Abstract
Disclosed herein are an apparatus, a method for measuring 3 dimensional positions of a viewer and a display device having the apparatus. The apparatus for measuring the 3 dimensional positions includes an image capturing module that photographs images included in objects; a detecting module that detects the objects from images photographed by the image capturing module and calculates sizes and coordinates of the images on the objects; and a position calculation module that calculates the 3-dimensional positions of the objects in the space in which the objects are positioned by using the information on the calculated sizes and coordinates of the image of the objects.
Claims14
An apparatus for measuring 3-dimensional positions of objects, the apparatus comprising:
- an image capturing module that acquires an image including an object;
- a detecting module that detects the object from the image acquired by the image capturing module and calculates sizes and coordinates of the object within the image;
- and
- a position calculation module that calculates the 3-dimensional position of the object in the space in which the object is positioned by using the following equations:
- Zd=(Fs×Ix)÷(2×Fx×tan(θx))
- Xd=(2×Zd×tan(θx)×Dx)/Ix
- Yd=(2×Zd×tan(θy)×Dy)/Iy
- where
- Xd, Yd, and Zd represent 3-dimensional coordinates within the space in which the object is positioned,
- Fs represents a reference horizontal size of the object stored in the position calculation module,
- Fx represents a horizontal size of the object within the image,
- Ix represents a horizontal size of the image,
- Iy represents a vertical size of the image,
- θx represents a horizontal angle of view of a camera used by the image capturing module to acquire the image,
- θy represents a vertical angle of view of the camera, and
- Dx and Dy are 2-dimensional coordinates of the object within the image.
