The 3D vision offline quality and metrology cell is the ABB standard cell for off-line quality inspection. It offers a faster, more dynamic technology than traditional CMM (Coordinated Measuring Machine) based methods. The measurement is performed without contact, using only structured light for the object geometry, by projecting light patterns onto the measured part, with the resulting data being used to create a digitalised high-density 3D point cloud representation of that part. The procedure for calibrating the working volume consists in taking images of the space of interest from different positions and with different camera angles. Each shot locates an independent number of simple targets, coded targets and the scaling bar. Once the whole capture process has been completed, the data are processed and the user is provided with a file with the XYZ position of all the measured simple targets. These XYZ references will be used to combine all the digitalization made while the parts are measured.
