Abstract: The data post-processing and software development of the terrestrial laser scanning (TLS) technology is a key factor that constrains the further development of three-dimensional laser scanning technology. In this work, combined with the Oracle storage technology, PCL algorithm and OpenGL 3D display technology, a set of the TLS data processing system with point cloud storage, processing, display and query functions was developed preliminarily. The feasibility of the TLS data processing systems developed by the proposed three technologies in this paper and the robustness of the system functions was verified via the statue point cloud data scanned by RIEGL VZ-400 scanner, which provides useful reference for further researches on the development of TLS data processing system.

Key words: point cloud processing, system integration, Oracle, PCL, OpenGL
