Abstract:
An apparatus for measuring geometry elements, comprising:a two or three-dimensional coordinate measuring machine for measuring one or more sample points on a work required to calculate a geometry element which defines the work to be measured and outputting measured data containing two or three-dimensional coordinates; a sampling and sample processing section for receiving said measured data of said sample points measured by said two or three-dimensional coordinate measuring machine and counting the number of said sample points received; and an element discriminating section for discriminating a distribution of said sample points which is defined by any one of zero through third degrees, on the basis of a thickness, width and height of the minimum rectangular parallelepiped which internally contains all sample points received by said sampling and sample processing section and for discriminating said geometry element which defines the work to be measured on the basis of the number of said sample points received by said sampling and sample processing section and said distribution of said sample points.
