The Avalokiteshvara Bodhisattva statue on the south wall outside Wanfodong Cave in Longmen Grottoes is praised as “the most beautiful Avalokiteshvara Bodhisattva in Longmen” on the basis of its exquisite carving skill and graceful shape. However, affected by human and natural factors, the statue face has become incomplete and the paint has almost disappeared. Therefore, making virtual restoration to reshow its complete appearance is important for the relevant archaeological research and exhibition. Based on a historical picture, we used a method combining 3D digitalization and sculpture repair to realize the virtual restoration of the shape and stony texture. A virtually restored physical model was made by high-precision SLA 3D printing. The remaining paint components were determined using X-ray fluorescence spectrometry and Raman spectrometry. On this basis and according to its remaining paint distribution and the color style of statues of the same period in Longmen Grottoes, the virtual color restoration of the Avalokiteshvara Bodhisattva statue was finished. In this scientific research practice, an entire technological process for the virtual shape and color restoration of incomplete cultural relics was designed and its feasibility was verified. The coloring of the physical model and utilization in exhibitions were also realized.
