Description
Technical field
The utility model relates generally to the device field demarcated using gridiron pattern camera, refers in particular to a kind of no color differnece polishing
The gridiron pattern caliberating device of mode.
Background technology
In image measurement process and machine vision applications, the demarcation of camera parameter is all unusual the key link, its
The precision of calibration result and the stability of algorithm directly affect the accuracy that camera work produces result.Therefore, camera mark is carried out
Surely it is the premise for carrying out follow-up work, improves the emphasis place that stated accuracy is research work.Camera calibration method has：Traditional phase
Machine standardization, active vision camera calibration method, Camera Self-Calibration method.And more generally traditional camera standardization, and
Gridiron pattern is a calibrating template being used in traditional camera demarcation, and during demarcation, the irradiating angle of light source is to shine
Most important factor in bright mode, spectrum are that the glow color of light source is equally the important content of light-source system design.Test table
Bright, surface is that the object of white is not required light source colour；If body surface colored is it is necessary to according to the selection of the color on surface
The big light source colour of contrast, monochromatic light should be selected as far as possible to avoid aberration in illumination.
In conventional gridiron pattern demarcation, the mode of polishing has natural light, or area-structure light.However, the list of natural light
Colourity is relatively low, easily produces aberration, and the photophore of area-structure light is costly.
Utility model content
The technical problems to be solved in the utility model is：In view of the deficienciess of the prior art, provide a kind of structure letter
The gridiron pattern caliberating device of single no color differnece polishing mode compact, cost is cheap.
In order to solve the above technical problems, the utility model uses following technical scheme：
A kind of gridiron pattern caliberating device of no color differnece polishing mode, including light source and gridiron pattern, in addition to baffle plate and use
To adjust the governor motion at gridiron pattern angle of inclination, the light source is line-structured light transmitter, and line-structured light transmitter is located at chess
The top of disk lattice and it is aimed downwardly, the gridiron pattern is installed on governor motion, and the baffle plate is installed on tessellated top,
A long trough loophole parallel with gridiron pattern is offered on the baffle plate, the light that the line-structured light transmitter is sent is through thoroughly
Unthreaded hole is irradiated in gridiron pattern surface.
As further improvement of the utility model, the governor motion includes base and the hinge being fixed on base,
The gridiron pattern is connected on hinge.
Compared with prior art, the utility model has the advantage of：The utility model uses the line-structured light being easily obtained
Transmitter carries out polishing, cheap；Gridiron pattern is tilted by suitable angle by governor motion, sends out line-structured light transmitter
The light gone out is approximately parallel to gridiron pattern and is radiated at gridiron pattern surface after passing through loophole, so that light is uniformly paved with whole chessboard
Lattice, so, the light being incident upon on gridiron pattern are the monochromatic light of high-purity, avoid the generation of aberration.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Marginal data：1st, line-structured light transmitter；2nd, gridiron pattern；3rd, baffle plate；31st, loophole；4th, base；5th, hinge.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments, it is noted that this practicality
New protection domain is not limited merely to following embodiments, on the premise of the utility model principle is not departed from, to this practicality
New made any improvements and modifications, are regarded as the scope of protection of the utility model.
As shown in figure 1, the gridiron pattern caliberating device of no color differnece polishing mode of the present utility model, including light source, gridiron pattern
2nd, baffle plate 3 and for adjusting the governor motion at the angle of inclination of gridiron pattern 2.Light source is line-structured light transmitter 1, and line-structured light is sent out
Emitter 1 is located at the top of gridiron pattern 2 and is aimed downwardly, and gridiron pattern 2 is installed on governor motion, and baffle plate 3 is installed on gridiron pattern 2
Top, offer a long trough loophole 31 parallel with gridiron pattern 2 on baffle plate 3, the light that line-structured light transmitter 1 is sent is worn
Cross loophole 31 and be irradiated in the surface of gridiron pattern 2.
Preferably, governor motion includes base 4 and the hinge 5 being fixed on base 4, and gridiron pattern 2 is connected on hinge 5.
Gridiron pattern 2 can be rotated upwardly and downwardly by hinge 5 with respect to base 4.
In use, first opening line-structured light transmitter 1, the smooth surface that line-structured light transmitter 1 is sent is set to pass through loophole 31
The surface of gridiron pattern 2 is radiated at, the angle of inclination of gridiron pattern 2 is then adjusted by governor motion, makes smooth surface to be approximately parallel to chess
The angular illumination of disk lattice 2 allows light to be uniformly paved with whole gridiron pattern 2, so, the light being incident upon on gridiron pattern 2 on the surface of gridiron pattern 2
It is the monochromatic light of high-purity, so as to avoid the generation of aberration.
