Photogrammetric Texture Mapping: A methodology of applying photorealistic textures on scanned dense points cloud data

Summary

The biggest technological improvement to archaeological documentation techniques in recent years has been the implementation of various 3D digitization technologies, such as Computer Vision Photogrammetry and 3D laser scanning. Laser scanning produces the most accurate geometrical data available today, but it lacks the ability to accurately capture textures and diagnostic coloration information. Photogrammetric data produces highly accurate photographic textures, but the geometric data tends to be less accurate than the laser scanned data.

In this paper, the authors present a new methodology that combine advantages of laser scanner and Computer Vision Photogrammetry; applying photorealistic photogrammetry textures on geometry of laser scanned 3-D digital models. This methodology allows archaeologists to have a 3-D digital model that possesses laser scan quality geometry with photorealistic textures. Furthermore, archaeologist can apply this methodology to various laser scan dataset which is from artifacts captured by FaroArm to landscapes captured by a multi-beam sonar.
