Optimal design of effective viewing field and structure layout of a two-CCD vision sensor

Based on the math-model of coordinate measurement of the two-CCDs vision sensor, which is established in this paper, the relationships among the coordinate measuring precision, the effective viewing field, the structural parameters of this sensor and the parameters of CCD itself are analyzed. In the meantime, the optimal structure layout is performed by means of computer simulation. And the simulation results show that the optimal layout of the two-CCDs vision sensor is symmetric structure.
