Abstract: The establishment of image fusion process and the optimization of image fusion method are the keys for next image fusion treatment，and which also directly determine the fusion effect and its application.A modeling method on multisensor image fusion process is analyzed and researched，and moreover a closed image fusion process taking image data as input，fusion model and fusion rule as core，fused images as output and fusion appraisal system based on multifactor integrative criterion as terminal is presented.Finally，by comparing with the results according to a certain appraisal method，a last fusion algorithm is recommended.The algorithm is more simple，practical，accordant to subjective and objective appraisal methods，and adaptive with image data and fusion purpose.
