![]() ![]() Fisheye distortion - commonly found in fisheye lenses, can be seen as an exaggerated form of barrel distortion.įor other distortions models, users can always resort to creating their own output-to-input mapping, as shown here.Polynomial distortion - encompasses a broad set of common lens distortions, such as barrel, pincushion, a mix of these, etc.The following types of distortion models are included: This makes it an important stage in certain computer stereo vision applications, such as depth estimation, where two cameras must have their optical axis level and parallel. The end result is an undistorted image that can optionally be reprojected into a second camera to allow, for instance, realignment of input camera's optical axis. ![]() The input image can have some level of distortion caused by the camera lens. VPI provides functions that, together with Remap algorithm, perform image rectification. ![]()
