The importance of vision system in Robotics becomes more significant. Especially, in unstructured enviroments such as construction sites, the performance of vision system to recognize the surrounding environment is much lower than the level of tasks that robots can complete. With the help of commercialized 3D sensors, many robots utilize the 3D sensor as eyes, however, the accuracy and resolutio..

Depending on the applications of the 3D sensing, we need to customize 3D scanners. For example, the system in the figure achieves a speed of 3D sensing up to 10,000 Hz and sub-pixel error for studies of flapping bird or vibration in manufacturing. I can develop the system for each application, using CMOS / CCD cameras and different types of projection patterns (laser speckle pattern/ statistical..

Using structured light for 3D reconstruction is preferrable for high-accuracy and high-speed 3D model acquisition, since users can control the patterns (signal) to be projected on objects (Active method of 3D reconstruction). Main research focuses on the pattern algorithm development and mathematical analysis for the 3D result.
