ALTIMETER USING IMAGING CAPABILITY |
| 摘要 |
An altimeter includes a laser projector for projecting a pattern onto a surface and a camera for viewing the projected pattern. An image processor is operatively connected to the laser projector and camera for determining distance to the surface based on cross-correlation of the projected and imaged patterns. The camera can be a short wave infrared (SWIR) camera. The projected pattern can be a pseudo-random, fixed pattern. |
