Abstract
A three-dimensional reconstruction method based on half-peak probability density distribution, including: slicing three-dimensional point cloud along Z-axis direction to obtain N spatial layers; extracting the scatter information in i-th spatial layer and projecting information to Zplane; constructing membership function of each grid and scatter in the Zplane and drawing a three-dimensional probability density plot; making a plane parallel to XOY plane through half-peak wof three-dimensional probability density plot, parallel intersecting a three-dimensional probability density plot to obtain a contour L; superimposing radioactive source reconstruction contours corresponding to N spatial layers sequentially to obtain a three-dimensional reconstruction model of a radioactive source. The method can be applied to the nuclear electrical field, to achieve the rapid reconstruction of radioactive sources after nuclear accidents and accurate contour reconstruction after decommissioning of radioactive sources.
