WebFisheye Calibration Basics. Camera calibration is the process of computing the extrinsic and intrinsic parameters of a camera. Once you calibrate a camera, you can use the image information to recover 3-D information from 2-D images. You can also undistort images taken with a fisheye camera. The Computer Vision Toolbox™ contains calibration ... WebFind many great new & used options and get the best deals for Canon EF 8-15mm f/4.0L Fisheye USM at the best online prices at eBay!

English: An illustration of a sensor-lens system imaging a point using the variable names from the Mapping function … A fisheye lens is an ultra wide-angle lens that produces strong visual distortion intended to create a wide panoramic or hemispherical image. Fisheye lenses achieve extremely wide angles of view, well beyond any rectilinear lens.
