- Image matching is an effective auxiliary location method for the precise guide weapon system. The image sensor of image matching system is used to real-time gather the object image around target or that throughout the flight way, which will be compared with the reference data of the upper computer in the missile, to process and locate the correct position of the target relative to the missile. The performance of the image matching system is vitally interrelated to the geographic and conditions (Ground image characteristics) of the operation region. So the basic operation condition of the image matching system and matching region selection in the special geographic conditions is regarded as the main contents to study. Taken the developing demands of an important national defense weapon system as the background, we carry out a series of theory analysis and simulation study base on the actual data, in order to improve the matching accuracy of the down-look image matching system and determine the main factors influencing the operation performance of the image matching system in further. And we build a set of functional relationship relative to the performance and specifications of the image matching system, image statistic parameters and operation conditions. By analyzing and verifying these functions relationship, finally we point out the parameters influencing the image matching system under different environmental conditions, and point out principle thought and method of selecting image matching area according to these parameters. These study results have been used and proved in the product development. And it provides the basis for us to determine the selection regulations of matching area of down-look system, laying a foundation for improving the operation performance of the image matching system in different environmental conditions.
