亚像素配准误差 sub-pixel registration error
To reduce the effect of the error,trapezoidal target is used,which includes both rough division and subdivision. Then,the formula of the error MTF,which results from the initial registration error,is deduced under the Nyquist frequency.
为了减小配准误差对测量的影响,提出了采用粗分与细分相结合的梯形靶标,并推导出在奈奎斯特频率下动态测量调制传函时,由采样初始时刻配准误差所引起的配准误差调制传递函数MTF计算公式,并按此公式分别得到了粗分精度和靶标斜率对测量相机系统MTF精度的影响。
