Description
Technical field
The present invention relates to a kind of hidden point and measure target, belong to boats and ships mapping equipment technical field.
Background technology
In boats and ships, extra large work, steel construction construction applications, in the enforcement of the three-dimensional accuracy surveying work of boat segmental/total group section, there are some points to be blocked by barrier, form hidden point, cannot collect.If cannot gather, will cause the imperfect of three-dimensional segment data collection, thereby have influence on the analysis result of segmentation.
Summary of the invention
The object of the invention is to solve in boats and ships mapping operations, the problem that some hidden point cannot be collected, provides a kind of hidden point to measure target and solves the problems referred to above.
To achieve these goals, technical scheme of the present invention is as follows:
A kind of hidden point is measured target, comprise: target bar and the equidistant some target seats that are arranged on target bar, one end of described target bar is also provided with target point, on described target seat, be equipped with target disc, on described target disc, be equipped with reflector plate, on described reflector plate and target disc, be all carved with crosshair, and the crosshair on crosshair and target disc on reflector plate coincides, the cusp of the central point of the crosshair of described reflector plate and target point is located along the same line.
In the present invention, the diameter of described target bar is 10 ~ 20mm, and target bar is the manufacture of anti-bending material.
In the present invention, described reflector plate is circular reflector plate, and its diameter is 20 ~ 50mm.
In the present invention, the width of the crosshair on crosshair and reflector plate on described target disc is 0.3mm.
In the present invention, described target point is " 7 " font, and target point comprises horizontal sides and oblique flap, and described horizontal sides and each reflector plate are in same plane.
In the present invention, described target point adopts the antiwear wolfram steel manufacture of high strength.
In the present invention, on described target point, be also provided with U-shaped safety screen.
In the present invention, the distance of the center of reticule point on described adjacent two reflector plates is identical, and the distance that the center of reticule point of a reflector plate nearest apart from target point puts with the distance of target point and the center of reticule of described reflector plate the center of reticule point that is adjacent reflector plate is identical.
In the present invention, described target seat and target disc are all square, and four jiaos of target seat are respectively equipped with screw, and described target disc is fixed on target seat by screw.
In the present invention, reflector plate adopts diffuse reflection coating material.
Beneficial effect of the present invention is mainly reflected in: solved concealment point measurement difficult point, improved the precision of concealment point measurement, guaranteed three-dimensional segmentation/always organize the integrality that segment data gathers, guaranteed the precision of hidden point.
Accompanying drawing explanation

Embodiment
Referring to Fig. 1, Fig. 2 and Fig. 3, target bar 10 is manufactured by anti-bending material, its diameter is 15mm, the first target seat 21 and the second target seat 22 are arranged on target bar 10 by screw 50, one end of target bar 10 is also provided with high intensity tungsten steel making " 7 " character form structure target point 30, one end that target bar 10 is provided with target point 30 is also equipped with U-shaped safety screen 70, can when target is idle, cover on target point 30, prevent that target point 30 from stabbing staff, on the first target seat 21 and the second target seat 22, be respectively equipped with the first target disc 41 and the second target disc 42, on the first target disc 41 and the second target disc 42, being respectively equipped with diameter is circle the first reflector plate 61 and the second reflector plate 62 of 30mm, the first reflector plate 61 and the second reflector plate 62 surfaces all scribble diffuse reflection coating and are all carved with width the crosshair 611 and 621 that is 0.3mm, on the first target disc 41 and the second target disc 42, being also respectively equipped with width and being crosshair on crosshair (not shown) and the reflector plate of 0.3mm and the crosshair on target disc coincides, the center of reticule point A of the second reflector plate 62, the crosshair 611 central point B of the first reflector plate 61 and the cusp C of target point 30 are located along the same line, and the distance that the distance that A point is ordered to B and B point are ordered to C is 100mm, certainly, the distance that the distance that A point is ordered to B and B point are ordered to C is not limited to this numerical value.
Principle of work of the present invention is by hiding point, by polar coordinates principle, outwards to amplify, and the coordinate of hidden point is to calculate by the distance between the first target disc 41 on target bar 10 and the second target disc 42 and their coordinate figure.Concrete method is that the target point 30 of target bar 10 is aimed to hidden point, and target bar 10 is hidden point vertically, and surveying instrument is directly measured the first target disc 41 and the second target disc 42 on target bar 10.
Referring to Fig. 4, during use, target bar 10 is clamped in a universal steering gear 80, the magnet piece on universal steering gear 81 is fixed near mapped point, rotate the connecting rod 82 of universal steering gear, make target point 30 touch mapped point, start to survey and draw, while carrying out the mapping of next point, again rotate the connecting rod 82 of universal steering gear, make target point 30 touch corresponding mapped point, survey and draw.
The invention solves concealment point measurement difficult point, the measuring accuracy of concealment point can be brought up in 0.5mm, guaranteed three-dimensional segmentation/always organize the integrality that segment data gathers, antifatigue degree reaches more than 100,000 times; The light scene that is more suitable for is used; Thickness appropriately can be goed deep into all kinds of weld seams; Safety-valve is guaranteed the safety factor of using.
In sum, it is only preferred embodiment of the present invention, not be used for limiting scope of the invention process, all equalizations of doing according to the shape described in the claims in the present invention scope, structure, feature and spirit change and modify, and all should be included within the scope of claim of the present invention.
