数指标，将模型试验重建误差控制在1.9%~2.5%，并将该参数指标应用于现场试验，重建出良好的隧道三维模型。结果表明，该方法在重建模型的全局鲁棒性和细节还原方面较好，具有可视化程度高、数据连续性强、操作简易等优点，有效改善了传统地质素描对裂缝、结构面等数据记录不够准确和不完善的问题。

Aiming at the issues of low efficiency, discontinuity and difficulty of reproducing the original data of geological sketch in tunnel construction, the idea of threedimensional(3D) reconstruction of tunnel excavated rock mass combined kinect sensor with kintinuous algorithm is proposed. The method solves the storage format and integrityproblem of original data in the geological sketching process and improves the working efficiency of identifying geological attributes. Through the physical model tests, the parameters of the 3D reconstruction process of the tunnel are determined. The field test results shows that the method is better in the global robustness and detail reduction of the reconstruction model, and the error is controlledwithin 1.9%~2.5%. In short, the method has advantages of high visibility, strong continuity of data and simple operation, which can provide an efficient and accurate method for geological sketching of tunnel engineering, withwide range ofpromotional application value.
