In the course of measurement of workpiece face runout, variance method of the most species based on separability and image edges distilling based on morphology and marr filtering based on edges segmentation are used to enhance effectively accuracy of image segmentation and edges distilling. accuracy of measurement of face runout is enhanced effectually by use of least square method of compressing rectangle fitting edge of image and transforming of dft
該系統在工件端面跳動測量過程中，採用了基於可分性的最大類間方差法和形態學邊緣提取以及基於邊界分割的marr演算法，使圖像分割和邊緣提取的準確性得到了很大的提高；用壓縮矩形的最小二乘法擬合工件端面圖像的邊緣以及用dft變換對工件端面的跳動量進行測量，使端面跳動測量的準確性得到了很大的提高。On the basis of current investigation of both the domestic and foreign and current level of development, and contraposing difficulties and keys of autofocusing and measurement, this paper brings forward system of autofocus and measurement based on techniques of image processing of ccd. this system possesses merits of fast speed, high precision, small bulk and large dynamic range. it is able to carry out needs of fast, accurate, large range autofocusing and requests of noncontact and online measurement of workpiece face runout
本論文根據目前國內外現狀和發展水平，針對自動聚焦和端面跳動測量的關鍵點和難點，在普通光學儀器的基礎上提出了一種基於ccd圖像處理技術的圖像式自動聚焦及其測量系統，該系統具有速度快、精度高、動態范圍大、體積小等優點，實現了快速、精確、大范圍的自動聚焦和對工件端面跳動進行非接觸、在線測量的要求。
