The operational error of a virtual reality (VR) assisted vision-based microassembly system is measured and calibrated during the system development stage. The vision-based microassembly system was designed and its opto-mechanical model was established in a virtual environment. By measuring the errors between the representative points in the images of virtual cameras and charge-coupled device (CCD) visual systems, the errors in the virtual environment were compensated by correcting the projection matrix parameters, the view matrix parameters, the initial components position, and the deviation angle for the working stage motion. The effectiveness of the proposed VR-assisted fine calibration method was tested by performing VR calibration on the virtual system.
