Rapport
| Résumé : | This report presents a one year lasting study. The purpose is to develop a three dimensional endoscope able to meet the major requirement of his application : low space occupied, high depth resolution and visual comfort. The first part is dedicated to the state of the art, where three methods are specically detailed : sterevision, time of flight camera and structured light analysis. The structured light analysis technique has been selected for the development. Before proceeding to the design of the device itself, a 3DS Max model has been made as it offers the possibility to optimise the settings such as the pattern used or the geometry of the original device. This model has been providing good pictures required to develop an interface dedicated to optimise the settings involved in such a device, such as the projected pattern and the geometry of the device. First results have shown encouraging results, it is able to compute a 3D Mesh of the stomach based on the picture taken in a 3DSMax model. In the second part, a device is proposed which does not require extra space with respect to the design of common endoscopes. The device proposed is based on a diffractive element, a laser and an optical ber bundle and meets the requirements of the application. This device will be developped in further development. |
