In order to analyze the deformation and reconstruction process of hot-rolled strip deeply, the surface area of hot-rolled strip was inspected by the distributed method, and the error compensation reconstruction algorithm formed by curvature integral recursive method was determined. Then, the model simulation and deformation analysis of hot rolled strip were carried out to promote the significant improvement of reconstruction performance. According to the curvature data of the surface of hot-rolled strip, the strain distribution characteristics were judged, and the deformation data of hot-rolled strip were calculated. Furthermore, the multiple curves were formed and interpolated, so as to complete the deformation reconstruction process of the whole hot-rolled strip. The results show that with the increasing of load, the larger reconstruction variance is formed, and the maximum error decreases. Compared with the tangent angle recursive algorithm, the curvature integral recurision algorithm has smaller error and time consumption and obtains better reconstruction performance comparied with the tangential recurision method. Thus, the research result has a good effect on controlling the deformation degree of hot-rolled strips and has good practical value on improving the precision and stability control of strips in rolling process.
