Abstract

The disclosure provides techniques for registering a camera into a map via a robot. A method for registering a camera into a map may include: collecting an observation of a calibration marker from an image captured by the camera, the calibration maker being attached to a robot capable of moving in a view of the camera; calculating, for the observation of the calibration marker, a transform T (camera, marker) between a camera frame of the camera and a marker frame of the calibration marker; obtaining, for the observation of the calibration marker, a transform T (world, robot) between a world frame of the map and a robot frame of the robot; and performing, when more than a predetermined number of observations of the calibration marker are collected during movement of the robot, a calibration process to calculate a transform T (world, camera) between the world frame and the camera frame based on the transform T (camera, marker) and the transform T (world, robot) for each observation of the calibration marker.
