Abstract
A three-dimensional shape input device for entering a three-dimensional shape of an object by a light projection method is provided, which includes a light projecting portion for projecting detection light onto an object, and an imaging portion for receiving reflected light from the object. The device includes a storage portion for storing a parameter that is used for computing the three-dimensional shape, a computing portion for computing the three-dimensional shape of the object by using image data delivered from the imaging portion and the parameter, and a dividing portion for dividing an imaging surface of an image sensor into plural areas. The storage portion stores parameters each of which is to be applied to each of the areas. The computing portion performs computation for each of the areas by using a parameter to be applied to each of the areas.
