After analyzing the resolution distribution in the CCD intersecting target plane, resolution distribution research is performed by means of computer simulation. First, in order to calculate the resolution, formulas are derived corresponding respectively to the two CCD system and three CCD system. Then, the regularities of the resolution distribution in the target plane with a diameter of 3 meters are acquired correspondingly. As seen from the three dimensional figures of the resolution distribution, it can be concluded that the measurement system with three CCDs not only increases the capture efficiency of the object, but also improves the resolution distribution in the target plane.
