System and Method for Multiframe Surface Measurement of the Shape of Objects
First Claim
1. A method for the surface measurement of a material object, comprising:
- capturing at least one image of at least a portion of a surface of the object to be measured;
capturing at least one image of at least a portion of a surface of a reference object;
transforming captured images of the portions of the surface of the object to be measured into a coordinate system of the reference object; and
merging the captured images of the portions of the surface of the object to be measured in the coordinate system of the reference object.

Abstract
A system and method are provided for the multiframe surface measurement of the shape of material objects. The system and method include capturing a plurality of images of portions of the surface of the object being measured and merging the captured images together in a common reference system. The shape and/or texture of a complex-shaped object can be measured using a 3D scanner by capturing multiple images from different perspectives and subsequently merging the images in a common coordinate system to align the merged images together. Alignment is achieved by capturing images of both a portion of the surface of the object and also of a reference object having known characteristics (e.g., shape and/or texture). This allows the position and orientation of the object scanner to be determined in the coordinate system of the reference object.
