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.
Claims20
A method for stereography, comprising:
- defining, by at least one processor, perception values for a result of a stereographic image generating process based at least in part on parameters of an assumed viewing environment, the parameters comprising an eye separation ‘e’ between eyes of an observer perceiving the object image and a screen size parameter;
- selecting, by the at least one processor, mathematical algorithms for generating input parameters of the stereographic image generating process based on the perception values, wherein the input parameters include a horizontal shift ‘h’ and the camera interaxial distance ‘t’;
- 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 for a result of a stereographic image generating process based at least in part on parameters of an assumed viewing environment, the parameters comprising an eye separation ‘e’ between eyes of an observer perceiving the object image and a screen size parameter;
- selecting mathematical algorithms for generating input parameters of the stereographic image generating process based on the perception values, wherein the input parameters include a horizontal shift ‘h’ and the camera interaxial distance ‘t’;
- and
- generating the result using the stereographic image generating process and the input parameters.
A non-transitory computer-readable medium encoded with instructions that when executed by a processor, cause a computer to perform:
- defining perception values for a result of a stereographic image generating process based at least in part on parameters of an assumed viewing environment, the parameters comprising an eye separation ‘e’ between eyes of an observer perceiving the object image and a screen size parameter;
- selecting mathematical algorithms for generating input parameters of the stereographic image generating process based on the perception values, wherein the input parameters include a horizontal shift ‘h’ and the camera interaxial distance ‘t’;
- and
- generating the result using the stereographic image generating process and the input parameters.
