    摘要: A method of transforming an input image from a hemispherical source to an output image in rectilinear coordinates is disclosed. The method includes receiving data representative of an input image originating from a hemispherical camera and having a size defined by an input image height and an input image width. Once the data is received, an output image width and output image height representative of a size of a rectilinear output image is calculated based on the size of the input image. A rectilinear output image is then generated by mapping input image pixels to locations within the width and height of the output image, without reference to the optical characteristics of the hemispherical camera.
