Description
Technical field
Close-range photogrammetry field is the utility model is related to, more particularly, to a kind of 8 points of volumes for close-range photogrammetry
Code mark.
Background technology
In close-range photogrammetry, due to testee surface characteristics unobvious itself, when from different perspectives, shooting is tested
Thing can obtain different images effect, it is difficult to treat location and put effectively being identified and be accurately positioned.Therefore, it is raising measurement accuracy
And reliability, it is often necessary to add artificial target on measured object and carry out subsidiary.Coding maker is to carry to uniquely determine volume
The artificial target of code information.When carrying out large complicated object measurement, because camera fields of view is limited, generally requiring shooting largely has
Overlapping photo carries out splicing the complete shooting that could be realized to object.Therefore, it is necessary on measured object or its week in measurement process
A large amount of coding makers are pasted on side, must be to the overlapping shooting in coding maker region when taking pictures.By to the automatic of coding maker of the same name
Identification, it is possible to achieve the adjacent quick splicing for having overlapping photographs.The coding maker mainly used at present is Schneider coding marks
Will and Hattori coding makers, but the coding sum of this two kinds marks is less than 500, it is impossible to meet to measure large-scale needs.
Xu Qing, Wang Dong etc. devise a kind of coding maker (Patent publication No based on color and architectural feature：CN 103033171A),
Wherein index point uses multiple color, makes complicated.Wear Hui Liang et al. and invent a kind of donut coding maker (patent disclosure
Number：CN 101261122A), coded number is 4096.The coding maker used at present in close-range photogrammetry, all only position
Function, to determine the dimension scale relation between photograph and material object, need to also separately station meter be used cooperatively to demarcate, not be suitable for not having
There is the close-range photogrammetry of station meter.
Utility model content
The purpose of this utility model be exactly in order to overcome above-mentioned prior art to exist the defects of and providing one kind can quickly know
Not, abundant 8 coding makers for close-range photogrammetry of accurate positioning, group/cording quantity, the function of station meter is also had concurrently.
The purpose of this utility model can be achieved through the following technical solutions：
A kind of 8 coding makers for close-range photogrammetry, including a mark plate and eight distributions are arranged at the mark
Index point on will plate,
In eight index points, index point 0,1,2,3 is to be that sequence forms four square summits clockwise, to institute
Square is stated by 6 × 6 grid divisions, index point 4 be located at index point 0, at the mesh point on 1 line, the distribution of index point 5,6,7
In on three mesh points of the square interior.
The mark plate is 49mm × 49mm square point-like coding makers.
The index point is a diameter of 5mm circular index point.
The mark plate includes the non-reflective rubber end liner of black, and the index point is sprayed on described black by white reflector material
The non-reflective rubber-sole lining of color is formed.
The mark plate also includes hard plastic board, and hard plastic board one side rubber end liner non-reflective with black is pasted
Connection, another side are provided with Double-face sucking disk.
Compared with prior art, the utility model has advantages below：
1) the utility model coding maker can realize 11500 kinds of codings, and group/cording quantity enriches；
2) the utility model uses 49mm × 49mm square point-like coding makers, compact structure；
3) the utility model has summit of four index points as a square, conveniently can pass through square target model principle algorithm
Its three-dimensional coordinate in camera coordinates system is calculated by this 4 points of pixel coordinates in imaging plane, and then obtains all eight marks
For will point in the three-dimensional coordinate of camera coordinates system, identification is quick；
4) the utility model sets an index point 4 to be easy to code identification between index point 0,1；
5) the utility model back side is provided with Minitype double-sided sucker, it is convenient to is adsorbed onto on measured object or its periphery, carries
The portability that high coding maker uses.
