Design of stereo imaging system with a panoramic annular lens and a convex mirror

Panoramic stereo imaging system can not only provide panoramic images to obtain more information, but also obtain the depth information of the target object, and it has broad application prospects in robot navigation, road planning, and obstacle avoidance. A new panoramic stereo imaging system combined with a panoramic annular lens (PAL) and a convex mirror is proposed. It provides a large panoramic vision up to 360°× (30°∼150°) and, to the best of our knowledge, the entire FOV is the largest in the existing literature. Meanwhile, the stereo field of view is 35°.
