Analysis and Evaluation Method of Scene Matching Based on Combination Tracking

In scene-matching flight trials, the drastic scale changes in the image sequence and the geometric deformationcaused by the influence of various external factors increase the difficulty to evaluate the whole process of scene matching au.tomatically.A whole-process evaluation method of scene matching based on combination tracking is proposed. Firstly, a se.quence image keyframe method based on the principle of sequence images keyframe selection is proposed, and the methodis compared with various target tracking algorithms. Then, according to the comparision analysis results, a scene matchingwhole-process evaluation method based on the combination tracking algorithm of sequence image matching and TLD is pro.posed. Finally, the combined tracking method is applied to three sets of simulation experiments. The results of evaluation ex.periments show that the method enables reliable and rapid whole-process evaluation of sequence images is highly adaptableto image rotation, scale change, image noise, image blurring, and gives quantitative evaluation conclusion in the form of two-dimensional graphs.
