| The omni-directional vision, in other name is panoramic vision, of which the visual area could be more extensive than a hemisphere (360 °×180° ), acquires all visual information of the three-dimensional space once, is a popular and widely concerned new visual perceiving technology in recent years. Due to its' extensive visual area, it is getting more important to the fields in which decision is made depending on visual information, such as in civil, military and space exploring fields.Because the omni-directional vision is a new developing technology, its basic theory is still unripe now, and a lot of problems need to be solved too. According to the domestic and overseas current situation of the omni-directional vision, this thesis focused on the study of the omni-directional visual technologies and applications.First part, briefly introduced the existing methods of omni-directional vision imaging, derived theory model of the imaging system with a reflector which has a single view point, explained the physical essence that visual area could be extended by using a reflector with curved surface.Aim at the existing method that revert a panoramic image to a spread cylinder image, efficiency of calculation is analyzed, the original algorithm is revised, a new algorithm named twice quick reverting arithmetic is proposed. The number of calculation is reduced, and speed of reverting is advanced on the premise of not changing the effect of reverted image.In order to solve the problem that serious distortedness are remained in the spread cylinder image of a panorama ,when the reverting method is used in extensive space imaging, and substances are distributing in any direction, this thesis propose a new method named flat window imaging which is based on the main view point of reflector, designs the reverting algorithm. By using this algorithm, the distortedness in reverted image is improved. The results of...
