Other Abstract

The invention relates to a different-source test image calibration method of an image matching system, comprising the following steps: establishing a similar feature index candidate set of visible-light image and infrared image sequences; using a grey correlation analysis method to measure the similarity between the features in a different-source image candidate set, performing correlation degree sorting on the similar feature index candidate set on the basis, and selecting similar feature vectors; selecting different parameters according to the threshold parameter of an edge feature extraction algorithm based on a Canny operator, calculating and dividing feature value combinations, and forming a calibration test pilot scheme; and making a statistic analysis of the matching rate of a photoelectric imaging matching system to visible-light images and infrared images, performing grading based on a matching rate result output by an infrared image, and calibrating the feature value range of a corresponding visible-light image. Through the method, the matching system can be tested and evaluated through use of a calibrated visible-light image when working in an unknown environment, and therefore, the image matching system can complete the task smoothly.
