The beneficial effects of the utility model are that: the utility model discloses an optical axis offset error survey device, the optical imaging system is fixed in the optical test bench through fixing device, and through the position of center on the graduation indicator board of demarcating the optical imaging system, the demarcation of the volume of setting a camera the axle offset effectively, has accurately been realized for the offset of optical axis in the visual field center in the time of can demarcating out it and lie in the difference and zoom on the position, provides accurate reference numerical value for the optical axis offset correction of optical imaging system.
Description
Technical field
The present invention relates to a kind of light shaft offset error determine device, in particular, particularly relate to a kind of side-play amount first measuring optical axis in optical imaging system zooming procedure, then utilize the light shaft offset error determine device that the side-play amount measured in advance compensates in use.
Background technology
Optical imaging system, has been widely used in all trades and professions of society at present.Due to the impact of optical design error and machining error, in zooming procedure, there is the shift phenomenon of optical axis instability in imaging system.Because the consistance of optical axis exists error, the accurate aligning to target cannot be realized, and then affect next step operation of personnel, even mislead operating personnel, bring bad consequence.
Summary of the invention
The present invention, in order to overcome the shortcoming of above-mentioned technical matters, provides a kind of light shaft offset error determine device.
The determinator of light shaft offset error compensation of the present invention, is characterized in that: comprise mounting platform, stationary installation and graduation indicator board, described mounting platform is fixed on optical test bed, and stationary installation is fixed on mounting platform; Optical imaging system to be determined is fixed in stationary installation, and the plane crossing center, optical imaging system front end is reference plane, and graduation indicator board is positioned at the front end of reference plane and parallels with it.
The invention has the beneficial effects as follows: light shaft offset error determine device of the present invention, optical imaging system is fixed on optical test bed by stationary installation, by demarcating the position of center on graduation indicator board of optical imaging system, field of view center can be calibrated when it is positioned on different zoom position relative to the side-play amount of optical axis, achieve the demarcation to light shaft offset amount efficiently and accurately, the light shaft offset for optical imaging system corrects and provides accurately with reference to numerical value.
Accompanying drawing explanation
Fig. 1 is the structure principle chart of light shaft offset error determine device of the present invention;
Fig. 2 is the A direction view in Fig. 1;
Fig. 3 is the B direction view in Fig. 1.
In figure: 1 mounting platform, 2 stationary installations, 3 graduation indicator boards, 4 reference planes, 5 optical imaging systems.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the invention will be further described.
As shown in Figure 1, give the structure principle chart of light shaft offset error determine device of the present invention, shown mounting platform 1 and stationary installation 2 constitute frock test block, mounting platform 1 is fixed on optical test bed, stationary installation 2 and mounting platform 1 fix, and optical imaging system 5 is arranged in stationary installation 2.The front end face choosing optical imaging system 5 is reference plane 4, as shown in Figure 2, gives the direction view of the A in Fig. 1, and the center point P in initial point O and optical imaging system is all arranged in reference plane 4.Shown graduation indicator board 3 is positioned at the front end of reference plane 4, and to be advisable at a distance of 10 ~ 30m, graduation indicator board 3 parallels with reference plane 4.The corresponding point O ˊ of initial point 0 on graduation indicator board 3 on reference plane 4 can be found out by source of parallel light, and then obtain the corresponding point P ˊ of P point.
Light shaft offset error compensating method concrete steps of the present invention are as follows:
1) test site is as shown in Figure 1 put up.The scope of suggestion chosen distance D is between 10 meters to 30 meters.With screw, frock test block is fixed on optical bench, then will the optical imaging system screw of test is needed to be arranged on frock test block;
1) with the distance D between tape measure metope and camera window;
2) find the O ˊ on graduation indicator board by source of parallel light, and indicate its position.
3), after the position of O ˊ is found out, according to the coordinate information of P point in Fig. 2, the position of P ˊ can be marked.
4) centered by P ˊ, coordinate system is set up.
5) optical system is powered on, video camera is zoomed to most focal length XW position, to the spider position shown in computer in the enterprising row labels of graduation indicator board, and record its coordinate Q1 (X1, Y1).
6) video camera is zoomed to EW position, to the spider position shown in computer in the enterprising row labels of graduation indicator board, and record its coordinate Q2 (X2, Y2).
7) video camera is zoomed to W position, to the spider position shown in computer in the enterprising row labels of graduation indicator board, and record its coordinate Q3 (X3, Y3).
8) video camera is zoomed to M position, to the spider position shown in computer in the enterprising row labels of graduation indicator board, and record its coordinate Q4 (X4, Y4).
9) video camera is zoomed to N position, to the spider position shown in computer in the enterprising row labels of graduation indicator board, and record its coordinate Q5 (X5, Y5).
10) video camera is zoomed to the shortest position of EN, to the spider position shown in computer in the enterprising row labels of graduation indicator board, and record its coordinate Q6 (X6, Y6).
By above measurement, can record at each zoom position, the side-play amount of optical axis, and deviation angle, the corresponding relation of this deviation angle information and zoom position is write in the storer of The Cloud Terrace servomechanism, The Cloud Terrace servomechanism can when optical system carries out zoom operation again, auto-compensation light shaft offset amount, guarantees aiming at all the time of field of view center and target.
