1. A measuring device that measures a measurement object, the measuring device comprising:
a two-dimensional measuring unit that obtains two-dimensional image data by performing image pickup on the measurement object;
a three-dimensional measuring unit that obtains three-dimensional data by three-dimensionally measuring the measurement object;
an obtaining unit that detects a temporary edge of the measurement object using the three-dimensional data, sets an edge detection
range in a two-dimensional image using the detected temporary edge, and detects an edge of the measurement object in the edge
detection range using the two-dimensional image data to obtain shape information of the measurement object.
