Abstract
Abstract. This paper deals with a fusion of range and panoramic images, where the range image is acquired by a 3D laser scanner and the panoramic image is acquired with a digital still camera mounted on a panoramic head and tripod. The fused resulting dataset, called "textured range image", provides more reliable information about the investigated object for conservators and historians, than using both datasets separately. A simple example of fusion of a range and panoramic images, both obtained in St. Francis Xavier Church in town Opařany, is given here. Firstly, we describe the process of data acquisition, then the processing of both datasets into a proper format for following fusion and the process of fusion. The process of fusion can be divided into a two main parts: transformation and remapping. In the first, transformation, part, both images are related by matching similar features detected on both images with a proper detector, which results in transformation matrix enabling transformation of the range image onto a panoramic image. Then, the range data are remapped from the range image space into a panoramic image space and stored as an additional "range" channel. The process of image fusion is validated by comparing similar features extracted on both datasets.
Highlights
Today, there exist several methods for the purpose of visualisation and documentation of the culture heritage (Koska et al, 2013; Křemen et al, 2011; Musílek et al, 2001; Pavelka et al, 2008)
The most often used techniques for culture heritage documentation include all kinds of photogrammetric methods, 3D laser scanning and the panoramic photography
The last mentioned method can be with advantage combined with the 3D point cloud acquired with the 3D laser scanner and provide a new form of dataset – textured range image, which has several advantages
Summary
There exist several methods for the purpose of visualisation and documentation of the culture heritage (Koska et al, 2013; Křemen et al, 2011; Musílek et al, 2001; Pavelka et al, 2008). Each of these methods provides the opportunity to document an investigated object in a different way. The last mentioned method can be with advantage combined with the 3D point cloud acquired with the 3D laser scanner and provide a new form of dataset – textured range image, which has several advantages. The paper is divided into several sections which deal with the mentioned methods and with the process of the texture image creation.
