Background technology
Three-dimensional laser scanning technique, also known as " outdoor scene reproduction technology ", sweep speed non-contact with its is fast, obtains information content
Greatly, the advantages that precision is high, real-time, full-automatic, complex environment measures, overcomes the limitation of traditional measurement instrument, becomes
Target with high precision three-dimensional data is directly acquired, and realizes the important means of three-dimensional visualization.
Large area deposit (such as dump, mound, ore storage, rubbish heap) is swept using three-dimensional laser scanner
It retouches, can be calculated with the three-dimensional coordinate of quick obtaining exhibiting high surface point, so as to accurately indicate the surface undulation of testee
Volume.Traditional measurement method is to measure deposit discretization of half-space surface point coordinates using total powerstation or GPS RTK, passes through drafting etc.
High line establishes the mathematical model on deposit surface, then calculates the volume of deposit, but because these deposit surface shapes are complicated,
The discrete point of measurement is limited, and part elevation can not be observed directly, can only be obtained by interpolation calculation.The method is not only time-consuming but also takes
Power is also difficult to realize sometimes；Photogrammetric calculating volume can also be used, but its precision is poor, while some deposits are same
Famous cake is to being difficult to determine.
However, being observed deposit using three-dimensional laser scanner, the three of bulk deposition object surface can be rapidly obtained
Dimension coordinate, measurement point is evenly distributed on deposit surface, therefore can quickly and accurately calculate volume.But domestic large size three at present
It ties up laser scanning cubing generally use manually or electric drive laser is completed to measure in track sliding, exist
Problems with：
1. can not need to realize that large torque Ultra-Low Speed (1~5 point turns 1 circle) steady high-precision is driven；
2. quickly starting or parking can bring shake；
3. unstable due to being driven, point cloud will appear random distortion, thus cause the data obtained inaccurate, and error is very
Greatly.
Invention content
The present invention is directed to problems of the prior art, provide it is a kind of realized by Worm Wheel System in the way of it is three-dimensional sharp
A kind of device of light cubing, it is desirable to provide survey that high-accuracy stable can be realized in port and pier three-dimensional laser cubing
Measure device.
To achieve the above object, technical solution provided by the invention is as follows：
It is a kind of to realize three-dimensional laser volume measurement device, including fixing axle, transmission component in the way of Worm Wheel System
And laser module；

The transmission component includes drive mechanism, pedestal and shell, and the drive mechanism is mounted on the base, the shell
It is fixed on or is removably mounted on pedestal.One end of the fixing axle is fixed on external component, for installing fixed be somebody's turn to do
Device, the other end are installed on the base by bearing.The laser module installation is on the shell.
The drive mechanism includes mainboard drive controller, stepper motor, endless screw support, shaft coupling, worm and gear.Worm screw
On endless screw support, endless screw support is fixedly connected with pedestal.The stepper motor drives worm screw rotation by shaft coupling, then
It drives worm screw to be rotated around worm gear by worm screw rotation, drives endless screw support, pedestal, shell to be rotated around worm gear by worm screw,
Thus laser module rotation is driven.Worm gear is screwed in the fixing axle by internal thread and is fixed by stop nut, and simultaneously
It is engaged with worm screw.
Further, the screw thread that the worm gear is engaged with worm screw is twill.
Further, the shaft coupling is immunity shaft coupling.
Compared with prior art, the present invention has the advantages that：
1. being driven with large torque Ultra-Low Speed (1~5 point turns 1 circle) steady high-precision；
2. solving the problems, such as quickly to start or stop in the flat-pushing laser measurement of rail mounted that shake can be brought；
3. it is continuously worm tooth when it is with worm gear tooth engagement since worm tooth is continuous continual helical tooth
The process of engagement, therefore stable working are not entered into and exit, impact, vibrations, noise are small, solve and are driven unstable, point cloud
It will appear random distortion problem；
4. installation is simple, measurement cost is significantly reduced, is saved the time, it is easy to use, and have a wide range of application, not only
In harbour cubing, in engineering detecting, deformation monitoring, historical relic's protection, forest and agricultural, medical research, the necks such as battlefield emulation
There is prodigious application space in domain.
