An optical assembly () for a three-dimensional measurement device is equipped with: an optical lens () that forms a pair of conjugate planes having an optically conjugate relationship; an optical device () that is disposed on one of the pair of conjugate planes; a temperature sensor () for detecting the temperature of the optical lens (); a heater () for heating the optical lens (); and a control part that controls the operation of the heater () on the basis of the result of the detection made by the temperature sensor () such that the optical lens () reaches a constant temperature.

Optical assembly for three-dimensional measurement device and three-dimensional measurement device equipped with same

A three-dimensional measurement system projects patterned light onto a target object, images the target object from different viewpoints to obtain a first image and a second image, obtains first depth information using the first image with a spatially encoded pattern technique, defines a search range for a corresponding point based on parallax between the first image and the second image predicted from the first depth information, and obtains second depth information by performing stereo matching for the defined search range using the first image and the second image. The second depth information has a higher spatial resolution than the first depth information. The patterned light has a combined pattern combining a spatially encoded pattern including a plurality of unit elements arranged regularly and a random pattern including a plurality of random pieces arranged randomly. Each of the plurality of unit elements is an area corresponding to a depth value.

Three-dimensional measurement system and three-dimensional measurement method

An illumination apparatus includes lenses, a first casing that has a radiation plane provided with annularly arranged windows for attaching the lenses, respectively, independently, and that has an opening at a position opposite to the radiation plane, and a first substrate associated with each of the lenses and accordingly disposed. The first substrate has at least one light emitting device mounted thereon. The first casing includes a holding portion associated with each of the windows. The holding portion each permits the lens to be attached to the first casing from a side thereof having the opening and also restrains the lens from moving through the first casing toward the radiation plane, and when the lens is attached to the first casing, the lens has an optical axis in a direction having a predetermined angle relative to a center axis of the first casing.

Illumination apparatus

An illumination apparatus includes an elongate chassis, a plurality of light emitting devices, a plurality of lenses, an elongate populated board, an elongate holding member, and a heat radiation member. The chassis includes a supporting portion supporting the opposite, longer-side ends of the populated board and a first engagement portion fitting and securing the holding member to the chassis. The holding member includes a plurality of second engagement portions fitting and securing each lens to the holding member and a resilient biasing portion resiliently biasing the longer-side ends of the populated board toward the supporting portion. The populated board is pinched and secured by the resilient biasing portion and the supporting portion and the heat radiation member is sandwiched and thus secured by the populated board and a bottom wall in contact with the populated board and the bottom wall.

Illumination apparatus and illumination system including a plurality of illumination apparatuses

An illumination device has a board, a plurality of light emitting elements that are mounted on the board, the plurality of light emitting elements being disposed such that a light irradiation direction of each light emitting element becomes substantially perpendicular to the board, and a plurality of lenses. Each of the plurality of lens is paired with one of the plurality of light emitting elements. A relative positional relationship between the light emitting element and the lens in each pair varies according to a position on the board in which the corresponding light emitting element is disposed.
