Perspective-n-Point
Perspective-n-Point (PnP) is the problem of estimating the pose of a camera given a set of n 3D points in the world and their corresponding 2D projections in an image. The camera pose consists of 6 degrees of freedom (DOF) which are made up of the rotation (roll, pitch, and yaw) and 3D translation of the camera with respect to an origin point in the world. This problem originates from camera calibration and has many applications in computer vision and other areas, including 3D tracking, robotics and augmented reality. A commonly used solution to the problem exists for n = 3 called P3P, and many solutions are available for the general case of n ≥ 3. A solution for n = 2 exists if feature orientations are available at the two points. Implementations of these solutions are available in open source software.
