INFRARED BEACON AND CONFIGURATION SYSTEM FOR CONFIGURING SAME

摘要

An infrared beacon 100 is provided which may be used in a localization system. The infrared beacon comprises an infrared emitter 110 for emitting infrared light, a light sensor 120 for measuring the amount of ambient light outside the infrared beacon,and a controller 130 for regulating the infrared visibility of the infrared emitter from outside the infrared beacon in dependence upon the measured amount of ambient light. By changing the infrared visibility in dependence upon the ambient light, the beacon has a more constant infrared visibility. Thus more detailed localization, less dependent upon ambient light levels, is possible.
