Multiplane calibration [ ] Multiplane calibration is a variant of that allows one to compute the parameters of a camera from two or more views of a planar surface. Freedownload Midi Lagu Country. The seminal work in multiplane calibration is due to Zhang. Calibrates cameras by solving a particular that captures the homographic relationships between multiple perspective views of the same plane. This multiview approach is popular because, in practice, it is more natural to capture multiple views of a single planar surface - like a chessboard - than to construct a precise 3D calibration rig, as required by DLT calibration.

The following figures demonstrate a practical application of multiplane camera calibration from multiple views of a chessboard. Chessboard feature extraction [ ] The second context in which chessboards arise in computer vision is to demonstrate several canonical algorithms. In, one seeks to identify image, which summarize the semantic content of an image and, hence, offer a representation of one's data. Chessboards - in particular - are often used to demonstrate feature extraction algorithms because their regular geometry naturally exhibits local image features like edges, lines, and corners. The following sections demonstrate the application of common feature extraction algorithms to a.
