Abstract
Abstract. This paper presents the work accomplished in order to digitize and model the Winter Garden of the Earthenware Museum at Sarreguemines (Moselle, France). The objectives were to create a digital archive of this cultural heritage place and to find appropriate ways of promoting it. Topographic, photogrammetric and lasergrammetric methods were used to model the Winter Garden. Different virtual reality tools enabled us to spotlight some of its parts and to offer an immersive visualization. Several challenges had to be taken up during this project. We first had to find out the best processing workflow to model earthenware, which is a highly reflecting material. Image processing was also needed for aesthetic reasons and we finally had to find methods to reduce the size of the models.
Highlights
In 1880, the earthenware manufactory at Sarreguemines (Moselle, France) was a flourishing company, employing several thousands of workers and exporting its products throughout the world
Photogrammetric and laser scanning methods were used to build the 3D model of the Winter Garden
On the basis of its extensive experience in 3D laser scanning and photogrammetry recording (Grussenmeyer et al, 2016), the INSA Photogrammetry and geomatics Group team saw the key to success in the control of light conditions (Tucci et al 2015) and the homogenization of light to avoid specular reflections in photogrammetry (Nicolae et al, 2014)
Summary
In 1880, the earthenware manufactory at Sarreguemines (Moselle, France) was a flourishing company, employing several thousands of workers and exporting its products throughout the world. Winter gardens were in vogue at that time among wealthy people and Paul de Geiger, director of the manufactory, decided to build one in his private apartments. Nowadays, this room is a listed building and the heart of the city’s museum. This room is a listed building and the heart of the city’s museum This has led the town of Sarreguemines, on the initiative of Olivier Reis, to scan this local heritage jewel in the aim of creating a digital archive usable for touristic purposes. Beside the fountain (its most remarkable piece), the Winter Garden shelters vases, portraits of former directors, views of the city of Sarreguemines in late nineteenth century as well
