Abstract
Structured light is projected onto an object, and an image of the object as illuminated by the projected structured light is captured. Reference object points are identified within the captured image, and the structured light projected onto the object is modified based on the identified reference object points. An additional image of the object as illuminated by the modified projected structured light is captured, and additional reference object points are identified within the captured additional image.
Claims15
A non-transitory computer-readable data storage medium storing program code executable by a processor to perform processing comprising:
- projecting structured light onto an object;
- capturing an image of the object as illuminated by the projected structured light;
- identifying reference object points within the captured image;
- modifying the structured light projected onto the object based on the identified reference object points;
- capturing an additional image of the object as illuminated by the modified projected structured light;
- and
- identifying additional reference object points within the captured additional image.
A method comprising:
- projecting, by a light source, structured light onto an object;
- capturing, by a camera, images of the object as illuminated by the projected structured light;
- identifying, by a computing device, reference object points within the captured images of the object;
- and
- modifying, by the computing device, the structured light projected onto the object based on the identified reference object points as the images are captured and the reference object points are identified within the captured images.
A head-mounted display (HMD) comprising:
- a light source to project structured light onto a wearer of the HMD;
- a camera to capture images of the wearer as illuminated by the projected structured light;
- and
- a processor to recursively identify reference points within the captured images and modify the structured light projected onto the wearer based on the identified reference points.
