PROBLEM TO BE SOLVED: To provide a three-dimensional measurement device capable of accurately performing the three-dimensional measurement of a traveling object with simple configurations by using an inexpensive camera.SOLUTION: The three-dimensional measurement device includes: a plurality of cameras 2 and 3 including imaging elements whose exposure timings are different for each line; light projection means 4 for projecting the rays of light toward the traveling object 8; detection means 5 for detecting that the traveling object 8 has reached a measurement position which is measured by the plurality of cameras 2 and 3; control means 6 for controlling the exposure of the plurality of cameras 2 and 3 such that all the lines of the plurality of cameras 2 and 3 are put in an exposure state, and for controlling the light projection means 4 to project the rays of light in a period when all the lines of the plurality of cameras 2 and 3 are put in the exposure state: and three-dimensional distance calculation means 7 for calculating the three-dimensional distance of the traveling object 8 on the basis of images photographed by the plurality of cameras 2 and 3. |
