摘要（英）：

A system for correcting plate detection error due to transverse temperature difference of cold-rolled strip comprises a strip-steel online temperature collecting module for receiving the temperature value signals Ti (i=1, 2, 3, 4, 5) of any five different positions in the width direction of strip steel and the coordinate signals Xi (i=1, 2, 3, 4, 5) thereof; a calculating module of fitted coefficient of strip-steel online temperature distribution curve for receiving Ti and Xi, using one step to four steps of Legendre orthogonal polynomial as the primary function to approximate the strip-steel transverse temperature distribution curve and then calculating the fitted coefficient a of each step; a plate characteristic point coordinate reading module in correspondence with the strip-steel basic aim curve for reading the characteristic point coordinates Y={y k}, (k=1, 2, Lambda, n); a correcting module for the plate measuring error due to transverse temperature difference of strip steel, which is used for receiving a and Y, correcting the plate measuring signal and outputting the transverse temperature difference compensation rate C={c k}, (k=1, 2, Lambda, n); and a corrected result implementation module.
