Study on Three-Dimensional Displacement Measurement Method of EAST Cold Magnet Based on Computer Vision

摘要

The location of superconducting tokamak magnets decides the position and shape of plasma, it is significant of real-time acquiring the location of tokamak magnets to stably operate the tokamak. At present, magnet displacement measurement is taken in displacement sensor, but the factors affecting the measurement results have much because of tokamak structural features, this paper proposes an improved monocular laser triangle measuring method, it can effectively reduce the distractions, using the image processing software specially developed, we can quickly get magnet operating data, experimental results show that this method precision is high, this method can meet the requirements of the measure.
