A three-dimensional shape is measured by a simple system structure. A three-dimensional shape measuring instrument comprises a device ( 1 - 1 ) in which a light-emitting diode ( 1 - 1 b) is installed as a marker in a line laser light source ( 1 - 1 a), an imaging device ( 1 - 2 ), and a computer ( 1 - 3 ). For measurement, a line laser beam from the device ( 1 - 1 ) is applied to an object ( 1 - 4 ) to be measured, the imaging device ( 1 - 2 ) images the applied line laser beam ( 1 - 5 ) and the light-emitting diode, and a three-dimensional shape is obtained from the image data by triangulation by means of the computer ( 1 - 3 ). |
