Abstract: During the renovation project of Beijing Workers Stadium, protection and restoration the original appearancerestoration of historical memory components were carried out. The 3D laser scanning technology was used to make a modelof the nine sculptures on the outside,including scanning environment processing, site selection, field scanning, point clouddata splicing. The practical details of protective removal of the window grilles on the exterior wall, 3D laser scanning and 3D printing of the original appearance were introduced. Practical experience shows that the digital model generated by 3Dlaser scanning technology has high accuracy, and 3D printing technology has strong practicability in making complexstructural components. Combination of the two technologies can be used to the protection and restoration of the historicalmemory construction.
