1. A display device comprising:
a display unit having a display panel and a camera;
a posture adjustment driving unit configured to adjust a posture of the display unit; and
a controller configured to:
control the camera to capture a first image of a viewer viewing the display unit when the display unit is positioned at a first height,
control the posture adjustment driving unit to move the display unit to a second height different than the first height,
control the camera to capture a second image of the viewer viewing the display unit when the display unit is positioned at the second height,
correct at least one of the first image and the second image based on orientation information of the display unit on capturing the first image and the second image,
generate a 3D body mesh of the viewer using the first image and the second image,
calculate a viewer-optimized display unit posture setting based on the 3D body mesh,
control the posture adjustment driving unit to move the display unit to a height corresponding to the viewer-optimized display unit posture setting,
calculate a first pixel distance between two feature points of the viewer from the first image and the second image,
calculate a first spaced distance from the camera to the viewer based on the first pixel distance between the two feature points of the viewer,
store data in a memory about the first spaced distance and the first pixel distance,
control the camera to capture a third image of the viewer,
calculate a second pixel distance between the two feature points of the viewer from the third image,
calculate a second spaced distance from the camera to the viewer based on the second pixel distance between the two feature points of the viewer,
control the posture adjustment driving unit to adjust the posture of the display unit based on the second spaced distance from the camera to the viewer,
determine if the viewer moved horizontally in the second image and the third image, and
store the data about the first spaced distance and the first pixel distance if a horizontal movement of the viewer in the second image and the third image is within a prescribed pixel distance.
