A simple and rapid approach is proposed to determine robot location by using a known-height regular prism. In the approach, no intrinsic camera parameters are known in advance, so alignment error can be avoided. The dimension parameters of the regular prism can also be derived. To shorten the computer calculation time, only 3-D vector algebra is used in the robot location scheme, the time of location determination is 0.2 s, and the measurement error is less than 3% on average.
