Abstract

This paper describes continuing work with three-dimensional (3-D) rotating line-scan vision systems in robotics and measurement. Mathematical algorithms have been developed for use with the line-scan arrangement allowing the extraction of three-dimensional co-ordinate information from an observed object workspace. To determine the measurement capability of the stereoscopic system, comparison is made between the system output data (calculated from image space values) and a calibrated volume in object space containing a distribution of target points. This paper describes the mathematical model and results pertaining to the current research demonstrate the use of the rotating line-scan scenario to the solution of specific applications where conventional sensor modalities may not be appropriate.
