terrain
(ZL201010502051.6)
CN101975570
(A)—2011-02-16
The invention relates to a three-dimensional observation device for scouring terrain, belonging to the
field of terrain measurement and comprising a full-plane laser projector, an image collection device, a
terrain image calibration device, a host lifting device, a fixed support structure and a power supply
system, wherein the full-plane laser projector comprises a slot-shaped line type laser die set, a die set
micro-adjusting bracket, a baffle board, a cover board, a laser distance meter and a universal joint; the
terrain image calibration device comprises a spot type laser die set and a fixed supporting board; the
image collection device comprises a computer, a digital camera, a camera gravity positioning box and a
universal joint; the respective horizontal angle of the full-plane laser projector and the digital camera is
automatically adjusted through the universal joint under the self-weight action so that the full-plane laser
is in parallel to a horizontal plane; the principal optical axis of the camera is perpendicular to the
horizontal plane; and the host lifting device controls the lifting of the full-plane laser projector in a step
pitch setting mode. The integral set of the system has higher observation efficiency and precision, and is
suitable for the research on the aspect of terrain three-dimensional analysis in a river model test
