【Abstract】 In the field of engineering there is often need to gather a lot of serial digital images, which should be mosaiced speedily and precisely, and also displayed in real time. Aimed at the need, a speediness mosaic technique and its mathematical model based on isometry serial images are proposed in this article. Using this technique, the initial position of mosaic point is calculated firstly by Fixed Mask Correlation Algorithm, and the other position of mosaic point can be gained by a precise grating localizer, so the serial images are mosaiced one-off by the mathematical model. Furthermore, the experiment of laser interferometer is used to verify the mathematical model and the results data show that the technique and model can greatly improve the efficiency of serial image mosaic with enough accuracy.更多还原
