Abstract
Mathematical relationships between the scene geometry, camera parameters, and viewing environment are used to control stereography to obtain various results influencing the viewer's perception of 3D imagery. The methods may include setting a horizontal shift, convergence distance, and camera interaxial parameter to achieve various effects. The methods may be implemented in a computer-implemented tool for interactively modifying scene parameters during a 2D-to-3D conversion process, which may then trigger the re-rendering of the 3D content on the fly.
Claims30
A method for stereography, comprising:
- defining perception values comprising a shape ratio and a width magnification factor for a result of a stereographic image generating process, in response to user input, wherein the perception values are based at least in part on an assumed viewing environment;
- selecting mathematical algorithms for determining input parameters of the stereographic image generating process, in response to the perception values;
- and
- generating the result using the stereographic image generating process and the input parameters.
A non-transitory computer-readable medium holding encoded instructions that, when executed by a processor, cause a computer to perform the operations of:
- defining perception values comprising a shape ratio and a width magnification factor for a result of a stereographic image generating process, in response to user input, wherein the perception values are based at least in part on an assumed viewing environment;
- selecting mathematical algorithms for determining input parameters of the stereographic image generating process, in response to the perception values;
- and
- generating the result using the stereographic image generating process and the input parameters.
An apparatus comprising a processor coupled to a stereographic camera input and to a memory, wherein the memory holds program instructions for execution by the processor to cause the apparatus to perform the operations of:
- defining perception values comprising a shape ratio and a width magnification factor for a result of a stereographic image generating process, in response to user input, wherein the perception values are based at least in part on an assumed viewing environment;
- selecting mathematical algorithms for determining input parameters of the stereographic image generating process, in response to the perception values;
- and
- generating the result using the stereographic image generating process and the input parameters.
