Abstract

According to the special measurement requirement of the magnetic field distribution of radar electromagnetic focusing system, an automatic measurement instrument based on vision localization has been developed. The principles of vision localization and model construction of measurement instrument are described. Two key points of nonlinear calibration and coordinate transformation are analyzed in detail, and some experiments based on this method are given. The application of the vision localization shows that it can calculate all the real coordinates of holes accurately. As a result, the three-dimensional rectangular robot can fulfil the measurement task perfectly
