In geometric optics, distortion is a deviation from rectilinear projection; a projection in which straight lines in a scene remain straight in an image. It is a form of optical aberration. See more Although distortion can be irregular or follow many patterns, the most commonly encountered distortions are radially symmetric, or approximately so, arising from the symmetry of a photographic lens. These radial … See more Radial distortion, whilst primarily dominated by low-order radial components, can be corrected using Brown's distortion model, also known as the … See more • Anamorphosis • Angle of view • Cylindrical perspective • Distortion • Texture gradient • Underwater vision See more Radial distortion is a failure of a lens to be rectilinear: a failure to image lines into lines. If a photograph is not taken straight-on then, even with a perfect rectilinear lens, rectangles will appear as trapezoids: lines are imaged as lines, but the angles between them are … See more • Lens distortion estimation and correction with source code and online demonstration • 3D modeling Lens distortion and camera field of view in CCTV design See more WebIAV has developed a patented method that is capable of measuring cylinder distortion with maximum precision – as a key to designing and configuring optimized piston-cylinder …
