Calibration for vision system
27 Jul 21
A vision system capable of performing run-time 3D calibration includes a mount configured to hold an object, the mount including a 3D calibration structure; a camera; a motion stage coupled with the mount or the camera; and a computing device configured to perform operations including: acquiring images from the camera when the mount is in respective predetermined orientations relative to the camera, each of the acquired images including a representation of at least a portion of the object and at least a portion of the 3D calibration structure that are concurrently in a field of view of the camera; performing at least an adjustment of a 3D calibration for each of the acquired images based on information relating to the 3D calibration structure as imaged in the acquired images; and determining 3D positions, dimensions or both of one or more features of the object.
