Perspective-n-Point is the problem of estimating the pose of a calibrated camera given a set of n 3D points in the world and their corresponding 2D projections in the 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 the world. This problem originates from camera calibration and has many applications in computer vision and other areas, including 3D pose estimation, 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 also available in open so

  • También conocida como PNP o Perspective N-Points, es un problema que consiste en estimar la pose de una cámara calibrada a partir de un conjunto de N puntos 3D de coordenadas conocidas, y sus correspondientes proyecciones en la imagen de la cámara. La pose de la cámara tiene 6 grados de libertad, típicamente referidos como posición y orientación, donde la posición se expresa como coordenadas X, Y y Z en algún sistema de referencia dado, y la orientación como un conjunto de 3 rotaciones cartesianas. El problema proviene de uno mayor conocido como "calibración de cámara", específicamente de sus parámetros extrínsecos, y tiene numerosas aplicaciones en informática y robótica, como estimación de pose 3D o realidad aumentada.
