Abstract: Techniques are disclosed to calibrate a camera for use with one or more robots to perform a robotic application. In various embodiments, selection of a camera to be calibrated is received via a user interface. A region of interest associated with the camera and a robot with which the camera is associated is determined. A set of sample points within the region of interest is selected. The robot is moved through a set of trajectories to position the robot, successively with respect to each of at least a subset of the sample points, in a predetermined pose at a location associated with the sample point and, at each location cause the camera to generate a corresponding image that includes at least a fiducial marker located on the robot. The respective predetermined poses and corresponding images are used to perform a set of calibration computations with respect to the camera.
