The autonomous research and development of the robot for collecting large data and ultra-high-precision image data of cultural heritage, using modern control technology, changed the conventional fixed filter into a selective multispectral cutoff filter, realized the acquisition of visible and uv-infrared spectrum images, and achieved a new way to small volume The precious cultural relics in the form of uneven concave and convex are collected by high efficiency and automatic collection of visible spectrum and near infrared spectrum with super-high resolution. The innovative technology of root searching and locating is adopted to collect the super high precision images of large scale, micro distance and three-dimensional cultural relics. It provides technical solutions for the acquisition of large data of cultural and historical data, with the acquisition accuracy of over 10 billion pixels per square meter, which meets the requirements of cultural relics material, structure, disease nondestructive testing and multi parameter simultaneous analysis. It provides efficient and non-destructive analysis means for digital data storage, value recognition, identification, disease analysis and evaluation of protection and repair effect.
