Description
Technical field
The utility model belongs to engineering measuring technology field more particularly to a kind of index point device.
Background technique
For the needs of construction safety, construction site is fitted with several monitoring cameras at present, and usually this monitoring is taken the photograph
As head be can be with all-directional rotation, for the purpose saved, utilized, we abandon traditional in the construction of road engineering
Measurement, modeling pattern can be applied to terrestrial photogrammetric survey and three-dimensional modeling for multiple with the monitoring camera of all-directional rotation, and
This application needs to establish an index point.
Utility model content
To solve the above problems, the utility model proposes a kind of index point device, the apparatus structure is simple, peace
It is convenient to fill, and is applied to terrestrial photogrammetric survey for monitoring camera and three-dimensional modeling provides important component part, make full use of
Existing device reduces construction cost, improves project benefit.
To achieve the goals above, the utility model uses following scheme, comprising:
The circumferential surface of uprightly the first upright bar of tubulose on the ground, the first upright bar upper end is equipped with tapped through hole；Circumferentially
Several braces being uniformly connected on the first upright bar circumferential surface, the other end connection of brace are embedded in the concrete component of subsurface；
Be inserted in the second upright bar that can be moved up and down in the first upright bar, the top of the second upright bar connects several support rods, support rod it is another
The inner surface of one end connection sphere；It is threaded into the bolt of the first upright bar tapped through hole, tapped through hole is stretched out in the front end of the bolt
Second upright bar is fixed.
The sphere is made of aluminum alloy flake.
When work, the position that several monitoring cameras can observe is arranged in a kind of index point device of the utility model
It sets.
The utility model structure is simple, install convenient, is applied to terrestrial photogrammetric survey and three-dimensional modeling for monitoring camera
Important component part is provided, existing device is made full use of, reduces construction cost, improves project benefit.
Detailed description of the invention
Fig. 1 is the utility model schematic view of the front view.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing, so that those skilled in the art can be more
Add and be clearly understood from, as shown in Figure 1, the utility model uses following scheme, comprising:
The circumferential surface of uprightly the first upright bar 1 of tubulose on the ground, 1 upper end of the first upright bar is equipped with tapped through hole；Along week
To several braces 2 being uniformly connected on 1 circumferential surface of the first upright bar, the other end connection of brace 2 is embedded in the concrete of subsurface
Component；It is inserted in the second upright bar 3 that can be moved up and down in the first upright bar 1, the top of the second upright bar 3 connects several support rods 4,
The inner surface of the other end connection sphere 5 of support rod 4；It is threaded into the bolt 6 of 1 tapped through hole of the first upright bar, before the bolt 6
Tapped through hole is stretched out at end, and the second upright bar 3 is fixed.
The sphere 5 is made of aluminum alloy flake.
When work, the position that several monitoring cameras can observe is arranged in a kind of index point device of the utility model
It sets.
The utility model structure is simple, install convenient, is applied to terrestrial photogrammetric survey and three-dimensional modeling for monitoring camera
Important component part is provided, existing device is made full use of, reduces construction cost, improves project benefit.
