Digital archive requires precise measurements of the shape, size, positioning, and other features of a cultural property. These measurements are critical to ensuring that cultural properties are properly preserved, researched, and restored. The generated data is also essential to creating high-quality Toppan VR productions.
The archive process generally begins with the collection of photographic images, surveys, and various kinds of measurements. Diagrams and photographs alone, however, cannot accurately capture all the complexities of a property’s form. Archive the ruins of megalithic structures, artifacts with decoratively curved surfaces, or statues with sublime expressions calls for a more sophisticated approach.
Toppan takes precise three-dimensional geometric measurements of cultural properties to create high-quality digital archives and Toppan VR productions.
Three-dimensional geometric measurements are commonly required for product design, quality assessment, and other industrial applications. Measurement precision, a priority in these applications, can be achieved by attaching hard measuring probes directly onto target objects or applying measurement powders, index markers, or other measurement treatments over target surfaces. Methods like these can seriously damage precious cultural properties.
Toppan recognizes the paramount importance of preserving cultural properties by gentle, non-destructive methods. That’s why Toppan applies non-contact, optical measurement methods using laser light and pattern projection to achieve safe, highly precise three-dimensional digital archiving.
