Abstract
In view of the progression of the Japanese super-aging society, ensuring the smooth movement of senior persons along pedestrian spaces presents an urgent challenge for all. Technological studies, such as those examining mobile information terminals for walking support, are underway to resolve this issue. Compilation of a 3D database of pedestrian spaces is indispensable for implementation of these technologies. For this study, we collected a 3D database of pedestrian spaces using a hand-cart-type Mobile Mapping System (MMS) while walking along pedestrian spaces. Although this database might include fewer fine data than those compiled by on-car type MMS, it provides a simple system for various purposes. Because a few earlier studies examined the fundamental performance of hand-cart-type MMSs, we instead examined the precision of measurements produced by the system and detected locations of blocks to guide visually impaired people. Those data might be used in a database supporting smooth movement by pedestrians. Furthermore, we assess future methods of compiling databases.
