摘要: 为实现半球壳内外表面缺陷的高精度、非接触测量,在一种新型非正交系坐标测量机的基础上,提出了球壳内外表面缺陷的光学复合式测量方法。该方法将激光测量的点扫描与视觉测量的面扫描相结合,不仅可以测量表面缺陷的覆盖面积和分布,还可以测量缺陷的深度/高度。实际测量结果表明了该方法是可行的,具有较高的精度和效率。为实现半球壳内外表面缺陷的高精度、非接触测量,在一种新型非正交系坐标测量机的基础上,提出了球壳内外表面缺陷的光学复合式测量方法。该方法将激光测量的点扫描与视觉测量的面扫描相结合,不仅可以测量表面缺陷的覆盖面积和分布,还可以测量缺陷的深度/高度。实际测量结果表明了该方法是可行的,具有较高的精度和效率。

Abstract: To achieve high-precision and non-contact measurement of outer and inner surface defects on hemispherical shell, a optical composite measurement method was proposed on the basis of a new type of non-orthogonal coordinate measuring machine. It combined the laser probe’s point-scanning with the vision probe’s surface-scanning, and could measure not only the coverage and distribution of the surface defects, but also their depth/height. Actual measurement results show that the method is feasible, precise and efficient.

Key words: technology of instrument and meter, surface defect, non-contact measurement, hemispherical shell workpiece, defect identification
