| Popis: | Current methods for the imaging of radioactive sources ignore the surrounding scene information. Reconstruction results do not have real scale meaning, creating difficulties for further disposal and management of nuclear waste. In addition, the traditional reconstruction method requires fixed hardware to directly measure the reconstruction parameters. In recent years, the combination of computer vision and traditional radiation imaging has been greatly performed. The binocular camera is a small, light-insusceptible visual instrument, suitable for integration with other instruments. In this article, we present a method based on binocular vision technology to radioactive source image reconstruction. The binocular camera provides the assisting information about the surrounding scene and replaces the fixed hardware to indirectly achieve the measurement target of reconstruction parameters, which includes an azimuth angle and a distance. In addition, we designed a simple algorithm based on the Hough transform and the regular shape of the waste drum to improve the spatial resolution for good visualization. The experimental rendering results with different transparency degrees provide a good sense of spatial scale. |
