Voxel-Based Texture Mapping and 3-D Scene-data Fusion with Radioactive Source.
ICIT(2020)
Abstract
Traditional nuclear imaging methods ignore the surrounding scene information and cannot determine the specific location of the radioactive source. If we can provide the information on scene-data fusion, the problem can be effectively solved. To achieve scene-data fusion, surface reconstruction and texture mapping are indispensable. But the related commonly used algorithms are all based on the point cloud, and the calculation process of the algorithm is very complicated and error-prone. Therefore, in this paper, based on the research background of nuclear imaging, we focus on voxel-based texture mapping and 3-D scene-data fusion. The method we proposed can display the radioactive source and the surrounding scene at the same time and realize the accurate positioning of the radioactive source in nuclear facilities. Experiment results show that the algorithm can accurately observe the intensity ratio and distribution of radioactive sources in nuclear facilities, at the same time can display texture information well, and has a good visualization effect.
