摘要： An optical communications beacon receiver including a camera for capturing a plurality of beacon images. The plurality of beacon images includes a beacon signal transmitted from a beacon transmitter. The beacon receiver also including processing circuitry configured for determining the state of the beacon signal for each of the plurality of beacon images based on the known pattern, at least one beacon image of the plurality of beacon images includes a beacon on state and at least one beacon image of the plurality of beacon images includes a beacon off state, comparing the at least one beacon image including the beacon on state to the at least one beacon image including the beacon off state, and determining a beacon location based on the comparison of the at least one beacon image including the beacon on state to the at least one beacon image including the beacon off state.

摘要： A method supported by a first terminal is provided herein. To implement the method, a camera of a first terminal performs two or more captures of two or more frames along a line of sight toward a second terminal. A controller of the first terminal manipulates the two or more frames to produce two or more interim images and analyzes the two or more interim images to track a beacon of the second terminal. The controller outputs coordinates with respect to the tracked beacon to a mirror package of the first terminal.
