The 3-D coordinates corresponding to the image caught in 1/30 can be calculated in order to be used in reverse engineering. The system consists of two CCDs, two face lasers, and one line laser. The corresponding 3-D coordinates is obtained by calculating the geometric relationship between the projected lines and CCDs. Besides, the laser lines are grouped by searching laser lines in order to use the number of the face lasers as a constraint to solve the correspondence problem of the face lasers. Finally, a four degree matrix is used to solve the problem about the transferring relationship of 3-D coordinates and the image overlapping.
