Abstract: The disclosure relates to a projector device and a method for controlling the same. A master projector device according to an embodiment may obtain first sensing information through a visible light sensor, obtain second sensing information through an invisible light sensor, generate a positional relationship with a slave projector device based on the first sensing information and the second sensing information, and control a positional relationship of the slave projector device based on the generated positional relationship and a coordinate value of an invisible indicator identified by the invisible light sensor while projecting an image stored in a memory to a projection surface.
