1. A method comprising:
receiving images captured of a target location comprising a plurality of light emitting devices, wherein each of the light emitting devices has an associated blinking pattern;
detecting the blinking pattern for each of the light emitting devices in the images, wherein the detecting comprises determining, for each of the light emitting devices, a gradient of an associated radius in the images over time;
determining a classification for each of the light emitting devices based on its detected blinking pattern; and
aligning a mobile platform with the target location based on the classifications of the light emitting devices.
