Hand held portable three dimensional scanner |
摘要 |
Embodiments of the invention may include a scanning device to scan three dimensional objects. The scanning device may generate a three dimensional model. The scanning device may also generate a texture map for the three dimensional model. Techniques utilized to generate the model or texture map may include tracking scanner position, generating depth maps of the object and generation composite image of the surface of the object. |

1. A method comprising:
capturing multiple images of a target in an image sensing array (ISA) at different focal settings;analyzing over a plurality of the images an intensity of light at a pixel corresponding to a point on the target; and
identifying one of a local maxima or minima of the intensity of light for the pixel to determine which image contains a substantially optimum focus for the pixel. |
