The cv::solvePnP()returns the rotation and the translation vectors that transform a 3D point expressed in the object coordinate frame to the camera coordinate frame, using different methods: 1. P3P methods (cv::SOLVEPNP_P3P, cv::SOLVEPNP_AP3P): need 4 input points to return a unique solution. 2. … See more The pose computation problem consists in solving for the rotation and translation that minimizes the reprojection error from 3D-2D point correspondences. The solvePnPand related functions estimate the object pose given … See more Refer to the cv::SolvePnPMethodenum documentation for the list of possible values. Some details about each method are described below: 1. cv::SOLVEPNP_ITERATIVE Iterative method is based on a … See more The cv::solvePnPGeneric()allows retrieving all the possible solutions. Currently, only cv::SOLVEPNP_P3P, cv::SOLVEPNP_AP3P, cv::SOLVEPNP_IPPE, cv::SOLVEPNP_IPPE_SQUARE, cv::SOLVEPNP_SQPNPcan … See more The cv::solveP3P()computes an object pose from exactly 3 3D-2D point correspondences.
