It is possible to measure a 3-dimensional shape by using a projector and an imaging device without requiring calibration in advance. A pattern light (1-5) is applied from a projector (1-1) to an object (1-4) and this is imaged by an imaging device (1-3) to capture an image as an input. An in camera parameter, an in-projector parameter, a parameter of positional relationship between the camera and the projector are estimated. By using the estimation results, a 3-dimensional shape of the object is measured. When a laser pointer (1-2) is attached to the projector and a laser is applied to the object for capturing an image as an input, scaling of the object shape can also be estimated. Moreover, when measuring a plurality of objects or measuring the same objects a plurality of times, the accuracy of the 3-dimensional shape respectively obtained can be increased by simultaneously processing the inputs. Moreover, when one of projector and the camera is fixed and the other is moved while measuring the same object a plurality of times, the accuracy of the 3-dimensinnal shape obtained as a result can be increased by performing bundle adjustment. |
