Abstract: An object of the present invention is to provide a method for accurately measuring a three-dimensional shape of a measuring subject independent of the surface shape of the measuring subject, and another object thereof is to shorten the time from the measurements of the measuring subject until three-dimensional shape data is obtained so as to carry out efficient measuring operations. In a three-dimensional measuring system 1 that measures a three-dimensional shape of a measuring subject, two three-dimensional measuring devices 10, 20 are placed. The three-dimensional measuring device 10 measures a measuring subject placed in a measuring space 3 by allowing a laser slit light L1 in a longitudinal direction to scan in a lateral direction. Moreover, the three-dimensional measuring device 20 measures the measuring subject placed in a measuring space 3 by allowing the laser slit light L1 in a lateral direction to scan in a longitudinal direction.

Abstract: A spectral sensitivity correcting device in a photoelectric tristimulus colorimeter which comprises three light receiving systems for the measurement of tristimulus values. Signals indicative of respective outputs from two of the light receiving systems multiplied by predetermined correction coefficients are added to or subtracted from an output from the remaining light receiving system so that spectral sensitivity characteristics of the remaining light receiving system can approach predetermined spectral sensitivity characteristics.
