<p>PROBLEM TO BE SOLVED: To provide a device for detecting flatness capable of detecting flatness at a high speed, and further to provide a method for detecting flatness.SOLUTION: A device 1 for detecting flatness comprises: point group data acquiring means 21 for acquiring point group data from a three-dimensional measuring device 2 which performs shape measurement of three-dimensional positions (x, y and z) of a plurality of places of an object (work-piece) surface and generates the point group data constituted of three-dimensional positions of individual ones of the plurality of places; coordinate converting means 22 for converting an x coordinate value and a y coordinate value into integers out of the three-dimensional positions (x, y and z) in the point group data and calculating a z coordinate representative value with respect to each of the x and y coordinate values; z integrated value calculating means (integration height calculating means 26) for calculating a z integrated value obtained by integrating the z coordinate representative value with respect to a plurality of sub-regions obtained by dividing an x-y plane region; and comparing means 28 for comparing the z integrated value of the sub-region divided and the z integrated value of the sub-region adjacent to the sub-region divided.</p> |
