Abstract

Recently, many industries are using three dimensional scanning technology. As the performance of the 3D scanner gradually improves, a sampling step to reduce a point data or a remove step to remove a part determined to be noise are generally performed in post processing. However, total point data by long time scanning cannot be processed at once in spite of performing such those additional processes. In general, a method using a multi threaded environment is widely used, but as the scanning process work time increases, the processing performance gradually decreases due to various environmental conditions and accumulated operations. This paper proposes a method to initially remove point data judged to be unnecessary by calculating accumulated fast point feature histogram values from coming point data of the 3D scanner in real time. The entire 3D scanning process can be reduced using this approach.

최근 많은 산업체에서 3차원 스캐닝 기술을 활용하고 있다. 3D 스캐너의 성능이 향상됨에 따라 점데이터를 획득하면 후처리를 통해서 일정 비율만큼 줄이는 샘플링 단계를 수행하거나, 잡음이라고 판단되는 부분을 제거한다. 하지만, 이와 같은 추가과정 수행에도 불구하고 오랜 시간 동안 스캐닝하면 점데이터들을 한꺼번에 처리할 수 없다. 일반적으로 멀티스레드 환경을 이용하여 기획득된 점데이터를 먼저 처리하는 방식을 이용하지만, 스캐닝 프로세스 작업 시간이 증가함에 따라 다양한 환경 조건과 누적된 연산으로 인하여 점차 처리 성능이 낮아진다. 본 연구에서는 3D 스캐너로부터 실시간으로 들어오는 점데이터를 누적된 고속 특징점 히스토그램 계산을 이용하여 불필요하다고 판단되는 점데이터를 초기에 제거하는 방식을 제안한다. 이 방법을 이용하면 전체 3D 스캐닝 프로세스의 속도 향상을 가져온다.
