Abstract: The invention provides a projector apparatus with a distance image acquisition device and a projection mapping method that can project an image focused on the entire projection object even in a case in which there is a difference in distance to the projection object and the projection object moves. Two projector apparatuses with a TOF camera, that is, a first projector apparatus with a TOF camera including a first projector apparatus for a far distance and a first TOF camera that acquires a distance image of a far projection object and a second projector apparatus with a TOF camera including a second projector apparatus for a near distance and a second TOF camera that acquires a distance image of a near projection object can project a projection image for a far distance and a projection image for a near distance which are focused on the entire projection object even in a case in which there is a difference in distance to the projection object and the projection object moves. In addition, a first light source and a second light source of the projector apparatuses are pulse-driven to function as light sources of the first and second TOF cameras.

Abstract: Three-dimensional measurement apparatus comprises first and second imaging units with baseline length, feature point detector for detecting feature points in image, corresponding point detector for detecting corresponding points corresponding to the feature points, rotation matrix calculator, translation matrix calculator, distance calculator, and data calculator. Based on the feature points and the corresponding points, the rotation matrix calculator calculates a rotation matrix representing direction and amount of rotation of a second image capture position relative to a first image capture position and the translation matrix calculator calculates a translation matrix representing a translation direction of the second image capture position relative to the first image capture position. Based on the rotation matrix, the translation matrix, and the baseline length, the distance calculator calculates a translation distance to the second image capture position relative to the first image capture position. The data calculator calculates three-dimensional data based on the translation distance.

Abstract: A system control portion generates corrected image data by performing reduction processing of reducing input image data input into a display portion at a first reduction rate and image shifting processing of shifting positions of R image data and B image data of a specific color component included in reduced image data obtained by the reduction processing. The system control portion projects a corrected image based on the corrected image data to a screen by inputting the corrected image data into the display portion.
