| Research Abstract |
A space recognition system for the visually impaired needs to detect (1) effectively fine shapes, (2) the barrier factors in vertical direction desired to be detected early when approaching by walk, (3) obstacles being not suitable for detection by contact, etc. Downsizing of stereo imaging device that is a component of the space recognition system for the visually impaired became success. An original software engine, forming a core of information processing system as another component, that can calculate disparities from arbitrary stereo images in high speed and high reliability by using a DP matching regardless of imaging devices was created. Furthermore, expansion of spin-off (glasses-free multi-viewable three-dimensional displaying) into the medical field was tried. In consideration of return to society, the availability of the laser range finders instead of the special imaging devices that are on public sale was viewed.
