1. A method for monitoring an inactive livestock, as a monitoring method for visualizing a location of an inactive livestock in a livestock pen, the method comprising:
extracting livestock objects from a video image acquired for each frame;
calculating center coordinates indicating a location of the inactive livestock based on coordinates of the extracted livestock objects; and
displaying an object icon representing the inactive livestock in a display region mapped to the calculated center coordinate among a plurality of display regions defined on a display screen; and
emitting light by light emitting units selected based on the calculated center coordinate, among a plurality of lighting units installed in a livestock structure,
wherein
the emitting of light by the selected light emitting units includes:
generating, by a lighting controller included in the video analysis device, a triangle area by connecting three coordinates selected from coordinates of the plurality of lighting units represented on a two-dimensional plane coordinate system,
determining whether the center coordinate exists in the triangle area; and
when the center coordinate exists in the triangle area generating a dimming control signal for controlling light emitting operation of three lighting units corresponding to the three coordinates.
