C. Attorney, Agent or FirmInternational ClassG01C 3/08 (20060101)AbstractA passive mobile rangefinder and stereo viewer having at least two image verting television cameras each mounted on spaced apart, remotely controlled mobile supports with synchronous drives for azimuth and elevation control. Ranging components associated with each television camera, with data links to remote locations, provide continuous baseline variation data. A baseline selector and mixer data analyzer direct the video signals from the selected pair of cameras to the remote viewing location. A rangemarker in the observer's field of view or electronic correlation techniques provide the range data.Field of SearchStenographic | |
