Abstract: A three-dimensional measuring device includes an extraction unit that extracts an image data set with a brightness value of each of pixels in image data within an effective range from among a plurality of image data sets at each of coordinate positions of an object to be measured, and a three-dimensional measurement unit that performs three-dimensional measurement relating to each of the coordinate positions of the object to be measured based on the extracted image data set. The extraction unit extracts the image data set imaged under a pattern light with the highest irradiation brightness among a plurality of types of pattern lights when there is a plurality of sets of the image data sets with the brightness value of each of the pixels in the image data within the effective range from among the plurality of the image data sets.
