Outline of Final Research Achievements

This study aims to develop a 3D reconstruction system using arthroscopy which has been focused recently. The conventional arthroscopy can provide information of internal human body by inserting a camera to a minimum space. However, it hardly provides depth information. Therefore, this study tried to reduce the size of the system which can be used in clinical situation, and to reconstruct 3D shape of a target. The system consists of a camera and a line laser. The total diameter was about 10.0 mm. The depth length to a target was set to be 10 mm, 15 mm, and 20 mm, respectively. The average of the total was about 0.50 mm. The standard deviations of each groups were 0.503 mm, 0.899 mm, and 1.480 mm, respectively. This indicates that the purpose of this study was realized. A future work is to apply the proposed system to a target under water which can be assumed in clinical situation.
