Research On Multi-dimensional Data Processing And 3D Reconstruction Of Imaging Laser Radar

Imaging Laser Radar is the product of Laser technique and Radar technique; it can provide gray information and 3D information of the model. The thesis focuses on multi-dimension data processing and 3D reconstruction in order to perform 3D image.The thesis divides into three steps: Firstly, focusing on the software design of USB2.0 interface in order to communicate with computer in high speed; Secondly, making use of Taubin filter so that the noise is gradually eliminated from the overall structure of the model, while the fine structure is preserved; Then, A simple algorithm for local interpolation of surfaces using normal vectors is proposed, taking Visual C++6.0 and OpenGL as a programming tool, so the 3D shapes of the model can be reconstructed.The experiment result shows that the USB2.0 interface has worked well and the average transfer speed reaches 5Mbyte/s, so it can meet the basic requirements for real time transfer of imaging laser radar; mean while, the 3D shapes of the model can be displayed in reality to some extent, and the method of data process could perform well in real time imaging.
