A Target Localization Method for UAV Image Sequences Based on DEM Matching

Considering the deficiencies of low accuracy and poor real-time capability in traditional UAV target location, a method of high precision localization of UAV image sequences based on DEM matching is proposed. By calculating the DEM data of aviation reconnaissance area in advance, the image sequences from UAV television reconnaissance are corrected, then by matching the DEM data again, the target location for sequence images is realized. The experiments show that this method can meet the requirements of high accuracy and real-time performance in target localization for image sequences.
