３次元情報検出装置

Japanese Patent JP6761488

B2

Provided is a three-dimensional information detection device having a configuration in which detection accuracy of three-dimensional information of a measurement target object is not lowered even in a case where an optical system that includes a projection unit, a first imaging unit and a second imaging unit is covered with a light transmissive cover so that the optical system is not exposed to the outside. The three-dimensional information detection device includes the projection unit that projects an image pattern onto a measurement target object, the first imaging unit and the second imaging unit that respectively image the image pattern, a transmissive cover that covers the optical system that includes the projection unit, the first imaging unit, and the second imaging unit, and a calculation unit that calculates three-dimensional information of the measurement target object on the basis of the image pattern that is imaged using the first imaging unit and the second imaging unit. At least a part of a mounting surface of the optical system is formed by a light absorbing member, and the first imaging unit and the second imaging unit are disposed out of a region to which reflected light that is regularly reflected from the cover in projection light of the image pattern is directly incident.
