Abstract: A three-dimensional shape measuring method includes: a first step to: project first and second projection images on a target object, wherein the first projection images include row-direction stripe patterns different from each other, and the second projection images include column-direction stripe patterns different from each other, and obtain first and second captured images of the target object, wherein the first captured images are captured while the first projection images are projected, and the second captured images are captured while the second projection images are projected; a second step to identify a corresponding projection pixel of the first and second projection images, wherein the corresponding projection pixel corresponds to each of captured pixels of the first and second captured images; and a third step to identify a 3D shape of the target object based on a result of the second step.

Abstract: A video display device includes: a display element displaying images by modulating light from an illumination optical system; and an eyepiece optical system guiding image light from the display element into an optical pupil. The illumination optical system includes: a light source including light emission points arranged substantially linearly; a diffuser plate diffusing illumination light from the light source in a first direction, in which the light emission points are arranged, but not in a second direction perpendicular to the first direction; and an optical element bending the illumination light such that the optical pupil and the light source are substantially conjugate. The optical element includes an illumination mirror, a reflection surface thereof having a non-zero curvature in all sections including a normal line at the optical-axis intersection. Here, the section perpendicular to the first direction has a different curvature from the section perpendicular to the second direction.

Abstract: An object is captured in an image taken by the camera. An external shape of the object is recognized from the image. An internal shape of the object is recognized from the image. Parts information of the object is then determined, using a result of the recognition of the external shape and/or a result of recognition of the internal shape.

Abstract: An intraoral measurement device includes: a device main body that holds a base end side of a prism by a housing, the housing accommodating an illumination member and an imaging member, a cover member that is attached to the device main body in a state of covering, with a space part interposed in between, a distal end side of the prism arranged to face a measurement target, in which a part arranged to face the measurement target is formed by a light transmission window; and a heat transfer member that extends from the device main body along a non-optical surface of the prism, and transfers heat of the device main body to the light transmission window through abutment of a protruding end provided to protrude from the prism against the light transmission window of the cover member.
