Abstract / Hauptanspruch
A three-dimensional measurement device (1) includes a light source unit (31) that emits distance measurement light (35), a projection light optical system (33) that causes the distance measurement light to be emitted along a distance measurement light axis (36), a light receiving optical unit (41) that receives the reflected distance measurement light (61), a light receiving and splitting unit (42, 42A, 42B, 42C, 42D, 42E) that splits the reflected distance measurement light that has transmitted through the light receiving optical unit into first reflected split light (62) and second reflected split light (63), attenuates intensity of the second reflected split light to be lower than intensity of the first reflected split light, and converts the first reflected split light and the second reflected split light into electrical signals, and angle detection units (14, 18) that detect a light emitting direction of the distance measurement light.
