In order to solve the problem, ccd is subdivided with paraboloid surface fit and newton interpolation. thus measuring accuracy of translation can attain sub - pixel level
為此必須對ccd進行細分，採用了牛頓插值法和二次曲面擬合方法，從而使平移量測量精度達到亞像素級。 -
In the experiment of this thesis, a high accurate measurement system based on linear array ccd is made up ; the illumination system is improved, and curve fit is adored to obtain the margin value. finally, the size of the obtained object is less than the pixel dimension according to lens magnification p
本文建立了基於線陣ccd的線徑高精度測量系統，在對照明系統改進的基礎上，採用曲線擬合求拐點的方法來提取信號的邊緣特徵，最後根據透鏡的放大倍率得到低於ccd像素尺寸直徑。
