The parameters of the camera and the projector are simultaneously estimated by using non-linear least-square estimation model, whose outputs contain the estimated parameters and their accuracys.
A compound digital filtering method and a line fitting method based on the least squares are presented, which are used in the measurement system of interface parameters of artillery.
According to the request of grid concurrent operation of nonlinear programming, the parallel repetitive process is proposed to enhance its parallel based on analyzing the repetitive process of NLS.
