摘　　要：在银行业务中需进行印鉴真伪鉴别 ,然而 ,印鉴真伪鉴别系统的网络化实现有赖于相机的畸变标定 .鉴于银行业务要求 ,相机畸变的标定方法必须具有快速、可靠的特点 .为此 ,引入平行的L重Jacobi迭代法来实现相机畸变标定 ,这样可大大地提高标定速度 .Bank operation is in significant need of the checking system of seal impression(CSSI) that is beneficial to the protection of state and personal properties from encroachment and guarding against cheat. However, the network realization of CSSI depends on calibration of camera distortion. In view of the demands of bank operation, calibration algorithm of camera distortion must be quick and reliable. In order to eliminate camera distortion and get substantially better speedups, the calibration ideal of Chatterjee for camera distortion is adopted and a parallel L-tuple Jacobian iterative algorithm is introduced to implement the calibration of camera distortion, which has greatly increased the calibrating rate.
