The murals in Yongle Palace possess extremely high artistic and historical value. Its protection work is facing huge challenges. Traditional repair methods have limitations. Digital technology offers a new direction for the protection of murals. This article aims to construct a digital restoration technology system. This system is specifically applied to the protection of the murals in Yongle Palace. The study first reviews the existing technologies. Digital acquisition technology can obtain high-precision information. Intelligent algorithms can automatically identify diseases in murals. Virtual repair technology can digitally restore the damaged area. This paper proposes a three-layer technical framework. The first layer is the precise collection of digital information. Combining high-resolution scanning with multispectral imaging. The second layer is intelligent disease recognition and diagnosis. Analyze using deep learning models. The third layer is virtual restoration and digital reproduction. Restoration is carried out using artificial intelligence technology. The research also discussed the current challenges faced. And specific implementation suggestions were put forward. It is suggested to establish an interdisciplinary collaboration mechanism. It is suggested to improve the construction of digital archives. It is suggested to develop intelligent auxiliary tools. This system provides a systematic solution for the protection of the murals in Yongle Palace. It helps to achieve scientific protection and sustainable inheritance of cultural relics.
