Title: Evaluating a Ranging Protocol For 3D Imaging Systems
Published: September 19, 2007
Abstract: In 2006, the ASTM E57 committee was established to develop standards for 3D imaging systems. A 3D imaging system is a non-contact instrument that is used to measure the range and bearing to and/or the 3D coordinates of points on an object or within a region of interest. A draft protocol to evaluate the range error in these systems was proposed. Two rounds of tests were conducted in 2007 to evaluate the ranging protocol. The evaluation of the protocol revealed that it was impractical to test the proposed 60 combinations of factors due to the length of time required. However, sixteen combinations using planar targets can be completed in one day. Measuring the true distance from the 3D imaging system to the targets was done using a laser tracker during the first round of tests and a total station during the second round. The procedures for these measurements as well as the interaction between the above 4 main factors need further consideration.
