Making a model that is an accurate replica of the oral structure requires precision and efficiency. Nowadays, rapid technological advances bring digitalization in dentistry. One of the most important works in digital dentistry is three-dimensional modeling of the oral cavity and digitizing the 3D da...

삼각법은 무엇인가? | 삼각법이란 물체의 형태에 대한 3차원 데이터를 모아 3차원 모델을 만드는데 사용되는 비접촉성 기술 중 하나이다.1 수동적 삼각법과 능동적 삼각법이 있고 모두 사용된다. | |
능동적 삼각법은 어떻게 물체의 위치를 계산하는가? | 1 수동적 삼각법과 능동적 삼각법이 있고 모두 사용된다. 먼저 능동적 삼각법은 빛을 직접 방출하여 물체의 표면에 투영하고 그 반사된 빛을 다시 수집하여 목표 물체의 위치를 계산해 낸다. 반면 수동적 삼각법에서는 스캐너에서 직접 빛을 방출하지 않고 반사된 주위의 빛을 탐지해 낸다. | |
수동적(passive) 삼각법의 장점은? | 3 목표물이 아닌 것들은 전혀 측정되지 않으며 조절된 빛을 사용하지 않을 경우에는 주위의 빛이 물체의 상을 올바르게 얻어내는 능력에 매우 영향을 준다. 이 방법의 장점은 구성 성분이 몇 개 없고 매우 싸며 작동 원리 또한 우리의 눈과 같아서 간단하다는 것이다.4 Fig. |
