Abstract
A 3D hand-held scanner using the structured lighting technique has been developed by the Smart Sensors & Analysis (SSA) research group at Philips Research Eindhoven. This thesis presents an embedded implementation of such a scanner. A translation of the original MATLAB implementation into the C programming language resulted in a speedup of approximately 15× when executed on a desktop computer. However, running the new implementation on an embedded platform increased the execution time from 0.5 seconds to more than 14 seconds. A wide range of optimizations was proposed and applied to improve the performance of the application. As a result, a final execution time of 5.1 seconds was achieved. In addition, a visualization module was developed to display the reconstructed 3D models using the projector integrated into the embedded device.
