1. A simulated camera system, comprising:
memory storing instructions executed by a processor to generate a simulated camera in a simulated environment and obtain a distorted image using the simulated camera;
memory storing instructions executed by the processor to calibrate the simulated camera and obtain intrinsic parameters of the simulated camera by successive imaging of a repositioned target/marker generated in the simulated environment using the simulated camera; and
memory storing instructions executed by the processor to generate an undistorted image from the distorted image using the intrinsic parameters of the simulated camera.
