Variation.
The working principle of binocular calibration provided in this embodiment verifying device is illustrated below:
Referring to Fig. 1, this principle is mainly to pass through the laser reflection of laser level rule and reflecting mirror (or reflective mirror) to inclined
The amplification of firing angle is moved into, as a result compared with final error calibration.
Referring to fig. 2, the error of scaling board shows three directions, as yaw (Y-direction, Objects around A y-axis is rotated in figure),
Pith (direction P, object is rotated around x axis in figure) and roll (direction R, Objects around A z-axis is rotated in figure).Due to scaling board sheet
Body does not have rotary freedom after installing, so needing application method, always makes glasses by adjust spectacle plane three
Plane is parallel with calibration plane.The process of error correction analysis is introduced based on yaw, pitch.It should be understood that
Scaling board is corresponding with test target mounting platform, and eyes plane is corresponding with Devices to test mounting platform.
The correction at the angle yaw.Referring to Fig. 3, this mainly passes through laser level rule on the basis of Fig. 3 right back plate front
Face, with XZ plane at minute angle α, laser can be reflected back glasses when the reflective mirror of Laser emission to scaling board corresponding position
Correspondence reflective mirror at plane, and incident angle α β 1 is amplifying, after the amplification of several secondary reflections, laser is finally penetrated flat in glasses
Certain point on the numerical error thrust line in face.If scaling board and spectacle plane are there are when the deviation in the direction yaw, laser meeting
Thrust line or so is fallen in, or even exceeds error calibration region.By adjust glasses pedestal swivel slide (seeing below figure) with
Change laser facula in the position in error calibration region, falls in hot spot on vertical calibration line, rectifiable scaling board and eye
Deviation of the mirror plane on the direction yaw.Variance analysis schematic diagram is as shown in Figure 4.
The correction of the angle pitch.Referring to Fig. 5, this is similar with the angle yaw correcting principle, is with the upper surface of the bottom right Fig. 5 panel for base
Standard, with the direction YZ at minute angle β, after several secondary reflections, incident angle β 1 finally falls laser facula by amplification laser
On horizontal error calibration reference line.If scaling board and spectacle plane are there are when deviation on the angle pitch, laser can fall in base
Above and below directrix, deviation is too big even to exceed error calibration region.It, can be with by adjusting the β axis slide unit of glasses mounting seat
The position on reference line is fallen in by observation laser facula to correct the deviation of scaling board and spectacle plane on the direction pitch.
Variance analysis schematic diagram is as shown in Figure 6.
Arithmetic accuracy: schematic diagram Fig. 7 can be obtained according to optical path principle of reflection in optics.Deviation corner reflection amplification principle, such as Fig. 7
Shown, back and forth, the angle of deviation is put is twice (angle Yaw is as the algorithm of the angle pitch) to the every reflection one of laser.It is tested by laser reflection
Little deviation can be amplified to macroscopic multiple by the principle of the card angle of deviation, and round-trip number is more, and amplification effect is brighter
It is aobvious.
Theoretically, the minimum length range of human eye range estimation is 2mm, and laser facula can be transferred to 2mm, and the precision of the program is reachable
It arrives: when 2m measuring distance, trueness error 38.2um;When 50mm measuring distance, trueness error 1.186um.
Deviation precision arithmetic: as shown in fig. 7, the every reflection one of laser is back and forth, the angle of deviation, which is put, is twice (angle Yaw and pitch
Angle algorithm is the same).If scaling board is in angle upper deviation 0.1mm, corresponding sin (yaw/pitch)=0.1/200, yaw/
0.03 ° of pitch ≈, it is assumed that reflective mirror is sufficiently wide, and α is set to laser and reflects two when two pieces of reflective mirrors are at a distance of 2m back and forth, that
Final laser facula falls in reference-calibrating line position should be with reference line distance are as follows:
L (max)=2000* (sin (yaw)+sin (2yaw)+sin (3yaw)+sin (4yaw)) ≈ 10.467mm=
104.67*0.1mm
In the case where minimum test distance 50mm:
L (min)=50* (sin (yaw)+sin (2yaw)+...+sin ((4*2000/50) yaw))=50* ((cos (a/
2)-cos (N*a+a/2))/(2sin (a/2))) ≈ 50*6.748=337.385mm=3373.85*0.1mm, wherein N is sharp
Light number of turns.
Thus it proves, in the distance of 2m, deviation can be amplified 100 times or more by roundtrip twice, and identical mirror is grown 50mm's
Distance reflection can amplify 3373.85 times afterwards several times.
Theoretically, the minimum length range of human eye range estimation is 2mm, and laser facula can be transferred to 2mm, so the precision of the program
It can reach: when 2m measuring distance, trueness error 0.1/ (10.467/4)=38.2um;When 50mm measuring distance, trueness error
0.1/ (337.385/4)=1.186um.
The use process of binocular calibration provided by the invention verifying device is illustrated below:
Operator moves the pedestal under test target mounting platform 3 with hand push, makes in this binocular calibration verifying device front
It is moved on line slide rail 2;It projects downward vertically in measuring distance first laser source at planar side edge where test target
The laser rays distance scale ruler beaten on the table top of horizontal table 1 determine so that operator can will test mesh
Planar movement is to thinking experiment distance to be tested where mark;
The second laser source 41 on Devices to test mounting platform 4 is opened, laser is mapped to 45 ° of reflecting mirrors (i.e. the from laser source
One refracting telescope 45) on, then perpendicular to plane refraction where Devices to test to test target reflecting mirror in the plane, Zhi Houhui
It is reflected in plane where test target and the optical mirror where Devices to test in the two planes of plane, final laser
Devices to test institute can be fallen in the plane, and according to laser and Devices to test on laser detection graduated scale in the plane in
The position of calibration line is entreated to adjust the rotation position of Devices to test place plane, so that laser point is fallen on central calibration line.So
