Description
Technical field
The utility model relates to survey and draw, remote sensing monitoring field specifically designs a kind of for three-dimensional laser scanning system
Position target device.
Background technique
Three-dimensional laser scanning technique is the cutting edge technology that survey field is quickly grown in recent years, is had become after GPS
Another revolutionary character achievement after technology.Three-dimensional laser scanning system has the advantages that quick obtaining large area high-precision point cloud data,
It has been used widely in fields such as forestry, ecology, historical relic's protection, Geography monitors.But when measuring at the scene, generally require
Target device is applied to obtain additional coordinates information, so that the later period carries out cloud data registration.In the prior art, cylinder target
It is not excited angle of light limitation with it and is easy to the advantages that fixed and is used widely in three-dimensional laser scanning system.
The centre coordinate of cylinder target generallys use total station survey, i.e., is obtained using the edge that total station aims at cylinder target
Measurement data is taken, the centre coordinate of cylinder target is calculated in conjunction with body diameter and height, such method has the disadvantage in that the
One, there are the collimation error when total station aims at, precision is unable to get guarantee；Second, measurement efficiency is not high.
Therefore, in three-dimensional laser scanning system application process, using conventional method to the centre coordinate of cylinder target into
When row positioning, many errors and trouble can be inevitably had more.
Utility model content
In view of the deficiencies of the prior art, the purpose of this utility model is to provide a kind of positioning of three-dimensional laser scanning system to mark
Target assembly solves the problems, such as that cylindrical target centre coordinate is difficult to measure, and it is cumbersome also to solve the problems, such as that cylinder target loads and unloads.
Realizing the specific technical solution of the object of the invention is:
A kind of positioning target device for three-dimensional laser scanning system, it include tripod, support rod, cylinder target,
Connecting rod and GPS antenna.Wherein, support rod lower part is fixed with tripod, and support rod top is connect with cylinder target；In connecting rod
Portion is spirally connected with GPS antenna, and connecting rod lower part is connect with cylinder target；The cylinder target is cylindrical structure body, cylinder target
Outer surface is pasted with high-intensity reflecting film.
Preferably, the cylinder target is made of nylon rod；The support rod and connecting rod are made of aluminium alloy.
In order to guarantee the alignment of cylinder target and GPS antenna, to further increase cylindrical target central coordinate surveying essence
Degree, the utility model have done following improvement: the connecting rod is cylindrical-shaped structure body, and connecting rod top is provided with screw thread, screw thread
Size is matched with the threaded hole of GPS antenna；The cylinder target is cylinder type hollow structural body, and hollow parts and cylinder target are same
Axis, hollow parts diameter are identical as connecting rod；The support shank diameter is identical as cylinder target hollow parts diameter, under support rod
Portion is fixed with tripod.In practical operation, after the top screw thread of connecting rod and GPS antenna screw hole, it is mounted on cylinder
Target hollow parts can guarantee that cylinder target and GPS antenna center keep coaxial；Then directly the cylinder target can be installed
On support rod, achieve the purpose that support fixed cylinder target and GPS antenna.
In order to further increase the accuracy of three-dimensional laser scanning system positioning target device, the utility model is also done
It is following to improve: level(l)ing bubble device being installed in tripod, guarantees that cylinder target and GPS antenna are in horizontality always.
Technical solution provided by the utility model has the benefit that
(1) GPS antenna and cylinder target are combined into one by three-dimensional laser scanning system positioning target device, can be fast
Speed, accurate measurement cylinder Target Center coordinate.
(2) GPS antenna is mounted directly to cylinder target, and cylinder target is mounted directly on the support rod of tripod, is not necessarily to
Additional fixed, positioning target device handling are simple and convenient, can be by arranging that multiple devices improve 3 D laser scanning system
The Limit of J-validity and data precision of system.
