Abstract: A three-dimensional information reconstraction device includes a corresponding point detector that detects a plurality of corresponding point pairs to which a first feature point included in a first image captured by a first image capturing device and a second feature point included in a second image captured by a second image capturing device correspond, and a three-dimensional coordinate deriver that, based on the plurality of corresponding point pairs, reconstructs three-dimensional coordinates to which the first feature point is inverse-projected.

Abstract: The information presentation device has an image acquisition unit, a parameter deriving unit, an abnormality detection unit, and the presentation unit. The image acquisition unit acquires a first image which is captured by a first imaging device and a second image which is captured by a second imaging device. The parameter deriving unit derives parameters for deriving three-dimensional coordinates from the first image and the second image. The abnormality detection unit determines presence or absence of an abnormality in a relative positional relationship or a relative relationship of pose between the first imaging device and the second imaging device according to the derived parameters. In a case where an abnormality is determined, the presentation unit presents warning information including an instruction that there is an abnormality.

Abstract: A display device displays video for a virtual image. The display device includes a video generation unit generates image light representing the video, a concave mirror has a reflective surface on which the image light is reflected, and a support mechanism adjusts a position of the concave mirror. The concave mirror has, in each position on the reflective surface, a first radius of curvature in the first direction and a second radius of curvature in a second direction. The first radius of curvature and the second radius of curvature individually change and have different rates of change. The reflective surface has a shape following a partial region on an outer surface of an ellipsoid. The ellipsoid has a radius along the first direction that is greater than a radius along the second direction and a radius along a third direction orthogonal to the first direction and the second direction.
