Abstract: A projection apparatus projects pattern light onto an object, the pattern light including pattern images corresponding to information that indicates coded projection coordinates in a projection coordinate system. Each of the pattern images includes two or more continuous areas. Widths of the two or more continuous areas are identical to one another, while lengths of the two or more continuous areas are different. An imaging apparatus captures images created on the object and generates captured images including imaging pixel values at imaging pixel coordinates in an imaging coordinate system. An image correction apparatus generates, based on the captured images, coordinate conversion information that associates the projection coordinates with the imaging pixel coordinates and corrects a projection image by using the coordinate conversion information.
