Uncertainty of line camera image based measurements

Line Camera has been emerging as an effective approach to contactless measurement systems. Line cameras are preferred to area scan cameras in specific applications where the object to be scanned has one dimension much greater than the other two (e.g. train). In this paper, a line camera analytic model and its calibration procedure, are described. A significant part of the paper is dedicated to measurement uncertainty. Simulation and experimental results are reported to describe how uncertainty due to the calibration procedure influences the final uncertainty of dimensional measurements.
