Six Degrees-of-Freedom Measurements for the Checking of Parallel Structures Configuration

摘要

The content of the paper is focused on the six degrees-of-freedom (DOF) measurements for the checking of parallel structures mutual configuration. Described measurement system is derived from the pyramid modular sensory system for the sampling of six-component information about three axial shiftings and three angular displacements The subject of this device is the sampling and information processing used in the conversion of four 2-D CCD arrays images into three axial and three angular displacement values. The modular design presented here enables the six DOF measurement by-means of three alternatively used universal modules for the macro measurement.
