Abstract
Initiating a display screen for presenting information in a public environment. A camera is pointed toward the display screen is panned while capturing multiple image frames from the environment surrounding the camera. During the panning, respective pan and tilt angles of the camera are stored. The image frames and the respective pan and tilt angles are analysed to identify an image of the environment facing the display screen. An image sensor is associated with the display screen. An image feature captured from the image sensor is matched with an image feature captured from the camera of the environment facing the display screen.
Claims18
A method for initiating a display screen for presenting information, the method comprising:
- pointing a camera toward the display screen;
- panning the camera while capturing a plurality of image frames from the camera from an environment surrounding the camera;
- during said panning, storing respective pan and tilt angles of the camera respectively associated with capture times of the image frames;
- upon completing capture of the image frames, analysing the image frames and the respective pan and tilt angles to identify an image of the environment facing the display screen;
- wherein an image sensor is associated with and installed in the vicinity of the display screen or attached to the display screen;
- capturing image frames from the image sensor from a portion of the environment;
- and
- matching an image feature captured from the image sensor with an image feature captured from the camera of the environment facing the display screen.
A method for determining a viewing distance to a display screen, the method comprising:
- pointing the camera of a mobile device toward the display screen and presenting an image of the display screen on a display of the mobile device and determining screen size and orientation of the display screen from an image frame captured from the camera, or inputting a screen size and orientation of the display screen using an input mechanism of the mobile device;
- responsive to the screen size and orientation of the display screen, presenting on the display of the mobile device an outline associated with size and orientation of the display screen;
- while the mobile device is pointed toward the display screen and presenting an image of the display screen on the display of the mobile device, changing distance of the mobile device from the display screen until an image of the display screen matches the outline associated with the size and the orientation of the display screen.
A graphical user interface of a mobile device including or connected to:
- a camera and a display, the graphical user interface configured for determining a viewing distance from a display screen configured to present information, the graphical user interface comprising:
- a field for inputting a screen size and orientation of the display screen using an input mechanism of the mobile device or for presenting display screen size and orientation of the display screen;
- an outline associated with the display screen size and orientation of the display screen responsive to the screen size and orientation of the display screen;
- an image of the display screen superimposed on the outline;
- and
- an indication that the viewing distance is determined when the image of the display screen matches the outline.
