Title:
SHAPE MEASURING AND PROCESSING METHOD
Document Type and Number:
Japanese Patent JPH04276513
Kind Code:
A
Abstract:
PURPOSE:To improve the freedom in selecting a measuring point and a reference point by converting point-group data into curved-surface data, computing the point groups required for obtaining the difference between both curved surfaces for shape measurement and a shape reference, and operating the difference between the point groups. CONSTITUTION:Even if both or one of the measured shape data obtained by measuring the size of the shape of a work to be measured and reference shape data which are set for the work to be measured are the point group data, the point group data are converted into the curved-surface data. Therefore, both the measured shape data and th shape reference data become the shape data of the curved surfaces which are continued in three dimensions. Therefore, any position which is deviated from the positions of the point-group data of both the measured shape data and the reference shape data is selected, and the difference can be operated and displayed. Thus, the freedom in selecting the measuring point and the reference point is improved, and the quick, accurate evaluation can be performed.
