A novel multiaperture connection method for three-dimensional shape measurement is presented. The principle of multiaperture method is to obtain subapertures relative location and orientation by measuring the object from different subapertures, and afterwards connecting them together. Rrotation and transformation of subapertures are the key problems to realize multiaperture connection. In order to improve calculability and efficiency of the connection algorithm, a new connection method using quaternion is proposed. The mathematic model of multiaperture connection associated with our proposed method is discussed, and the experimental measurement on the basis of digital grating projection system is carried out to demonstrate the validity of this suggested method. Compared with the conventional connection method, this method offers with such advantages as computational simplicity, high efficiency and reasonable accuracy.
