Abstract
An imaging system in which a two-dimensional photographing device and a unit for three-dimensional measurement are removably attached to each other is provided. The system can be easily used for taking a two-dimensional image and for measuring three-dimensional data. The imaging system is used for conducting three-dimensional measurement of an object and taking a two-dimensional image of the object. The system includes a photographing device and a three-dimensional measurement auxiliary unit formed in a housing provided independently of the photographing device to be removably attached to the photographing device. The photographing device can take a two-dimensional image without the unit and can function as a light receiving portion in three-dimensional measurement to conduct three-dimensional measurement in cooperation with the attached three-dimensional measurement auxiliary unit.
