Paper Abstract

A geometric model-driven strategy for measuring an object's dimensions in three dimensions using image processing is discussed. A laser range scanner is used to collected 3D data points from the scene. By constructing a geometric model from a CAD data base or from a sample object during the setup phase, an inspection index is established according to the user's inspection requirements. Useful information about the object is recorded in the inspection index to guide image processing during the later inspection phase when many similar objects are measured. The inspection index is generated off-line by analyzing the object's geometric features, their relationships with dimensions and other attributes. Examples of the inspection index as well as experimental results of rapid, on-line measuring is presented.
