Abstract
The invention relates to an optical system adapted to take or project high-definition images with well corrected aberrations for the purpose of taking images from a 360 DEG panoramic scene on a cylindrical, conical or other three-dimensional surface or project such a three-dimensional display surface onto a 360 DEG field of view. Images from the 360 DEG panoramic scene are formed on a rotationally symmetric, three-dimensional image surface 3 . The optical system comprises at least one rotationally symmetric reflective surface 2 , the position of an entrance pupil 4s with respect to a sagittal section is different from the position of an exit pupil 4m with respect to a meridional section.
Description
technical field [0001] The present invention relates to an optical system, in particular to shooting images from all directions on a three-dimensional imaging surface such as a cylinder or a cone, or projecting a three-dimensional display surface such as a cylinder or a cone on an omnidirectional distance. The optical system of the display surface. Background technique [0002] Conventionally, when projecting images on a 360° screen, images from multiple projectors were connected and combined on the screen, or were projected using a wide-angle optical system such as a fisheye lens. As such conventional technologies, there are those described in Patent Documents 1 to 7.
