Image mosaic is a technology which uses space matching alignment to the mutual

between the overlapping portions of the image sequence to get the complete image which

includes more information. It includes image matching and image fusion. On the basis of

above theory, line structure light as specific artificial point was placed in the surface of the

detected object, so that we can narrow the search scope of feature points to be extracted,also

feature points were easy to match.Thus shortened the corresponding calculation and improved

the speed and accuracy of the match,had robustness in a way. The dissertation introduce a

coding scheme which base on the theory of channel coding in the information theory. This

coding scheme can correct the error automatically when appeared an error.
