    摘要: In one aspect, the present disclosure relates to a method for recognizing a broadcast digital pulse recognition tone in a beacon-based light positioning system. In some embodiments, the method includes capturing a digital image using an imaging sensor of an imaging device, identifying one or more regions of the digital image illuminated by one of one or more beacon light sources, determining a frequency content of each of the one or more regions, and determining a particular tone broadcast by the beacon light source illuminating a particular region using the frequency content of the particular region. In some embodiments, the imaging sensor has a frame rate and includes a rolling shutter, the rolling shutter having a sampling rate greater than the frame rate of the imaging sensor.
