Abstract
A position measuring apparatus instructs a first node to emit light by transmitting a first light emission pattern to the first node, instructs a second node to emit light by transmitting the first light emission pattern to the second node, when light emission following the instructed first light emission pattern is detected, and instructs the second node to emit light by transmitting a second light emission pattern that is different from the first light emission pattern, when light emission following the instructed first light emission pattern is not detected.
