Abstract: 3-D errors are analyzed when metering section dimensions of steel sections with optical section method, and the model of 3-D errors is proposed with perturbation method and calculations are completed. On the basis of the results and analysis, the requirements of design scheme for measuring apparatus are given.

Key words: Hot rolling steel shape, On-line inspection, Perturbation
