<P>PROBLEM TO BE SOLVED: To provide a reference scale which is excellent in a handling property and workability regarding generation of a teacher line and for generating the teacher line with higher accuracy as for generating the teacher line in measurement of a feature on an image. <P>SOLUTION: A reference scale 31 is constituted by being provided with: an X direction scale 32; a Y direction scale 33; and a Z direction scale 34 which are used for generating a teacher line whose absolute length is known on an image to be obtained by being photographed with a camera for measurement based on a dissipation point in measurement of a feature on the image for performing measurement of the feature fetched in the image based on the dissipation point on the image, each of which is combined so as to extend for the respective coordinate axes, X, Y, Z of three-dimensional coordinates in a subject space of the image for measurement of the feature, and each of which is provided with graduation showing the absolute length to be known. <P>COPYRIGHT: (C)2013,JPO&INPIT |
