Description
Technical field
The utility model relates to a kind of the earth instrument of surveying and mapping, particularly a kind of the earth plotting board based on laser range finder.
Background technology
See that in the earth exploration to the original mapping instrument of the most employing of the shape high-acruracy survey on ground, adopt progressively piecemeal measuring method, not only measuring speed is slow, and complicated as under the situations such as high mountain, river, swampland when ground, also is in peril of one's life.Existing a kind of metering system is to add to be located on the certain altitude by laser instrument to measure, and height is finished by the laser beam flying the earth below 3 meters.Because it is limited to add the height of laser instrument, therefore each floor area of measuring is little, and measurement will be repeatedly calibrated in mapping to large tracts of land ground shape.
Summary of the invention
The purpose of this utility model provides the earth plotting board based on laser range finder that a kind of suitable large tracts of land ground shape is surveyed and drawn, measuring speed is fast, precision is high.
The purpose of this utility model is to realize like this, a kind of the earth plotting board based on laser range finder, it is characterized in that: place laser range finder and mapping processor on mapping ground, laser range finder and mapping processor are operated in the mapping state, the telecontrolled aircraft remote control that the bottom is had a rotating mirror is in to the laser range finder optical axis vertically upward static relatively motionless, it is parallel when the rotating mirror of telecontrolled aircraft is static with mapping day water plane, the laser that laser range finder is sent is fed back into the luminous output face of laser range finder again behind rotating mirror, again give an order to telecontrolled aircraft by telepilot, the control module control rotating mirror of telecontrolled aircraft rotates along optical axis, the laser beam that laser range finder sends behind rotating mirror with the rotating mirror anglec of rotation to the mapping ground polishing, the laser polishing point on mapping ground produces scattering or reflected light, with same angle to the laser range finder backspace, receive the distance signal of the processing that laser range finder receives by laser range finder, the rotation angle chrominance signal of rotating mirror send the mapping processor to handle.
The most direct providing with the rotating mirror central point was the observation landform looks of reference point when the laser polishing point of the laser range finder that the distance measuring signal that described mapping processor obtains comprises twice to the distance of rotating mirror and rotating mirror to mapping ground, mapping processor were drawn ground elevation and distributed.
The order that the angle of described control rotating mirror is sent by the mapping processor is finished or is surveyed and drawn processor by the control module control of telecontrolled aircraft and with anglec of rotation notice.
The angle of described control rotating mirror is rotating mirror to be fixed on the motor shaft perpendicular to stepper motor the motor shaft deflection of stepper motor, the same deflection of rotating mirror by support member.
The utility model has the advantages that: owing on telecontrolled aircraft, add the mirror surface system, catoptron is controlled at certain angle and frequency is rotated, when the ground laser beam is got on the catoptron, catoptron can carry out large area space scanning to ground, when laser spots arrives ground, the scattered light on ground is fed back into the receiving system of ground planar laser again, is finished by ground receiving system, processing and amplifying system, mapping process software the high precision on ground is surveyed and drawn.Therefore, the floor area of one-shot measurement and the traffic altitude of telecontrolled aircraft have with, when telecontrolled aircraft during, when catoptron has 45 degree corners, can survey and draw the ground in 200 meters scopes of diameter at 100 meters.Realize the shape mapping of large tracts of land ground.
Description of drawings
The utility model is described in further detail below in conjunction with the embodiment accompanying drawing:
Fig. 1 is the utility model example structure synoptic diagram.
Among the figure, 1, laser range finder; 2, mapping ground; 3, telecontrolled aircraft; 4, rotating mirror; 5, mapping processor; 6, control module; 7, laser polishing point.
Embodiment
As shown in Figure 1, a kind of the earth plotting board based on laser range finder, place laser range finder 1 and mapping processor 5 on mapping ground 2, laser range finder 1 and mapping processor 5 are operated in the mapping state, telecontrolled aircraft 3 remote controls that the bottom had a rotating mirror 4 are in to laser range finder 1 optical axis vertically upward static relatively motionless, when the rotating mirror 4 of telecontrolled aircraft 3 is static with to survey and draw ground 2 surface levels parallel, the laser that laser range finder 1 is sent is fed back into the luminous output face of laser range finder 1 again behind rotating mirror 4, again give an order to telecontrolled aircraft 3 by telepilot, the control module 6 control rotating mirrors 4 of telecontrolled aircraft 3 rotate along optical axis, the laser beam that laser range finder 1 sends behind rotating mirror 4 with rotating mirror 4 anglecs of rotation to the mapping ground 2 polishings, the laser polishing point 7 on mapping ground 2 produces scattering or reflected light, with same angle to laser range finder 1 backspace, receive the distance signal of the processing that laser range finder 1 receives by laser range finder 1, the rotation angle chrominance signal of rotating mirror 4 send mapping processor 5 to handle.
The distance measuring signal that mapping processor 5 obtains comprises that the laser range finder 1 of twice arrives the distance of rotating mirror 4 and the laser polishing point 7 that rotating mirror 4 arrives mapping ground 2, and the most direct providing with rotating mirror 4 central points was the observation landform looks of reference point when mapping processor 5 was drawn the ground elevation distribution.The landform looks that while converses different observation stations with observation landform looks or ground elevation distribution according to reference point.
The angle of control rotating mirror 4 can be to be finished by the order that mapping processor 5 sends on the one hand, also can be control module 6 control of telecontrolled aircraft 3 and with anglec of rotation notice mapping processor 5, the former is more more convenient than the latter, do not need the control module 6 of telecontrolled aircraft 3 to finish complicated task, only need control the angle of rotating mirror 4 on request.
The angle of control rotating mirror 4 is that rotating mirror 4 is fixed on the motor shaft perpendicular to stepper motor by support member, the motor shaft deflection of stepper motor, rotating mirror 4 same deflections, back and forth spend deflections as stepper motor positive and negative 45, telecontrolled aircraft is at 100 meters height, the ground elevation that then once provides in 200 meters scopes distributes, and the precision that elevation distributes is relevant with the control accuracy of deflection angle.
