3D map reconstruction with sensor kinect: Searching for solution applicable to small mobile robots

Various dentistry fields such as teeth treatment, dental restoration, and denture production require the application of three-dimensional intraoral scanners to create digital impressions. This study presents a method to reconstruct a three-dimensional teeth crown by utilizing a prototype intraoral custom design with publicly available software. The system consists of custom containing an endoscope camera and two light sources (white LED and blue laser), a personal control computer, and photogrammetric open source software packages (VisualSFM, CMVS/PMVS, and MeshLab). Photogrammetry methods were used to acquire the three-dimensional teeth model with high precision. Multi images have been captured of the interesting teeth using the custom system from different angles. The capturing process was done in two phases using one illumination source each time. The captured images are loading to Photogrammetry software to generate the three-dimensional dense point cloud. A comparison has been made of the resulted dense point cloud at each phase. Finally, the dense point cloud is loading to MeshLab software to generate the three-dimensional mesh that can be utilized in CAD/CAM software. The results have shown the superiority of using blue illumination with the photogrammetry software that shows good accuracy of teeth crown details and measurements that are related to the reconstruction algorithm which yields in more number of 3D points of the object to generate good three-dimensional meshes of the teeth crown. This study helps to offer low cost, simple design, and a user-friendly system to generate a three-dimensional teeth crown.
