Abstract:
The present invention relates to an apparatus and a method for estimating a moving path using light communication in real time. A server contained in the apparatus for estimating the moving path in real time of the present invention is configured to comprise an agent management unit to set agents and clients; a server communication unit to receive the management information of the agents according to a preset monitoring period; and a path prediction unit to predict a predicted path of the moving path of the clients based on the positional information of the clients tracked through a position determination apparatus having a light communication device and an image capturing device from the agents, which is included in the management information.
Abstract:
Disclosed are a method for estimating a dimming level, a method for processing a visible light signal, and an apparatus using the same. The method for processing the visible light signal according to an aspect of the present invention comprises the steps of: receiving the visible light signal including at least one pulse; estimating a pulse width of the visible light signal; estimating the dimming level of the visible light signal using the estimated pulse width; and demodulating the visible light signal using the estimated dimming level.
Abstract:
Disclosed are a DMX-VLC address processing method using a DMX-512 network and an apparatus using the DMX-512 network. According to the present invention, the DMX-VLC address processing method comprises: a step of receiving a DMX-512 packet; a step of determining whether the DMX-512 packet is included in a light step data using a start code of the DMX-512 packet; a step of processing the light data using an address recorded in the DMX-512 address unit of the DMX-VLC address included in the DMX-512 packet when the DMX-512 packet is included in the light step data; and a step of executing a non-light data process using the address recorded in the DMX-VLC extension address unit of the DMX-VLC address when the DMX-512 packet is not included in the light step data.
Abstract:
