3D Reconstruction from Full-view Fisheye Camera

WebPreviously, action cameras were considered inappropriate for accurate 3D reconstructions due to radial distortion created by the wide angle of view (AOV) or fisheye lens. AOV is a function of sensor size and lens type and describes the angular extent of a camera's view. WebOct 13, 2024 · This paper proposed a method of three dimensions (3D) reconstruction from a wide field of view (FoV) camera system. This camera system consists of two fisheye cameras each with 180 ^ {\circ } FoV. The fisheye cameras placed back to back to obtain a full 360 ^ {\circ } FoV. WebWe present a telecentric lens that is able to gain 3D information. The proposed lens system has multiple aperture stops, which enable it to capture multidirectional parallel light rays, while a conventional telecentric lens has only one aperture stop and can capture only light rays that are perpendicular to the lens. We explain the geometry of the multiaperture … simscale crack download
