Abstract
An augmented reality system having a light source and a camera. The light source projects a pattern of light onto a scene, the pattern being periodic. The camera captures an image of the scene including the projected pattern. A projector pixel of the projected pattern corresponding to an image pixel of the captured image is determined. A disparity of each correspondence is determined, the disparity being an amount that corresponding pixels are displaced between the projected pattern and the captured image. A three-dimensional computer model of the scene is generated based on the disparity. A virtual object in the scene is rendered based on the three-dimensional computer model.
Claims1
A system comprising:
- a light source;
- a camera;
- a memory;
- and
- at least one hardware processor coupled to the memory and comprising instructions that causes the system to perform operations comprising:
- causing the light source to project of a pattern of light onto a scene, wherein the pattern is periodic;
- causing the camera to capture an image of the scene including the projected pattern;
- determining a projector pixel of the projected pattern corresponding to an image pixel of the captured image;
- determining a disparity of each correspondence, the disparity being an amount that corresponding pixels are displaced between the projected pattern and the captured image;
- generating, by one or more processors, a three-dimensional computer model of the scene based on the disparity;
- and
- rendering a virtual object in the scene based on the three-dimensional computer model.
