Abstract: Systems and methods of generating a synchronized media content presentation using a plurality of media output systems communicably coupled to a respective plurality of network connected platforms are provided. A first network connected platform receives an IEEE 802.1AS master timing signal generated by “Grand Master” timing circuitry disposed in a second network connected platform. IEEE 802.1AS application service circuitry disposed in the first network connected platform determines an offset between a local timing signal and the receive master timing signal. Talker circuitry disposed in the first network connected platform synchronizes a media content presentation to the master timing signal and communicates a media/master timing signal synchronization signal to each of the network connected platforms. The media/master timing signal synchronization signal includes data representative of a media start location and a media start time referenced to the master timing signal.

Abstract: A method for re-localization of the robot may include retrieving, for each of keyframes in a keyframe database of the robot, image features and a pose of the keyframe, the image features of the keyframe comprising a global descriptor and local descriptors of the keyframe (210); extracting image features of a current frame captured by the robot, the image features of the current frame comprising a global descriptor and local descriptors of the current frame (220); determining one or more rough matching frames from the keyframes based on comparison between the global descriptor of each keyframe and the global descriptor of the current frame (230); determining a final matching frame from the one or more rough matching frames based on comparison between the local descriptors of each rough matching frame and the local descriptors of the current frame (240); and calculating a pose of the current frame based on a pose of the current frame based on a pose of the final matching frame (250).
