Adopt this kind of structure, three -dimensional laser scanning appearance mark target can be connected with the total powerstation base, can accurate counter point through total powerstation base counter point device, guaranteed the counter point precision of mark target with known position to, its simple structure is workable, and the installation is dismantled conveniently.
Description
Technical field
The utility model relates to a kind of three-dimensional laser scanner target, belongs to mapping instrument technology field.
Background technology
Three-dimensional laser scanner is a kind of by the method for high-rate laser scanning survey, and the three-dimensional coordinate data on quick obtaining measurand surface, large area high-resolution ground is set up the instrument of the 3-dimensional image model of object. The scanning result of three-dimensional laser scanner is directly shown as a cloud, utilizes these spatial point cloud data, can Rapid Establishment complex structure, the three-dimensional visualization model of irregular scene, not only save time but also laborsaving. As new high-tech product, three-dimensional laser scanner is successfully applied in the fields such as historical relic's protection, urban architecture measurement, mapping, mining industry, deformation monitoring, factory, large scale structure, pipe design, aircraft shipbuilding, road and rail construction, Tunnel Engineering, bridge reconstruction.
In the time of actual measurement, need in scene, arrange target, the cloud data that spatial digitizer is obtained carries out registration. The existing scanner target structures that are threaded that adopt, form some position by magnet base more, cannot be connected with traditional total powerstation target base, to it, precision are affected greatly. Scanner target is the datum mark of whole Scan orientation, improves its positioning precision and can improve work quality, guarantee point cloud precision.
Summary of the invention
The purpose of this utility model is: the problem existing for above-mentioned prior art, a kind of three-dimensional laser scanner target being connected with total powerstation base is provided, can be accurately to point to point apparatus by total powerstation base, ensured target and known point position to a precision, and, its easy processing simple in structure, easy installation and removal. In order to reach above object, the technical solution of the utility model is as follows: a kind of three-dimensional laser scanner target, comprise the support bar of reflector plate, supporting reflex sheet, and described support bar bottom is tubulose, has internal thread; It is characterized in that: described support bar bottom is provided with counterpart, and described counterpart top has joint, and bottom has sleeve pipe; Described joint is connected by connecting rod with sleeve pipe, and described joint is connected with support bar bottom thread, and described casing pipe sleeve is connected in the pedestal column of total powerstation base umbo, and described counterpart is coaxial with support bar and pedestal column. Support bar bottom just can convenient be connected with the pedestal column on total powerstation base after counterpart is set.
Further, the internal diameter of described sleeve pipe is than the large 0 ~ 0.2mm of the external diameter of described pedestal column. This number range can make the convenient socket of sleeve pipe, can ensure again the axiality of sleeve pipe and pedestal column.
Further, the diameter of described joint is greater than the diameter of described connecting rod. The diameter of described joint is than the large 8mm of the diameter of described connecting rod. Connecting rod diameter is less than joint, and joint can screw in support bar bottom completely, has improved the bonding strength between the two, prevents that support bar from rocking.
Further, described nipple tip is shaped with chamfering around. The structure of chamfering make assembling be more prone to, and can play reduce stress concentrate, the effect of reinforced joint intensity.
Further, the screw thread specification on described joint is 5/8 " UNC screw thread.
The utility model has the advantages that: this three-dimensional laser scanner target can be connected with total powerstation base, can be accurately to point to point apparatus by total powerstation base, ensured target and known point position to a precision, and its easy processing simple in structure, easy installation and removal.

Detailed description of the invention
In order to understand better the utility model, below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is elaborated.
Embodiment mono-
As depicted in figs. 1 and 2, the three-dimensional laser scanner target of the present embodiment comprises the support bar 2 of reflector plate 1, supporting reflex sheet, and support bar 2 bottoms are tubulose, have internal thread. Support bar 2 bottoms are provided with counterpart, and counterpart couples together support bar 2 and the pedestal column 4 of total powerstation base 5 umbos. Counterpart top has joint 3-1, and bottom has sleeve pipe 3-3, and the two connects by connecting rod 3-2. Joint 3-1 surface have with support bar on the external screw thread that matches of internal thread, its top one circle is shaped with chamfering. Internal thread and external screw thread specification are 5/8 " UNC screw thread. The structure of chamfering make assembling be more prone to, and can play reduce stress concentrate, the effect of reinforced joint intensity. The diameter of connecting rod 3-2, than the little 8mm of the diameter of joint 3-2, adopts this design, and joint just can screw in support bar 2 bottoms, strengthens the bonding strength between the two, prevents that support bar 2 from rocking. Sleeve pipe 3-3 is socketed in the pedestal column 4 of total powerstation base 5 umbos, and its internal diameter is than the large 0.2mm of the external diameter of pedestal column 4, the two matched in clearance. Counterpart is coaxial with support bar 2 and pedestal column 4, ensures that axiality can improve the precision to point between three.
In addition to the implementation, the utility model can also have other embodiments. All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop in the protection domain of the utility model requirement.
