Abstract
Disclosed is a method of detecting a shooting direction and apparatuses performing the method, the method including calculating a crossed angle between an object and a shadow of the object in an image and detecting a shooting direction of a shooting apparatus used for capturing the image based on the crossed angle and a reference angle corresponding to a time and a position at which the image is captured.
Claims20
A method of detecting a shooting direction, the method comprising:
- calculating a crossed angle between an object and a shadow of the object in an image;
- and
- detecting a shooting direction of a shooting apparatus used for capturing the image based on the crossed angle and a reference angle corresponding to a time and a position at which the image is captured.
A shooting direction detecting apparatus comprising:
- a collector configured to acquire an image from a shooting apparatus used for capturing the image;
- and
- a shooting direction analyzer configured to calculate a crossed angle between an object and a shadow of the object in the image and detect a shooting direction of the shooting apparatus used for capturing the image based on the crossed angle and a reference angle corresponding to a time and a position at which the image is captured.
