1. A master projector device, comprising:
a visible light sensor configured to detect a visible light wavelength band;
an invisible light sensor configured to detect an invisible light wavelength band;
at least one transceiver configured to communicate with a slave projector device;
a memory including a program including at least one instruction; and
at least one processor electrically connected with the visible light sensor, the invisible light sensor, the at least one transceiver, and the memory and configured to execute the at least one instruction of the program, wherein the processor is configured to:
obtain first sensing information obtained through the visible light sensor,
obtain second sensing information through the invisible light sensor,
generate a positional relationship with the slave projector device based on the first sensing information and the second sensing information, and
control a projection direction and projection range of the slave projector device based on the generated positional relationship and the second sensing information identified by the invisible light sensor while projecting an image stored in the memory to a projection surface.
