Description
Technical field
The utility model discloses the calibration system of a kind of large-scale workpiece, belong to the technical field that large-scale workpiece is demarcated.
Background technology
In various specialty fields of measurement, image is increasingly advanced for the trend detecting object appearance, but is as digital camera
Or slr camera is universal, its shooting distortion for picture showing existing for image is more and more obvious, this thing caused
Body deformability, the collimation error and error in data etc. problem, brings more puzzlement to technical staff.
Utility model content
This utility model is in order to solve the technological deficiency that prior art exists, i.e. for close examination angle and the error in data of correction chart picture,
The utility model discloses the calibration system of a kind of large-scale workpiece.
The technical solution adopted in the utility model is as follows:
The calibration system of a kind of large-scale workpiece, including being arranged on the identity device of surface of the work, for measuring the spacing of identity device
From measurement apparatus, for gathering image collecting device and the data processing equipment of workpiece image, described measurement apparatus includes
Distance meter, described distance meter is provided with bracing wire end, and described distance meter also with start to measure button, stop
Only measure button to be connected with distance values display screen, described distance meter, image collecting device all with data processing equipment phase
Even.
Further, described identity device includes an identification strip being pasted onto surface of the work, on described identification strip
It is provided with in one-dimensional coding and black circle characteristic point, and the determination region that characteristic point is after one-dimensional coding.
Further, described image collector is set to a camera.
Further, described data processing equipment is single-chip microcomputer or a computer etc..
Scaling method of the present utility model, pastes four corner locations with large-scale workpiece surface by one-dimensional coding and index point；
Before carrying out large-scale workpiece image acquisition, utilize distance measuring unit to measure 4 characteristic points on its surface, determine four spies
Distance size between each two characteristic point in levying a little, after being measured and the most successively record preserves numerical value, completes big
The first step initial parameter that type workpiece image is demarcated is arranged；Utilize high definition camera that described large-scale workpiece surface is carried out shooting to adopt
Collection image, and the image captured by guarantee all includes four coding characteristic points；The image input of the large-scale workpiece gathered is counted
In calculation machine, and every piece image is processed.
Effect of the present utility model:
This scaling method have only to a camera with a distance meter, and considerably less personnel or amateur level, just
Workpiece image can well be demarcated, it is thus achieved that the visual effect of positive apparent direction and accurately precision, at follow-up image
Reason and graphical analysis lay the foundation.
The effect of the one-dimensional coding in this utility model is the positional information in order to be quickly found out index point on the surface of large-scale workpiece；
The effect of index point is to set initial value for image calibration；The distance between actual point measured by described distance measuring unit, carries
High measurement accuracy and calibration accuracy.
In this utility model its operation is easier, accuracy is higher, effect is more preferable.Binding experiment field assay, multiple for difference
For miscellaneous degree background, it has more preferable adaptability for the image calibration of big workpiece.
Accompanying drawing explanation
In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, below will be to embodiment or existing
In technology description, the required accompanying drawing used is briefly described, it should be apparent that, the accompanying drawing in describing below is this utility model
Some embodiments, for those of ordinary skill in the art, on the premise of not paying creative work, it is also possible to according to
These accompanying drawings obtain other accompanying drawing.
The structural representation of Fig. 1 distance meter；
The calibration structure schematic diagram of Fig. 2 large-scale workpiece；
The schematic diagram of the calibration system of Fig. 3 large-scale workpiece；
In figure: 1 distance values display screen, 2 start to measure button, 3 stopping measurement buttons, 4 distance meters, 5 bracing wire ends, 6,
7,8,9 one codings, 10,11,12,13 index points, 14 workpiece, 15 data measurement units, 16 cameras, 17 computers.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is described in detail:
As shown in Figure 1, Figure 2, Figure 3 shows, the calibration system of a kind of large-scale workpiece, including one-dimensional coding 6, one-dimensional coding 7, one-dimensional
Coding 8, one-dimensional coding 9；Index point 10, index point 11, index point 12, index point 13 and distance-measuring device 15, high definition
Camera 16 and computer 17.
Described distance-measuring device 15 includes that distance meter 4, described distance meter 4 are provided with bracing wire end 6, and described
Distance meter 4 also with start to measure button 2, stop measuring button 3 and distance values display screen 1 is connected,
Described distance meter 4, camera 16 are all connected with computer 17.
Wherein, one-dimensional coding 6, one-dimensional coding 7, one-dimensional coding 8, one-dimensional coding 9 are distributed in gathered large-scale workpiece 14
Upper left, lower-left, upper right, four angular direction of bottom right, and it is distributed in direction, corner as far as possible, four constituted with guarantee
Limit shape is sufficiently large, if demarcate the Large Graph picture of large-scale workpiece with less tetragon, then stated accuracy can reduce, and result is forbidden
Really；Comprising four one-dimensional codings in each image, four one-dimensional codings represent each partial information of large-scale workpiece successively,
