Three Dimensional Image Reconstruction Method Based on Two Dimensional Radar Image and Optical Image

Since the building room consists mainly of three brick walls and one glass wall, Unmanned Aerial Vehicle (UAV) equipped with optical sensor and radar sensor detects targets only from a specific view during monitoring the building fire explosion site. The unknown height information of combustible objects in the two dimensional (2-D) radar image and the unknown range information of combustible objects in the 2-D optical image makes it difficult to get comprehensive information. By fusion of the range and azimuth information extracted by the 2-D radar image and the height and azimuth information extracted by the 2-D optical image, in this paper, a new algorithm is proposed to reconstruct a three dimensional (3-D) image with the correct range, azimuth and height information of combustible objects. The simulation results validate the correctness and feasibility of the algorithm.
