Different panomorph lenses

The term panomorph derives from the Greek words pan meaning all, horama meaning view, and morph meaning form. A panomorph lens is a particular type of panoramic lens that is part of the hemispheric wide-angle lens family. These lenses have 360 degree coverage with enhanced resolution adjusting pixel density in predefined zones of interest.[1]

The concept of panomorph lenses consists of creating better optical performance in zones of interest and matching sensor anamorphic ratio. The origin of panomorph technology dates back to 1999. The idea was conceived by a company named ImmerVision.[2] Several years after its creation, panomorph lenses have become a viable alternative to fisheye and catadioptric lenses.

Two important parameters for the panomorph lens are the amount and location of the resolution. These parameters, introduced at the optical design stage, allow the panomorph lens to provide a higher resolution in a defined zone than any other standard panoramic imager. By choosing between the use of anamorphosis and/or significant controlled optical distortion,[3] an increased number of pixels in a targeted area are achieved. Panomorph lenses are designed with specific object to image mapping function, making it possible to use algorithms to de-warp an image and correct distortion while maintaining a higher number of pixels in the zone of interest.
