Abstract

 Augmented Reality (AR) which extends an environment with virtual objects has been studied extensively and has gained popularity in landscape assessment. However, existing AR approaches cannot correctly simulate views after the demolition and removal of outdoor buildings. To resolve this problem, Diminished Reality (DR) has been paid attention. DR is a technique which can remove the image of an existing object and paste the background image on the area of the diminished object in real time. It is well known that accurate registration of video camera's position and direction is quite difficult in AR or DR if it is used outdoors. On the other hand, a measurement technology of point cloud data by using 3D laser scanner has also been focused. Point cloud data can be measured in a wide-range scale such as a city or a country by using Mobile Mapping System (MMS) which is a laser scanner on a moving vehicle. Considering rapid progress of information technology in recent years, it is expected that we can get point cloud data of any place freely in near future. The registration methods using point cloud data for AR have been studied. Therefore, in this research, a Diminished Reality simulation system using point cloud data was proposed. This system facilitates landscape simulation and assessment of demolition and removal of outdoor buildings beforehand.
