Abstract
A billboard display method includes: capturing images of a scene near the screen by a number of time-of-flight (TOF) cameras, building three dimension (3D) models of the scene according to the images and the data about distances between points in the scene and the TOF cameras; checking the 3D models to determine whether there is a person nearby the screen; checking the 3D models to determine a relative position of the person to the screen upon the condition that there is a person nearby the screen; and controlling a media to be shown at a corresponding position of the screen according to the relative position of the person to the screen.
Claims11
A billboard display system comprising:
- a screen;
- a plurality of time-of-flight (TOF) cameras to capture images of a scene near the screen and obtain data about distances between a plurality of points in the scene and the TOF cameras;
- a processing unit connected between the TOF cameras and the screen;
- and
- a storage system connected to the processing unit and storing a plurality of programs to be executed by the processing unit, wherein the storage system comprises:
- a three dimension (3D) model building module to build 3D models of the scene according to the images of the scene and the data about distances between the plurality of points in the scene and the TOF cameras;
- a human detection module to check the 3D models obtained by the 3D model building module to determine whether there is a person near the screen;
- a position detection module to check the 3D models to determine a relative position of the person on the screen when there is a person near the screen;
- an order setting module to set an order that the position detection module detects the relative positions of two or more persons on the screen when there are two or more persons near the screen;
- and
- a controlling module to control a media to be shown at a corresponding position of the screen according to the relative position on the person of the screen.
