The discussion revolves around the types of lenses or prisms required for an image sensor to capture a 180-degree field of view, specifically to visualize a hemisphere. Participants explore various optical solutions, including potential distortions and the use of multiple lenses or cameras for image stitching.
Participants present multiple competing views on the types of lenses or systems that could achieve the desired field of view, and the discussion remains unresolved regarding the best approach.
There are limitations regarding the assumptions about distortion tolerance and the specific applications for which these optical solutions are intended. The effectiveness of the proposed solutions may depend on additional factors not fully explored in the discussion.
I did a Google Images search on 360 Degree Camera, and got lots of interesting hits. It looks like most of these systems use several lenses/cameras and stitch the images together:grahas said:What type of lens/prism would be needed to allow a image sensor to see 180 degrees, so the sensor could see a hemisphere. It doesn't matter if the input is distorted. I thought that a glass pyramid with a square base might work.
