title = "3D visualization of radioactive sources by combining depth maps generated from a stereo radiation detection device",
abstract = "This paper proposes a simple, yet efficient, idea to visualize the shape and complete spatial distribution of radioactive sources. We used our previously studied gamma radiation detection device to capture stereo images of radioactive sources (using gamma camera) and 2D vision scanning environment (using vision camera). To generate a complete 3D model of radioactive sources and to see their distribution in the scanning area, we captured stereo images at different locations by freely moving the detector. We used the well-known Semi-global Block Matching algorithm to create both radiation and vision disparity images at each location and generated corresponding 3D reconstruction results by calculating depth values. Color ICP-based registration is performed on each individual reconstruction result to generate integrated 3D models for spatial area and radioactive sources, separately. These two integrated models are merged with each other to visualize the complete shape of radioactive sources and its distribution in the scanning environment. A graphical example is presented to show that the proposed method is capable of generating neat 3D models in real-time.",
