In this research, in order to solve the problems visually impaired persons have when they go out, we have developed a system which gives information on three-dimensional space to them by using image processing. As a method for efficiently inputting a three-dimensional space into the system, we took up the acquisition of images with a fisheye lens. So we conducted experiments to examine the usefulness of fisheye image input for general object detection algorithm. And we also performed experiments on the shortening of processing time with a view to mounting it on small devices. From the results, it was found possible, by correcting the distortion aberration, to use the fisheye image for the inputting of the algorism of object detection.
