Abstract
A reference image of the field of view in a reference state of illumination is obtained. The display is controlled to display a first image to the object to cause the field of view to be in a first state of illumination different from the reference state of illumination. A first captured image of the field of view in the first state of illumination is then obtained. Based on the reference image and the first captured image, a position of the display relative to the object is determined
Claims20
A computer-implemented method for determining a position of a display relative to an object within a field of view of the display, the method comprising:
- obtaining a reference image of the field of view in a reference state of illumination;
- controlling the display to display a first image to the object to cause the field of view to be in a first state of illumination different from the reference state of illumination;
- obtaining a first captured image of the field of view in the first state of illumination;
- and
- determining a position of the display relative to the object based on the reference image and the first captured image.
A computer program product for determining a position of a display relative to an object within a field of view of the display, the computer program product comprising a computer readable storage medium having program instructions embodied therewith, the program instructions executable by a processing unit to cause the processing unit to perform a method comprising:
- obtaining a reference image of the field of view in a reference state of illumination;
- controlling the display to display a first image to the object to cause the field of view to be in a first state of illumination different from the reference state of illumination,
- obtaining a first captured image of the field of view in the first state of illumination;
- and
- determining a position of the display relative to the object based on the reference image and the first captured image.
A system for determining a position of a display relative to an object within a field of view of the display, the system comprising:
- an interface adapted to obtain a reference image of the field of view in a reference state of illumination and to obtain a first captured image of the field of view in a first state of illumination different from the reference state of illumination;
- a display controller adapted to control the display to display a first image to the object to cause the field of view to be in the first state of illumination;
- and
- a calculation unit adapted to determine a position of the display relative to the object based on the reference image and the first captured image.
