ARTICULATED ARM LOCALIZATION

Abstract:

Techniques for localizing a portable articulated arm coordinate measuring machine (AACMM) are described. An example localization method includes in response to an AACMM base being placed at a first position, capturing a first set of images of a positioning element in a predetermined area. The method further includes determining first 3D coordinates of the positioning element using the first set of images. 3D coordinates corresponding to a position of a first measurement probe in the predetermined area are computed using the first 3D coordinates. Further, the method includes, in response to the base being moved to a second position, determining second 3D coordinates of the positioning element from the second position using a second set of images. Further, the localization method includes determining a translation matrix to convert the second 3D coordinates to the first 3D coordinates.
