A Real-time Panoramic Stereo Imaging System and Its Applications
In the past omni-directional cameras have been designed by several researchers such as . The problem with using normal cameras for vision-guided navigation is that objects from behind or the sides cannot be seen, and are thus impossible to avoid collisions with. Yagi addressed this problem by placing a mirror surface vertically on top of a normal camera. Even though the quality of the resulting image was not suitable for tasks such as object recognition, the images could be used very effectively for detecting moving and static obstacles in the scene. A robot was built with this panoramic imaging system in Osaka, Japan, and the robot could autonomously navigate in an environment cluttered with obstacles. Variations of this system have been developed by several other researchers later on.
