    • An optical communication module is provided with a platform to provide an accurate axial alignment with optical transceiving subassemblies. In the optical communication module, axes of the optical transceiving sub-assemblies are aligned by virtue of previously established axial alignment of the platform, and the platform is fixed to a main body by inserting an insertion jaw of a cover into an insertion groove formed on an upper surface of the platform. After the optical transceiving subassemblies are inserted into the platform having the axial alignment required for a system, a bonding agent is filled into spaces defined in the platform, thereby preventing the axes from deviated by an external force. The optical communication module allows for easier and more accurate guidance of a connection between the optical transceiving sub-assemblies and the optical connector, thereby minimizing the optical loss, and preventing the patterns on the printed circuit board from being damaged due to the insertion and disconnection of the optical connector.

    • A method and system to enable a computer to estimate calibration parameters autonomously so that accurate stereopsis can be performed. The present invention automatically calibrates two or more cameras with unknown parameters with respect to a robot or robotic appendage (e.g., articulated robot arm) with a light source that can be turned on and off at one end. A pair of cameras (e.g., digital cameras) are positioned and aimed so as to give stereoptic coverage of the robot's workspace. The procedure determines the positions and orientations of the pair of cameras with respect to a robot (i.e., exterior orientations) and the focal lengths, optical centers, and distortion coefficients of each camera (i.e., intrinsic parameters) automatically from a set of known positions of the robot arm, and a set of images from the right and left cameras of the robot arm in each position as the light is turned on and off.
