구조화 조명 영상에 Dynamic Programming 을 사용한 신뢰도 높은 거리 측정 방법 = Robust Depth Measurement Using Dynamic Programming Technique on the Structured-Light Image

다국어 초록 (Multilingual Abstract)

An algorithm for tracking the trace of structured light is proposed to obtain depth information accurately. The technique is based on the fact that the pixel location of light in an image has a unique association with the object depth. However, sometimes the projected light is dim or invisible due to the absorption and reflection on the surface of the object. A dynamic programming approach is proposed to solve such a problem. In this paper, necessary mathematics for implementing the algorithm is presented and the projected laser light is tracked utilizing a dynamic programming technique. Advantage is that the trace remains integrity while many parts of the laser beam are dim or invisible. Experimental results as well as the 3-D restoration are reported.
