Abstract
In flatness measuring by correlative stitching technique, a bigger scale's measurement can be realized by the system witha smaller measurement caliber. At the same time, high measurement precision, high spatial resolution and low price can be maintained. In this technique, mode building and solving are especially important. Aiming at some problems in common mode building and solving, the paper presents a new solving method. The iterative least-squares technique is applied in the method and it considers not only the information in height, but also the influence of the parameters in other directions which are usually predigested in common modes. By this solving method, the demand for rail of systems is decreased. Some simitations are done to testify the presented method.
