Real-Time 3d Reconstruction Of Endoscopy And Microfiber Line Laser

Endoscopes, especially the structured lighting endoscopy, have been widely used in clinical applications for inspecting the interior of the patient. The purposse of this study is to provide an approach to reconstruct the 3D articular surface of the knee joint with an endoscopy (diameter empty set = 7 mm) and a line laser through a microfiber (empty set = 1 mm), facilitating computer-assisted diagnose (CAD) and improving operation quality for some open surgeries. Plane reconstruction of wood model is designed to examine the accuracy of this scanning system and experiment shows that the average accuracy is 1.186 mm. Finally, a 3D full view of the articular surface of the partial knee joint is presented to show the feasibility and simplicity of our proposed method.
