Web8 de jan. de 2013 · The function computes projections of 3D points to the image plane given intrinsic and extrinsic camera parameters. Optionally, the function computes Jacobians - matrices of partial derivatives of image points coordinates (as functions of all the input parameters) with respect to the particular parameters, intrinsic and/or extrinsic. Web25 de dez. de 2015 · The perfect fisheye lens can be modeled as a sphere through which scene projections are described by two basic properties. First, the field of view encompasses steradians and produces a circular image so that distortions are symmetrical about the image center.
