USING 3D VISION FOR AUTOMATED INDUSTRIAL INSPECTION |
| 摘要 |
A system and method for three dimensional (3D) vision inspection using a 3D vision system. The system and method comprising acquiring at least one 3D image of a 3D object using the 3D vision system, using the 3D vision system; extracting a 3D visible runtime mask of the 3D image; using the 3D vision system, comparing the 3D runtime visible mask to a 3D reference visible mask; and, using the 3D vision system, determining if a difference of pixels exists between the 3D runtime visible mask and the 3D reference visible mask. |

1. A method for three dimensional (3D) vision inspection using a 3D vision system, the method comprising:
acquiring at least one 3D image of a 3D object using the 3D vision system; using the 3D vision system, registering the at least one 3D image to a 3D reference image; using the 3D vision system, comparing the registered at least one 3D image to the 3D reference image; and using the 3D vision system, detecting a 3D difference between the registered at least one 3D image and the 3D reference image, wherein the 3D difference exceeds a 3D variance model. |
