本研究では,我々が開発した時間分解CMOSイメージセンサを用いた,Time-of-Flight(ToF)距離画像計測の硬性内視鏡への応用を検討した.内視鏡手術では閉鎖環境において生体の3次元形状計測を行うため,多重反射や生体組織の散乱によるマルチパスの計測距離への影響が問題となる.そこで本研究では,閉鎖空間内にある被写体と,様々な材料に対するマルチパスの計測距離への影響を実測した. |

In this study, we aim at applying time-of-flight(ToF) depth imaging to a rigid endoscope based on our time-resolved CMOS image sensor. In endoscopic surgery, three-dimensional shape measurement of a living body is performed in a closed environment, so that the measured distances have errors due to multipath effect such as multiple reflection and scattering of the living body. The influence on the distance of the multipath component due to the distance measurement of the object in the closed space and the subject of various substances was actually measured. As the fundamental study, the influence of the multipath by the closed space and materials was experimentally measured with our image sensor. |
