MEDIA DISPLAY SYSTEM AND ADJUSTMENT METHOD THEREFOR

摘要

An adjustment method for a media display system includes a time-of-flight (TOF) camera capturing an image of a scene in front of an electronic billboard and obtaining data about distances between a number of points in the scene and the TOF camera. Building a three dimension (3D) model of the scene. Checking the 3D model to detect a face region in the 3D model. Detecting a reference eyeline in the 3D model. Obtaining a midline of the 3D model. Comparing the reference eyeline with the midline to determine whether the two lines overlap and outputting a comparison signal correspondingly, and driving a driving apparatus according to the comparison signal to adjust height of the electronic billboard.
