Research on Calibration Reading Technology of High-Precision Meter

摘要

The paper proposes a way to achieve camera positioning tasks by 2D visual servoing. By observing both the camera and the features of meter reading, the camera is able to be positioned with an accuracy in hand-eye calibration. The calibration reading method is used to recognize high-precision meter reading.The paper mainly includes three parts.Firstly,the geometrical model of parallax formation is constructed and the importing error is analyzed. Secondly, the calibration reading technology of high-precision meter is designed. Finally,the experimental platform calibration reading technology is designed. The experimental results show the method is applicable to automatic recognition of high-precision meter.
