PROBLEM TO BE SOLVED: To provide a three-dimensional measuring device in which a bright line on an image can be made corresponding to a light cutting plane according to any other method than bright line identification depending on colors, and a three-dimensional measuring method.SOLUTION: In a three-dimensional measuring device 1, a workpiece 2 is irradiated with slit light from a flood lamp 7, and the workpiece irradiated with the slit light is imaged by a stereo camera 5. A controller 10 of the three-dimensional measuring device 1 temporarily makes a bright line 4j captured in a first image, among captured stereo images, corresponding to a light cutting plane 6Pj and projects the bright line on the light cutting plane 6Pj. The bright line projected on the light cutting plane 6Pj is then projected on a second image. The controller 10 computes a degree of matching between a bright line 4jX projected on the second image and a bright line on the second image and determines whether the corresponding relation is right. |
