Head-mounted display device, image processing device, control method of head-mounted display device, and non-transitory computer readable medium each of which estimate at least one of position and orientation of head-mounted display device

Abstract

A head-mounted display device includes a first camera provided on a front surface, a projector provided on the front surface and configured to project a pattern image onto an imaging range of the first camera, and a second camera provided on a side surface. The head-mounted display device acquires first information on a state of the head-mounted display device by detecting features of a real space from an image captured by the first camera, acquires second information on the state by detecting features of the real space from an image captured by the second camera, and generates an image of a virtual object, based on the first and second information, wherein the second information is acquired by detecting the features of the real space from an image in which the pattern image does not appear.
