Robot vision is a kind of science and technology concerned with multiple disciplines to enable a robot
to see. Its specified aspects that are attracting the attention of the researchers in robot community include
architecture and calibration of visual systems, visual measurement methods and visual control approaches. The
aspects above are investigated and analyzed according to current works, respectively. Furthermore, their
tendencies are also predicted. The visual measurement principles from parallax to knowledge and the visual
control strategies from traditional control methods to humanoid approaches are regarded to have promising
future.
Keywords: Architecture, calibration, visual measurement, visual control, robot vision.
