Abstract
Optical coordinate measuring machines offer portability and the ability to capture vast quantities of data points quickly. But traceability of measurements in these systems is difficult since they are fraught with many challenges affecting the uncertainty of measurements, e.g. image noise, variable setups, point cloud based measurements. The VDI (Verein Deutscher Ingenieure) German standard is used for verification of these systems using non-complex artefacts that are easy to measure and have already been calibrated with other traceable measuring machines. ISO 10360–13 were only released in 2020. However, neither the VDI nor ISO standard cater for freeform surfaces. The Virtual CMM (Coordinate Measurement Machine) technique solves the problem of traceability of freeform surface measurements. This technique has only been applied to tactile CMMs and articulated arm optical CMMs, also known as discrete point systems, since they measure one point at a time. This research paper reports on the development and application of the Virtual CMM technology to a stereovision scanning optical coordinate measuring system.
