Abstract

The utility model discloses an optical parameter timing device suitable for between CCD camera and objective, including the plummer, rectangle box and CCD subassembly are from left to right installed in proper order to the top of plummer, and the left side of rectangle box installs the CCD camera, and the latticed calibration fence of right side fixedly connected with of rectangle box, and the left side of CCD subassembly installs objective, the utility model relates to a CCD camera timing technical field that makes a video recording. This optical parameter adjusting device suitable for between CCD camera and objective, through being equipped with latticed calibration fence, the deformation center of the vertical and horizontal line of opposite square check pattern that CCD observed should be in the position placed in the middle and the symmetry of screen like this, if not the level position of placing in the middle, the deformation center of the square check pattern of observing can produce the skew, the picture produces the deformation, help the judgement whether because objective leads to the picture to warp not placed in the middle, and then do corresponding adjustment, readjustment thing or objective or CCD's vertical direction, calibration has been made things convenient for.

Description

Optical parameter adjusting device suitable for between CCD camera and objective lens

Technical Field

The utility model relates to a CCD camera timing technical field that makes a video recording specifically is an optical parameter timing device suitable for between CCD camera and the objective.

Background

CCD is a semiconductor imaging device, therefore has sensitivity height, anti highlight, distortion diminish, small, longe-lived, advantage such as anti-vibration, and during current maintenance CCD camera element, CCD photosensitive element and the objective of front end should keep the position placed in the middle, and be in relative vertical state with CCD photosensitive element, need to relapse the calibration many times, and is more consuming time and inconvenient, for this, the utility model provides an optical parameter timing device suitable for between CCD camera and the objective.

SUMMERY OF THE UTILITY MODEL

Not enough to prior art, the utility model provides an optical parameter timing device suitable for between CCD camera and the objective to solve the problem that proposes among the above-mentioned background art.

In order to achieve the above purpose, the utility model discloses a following technical scheme realizes: the utility model provides an optical parameter timing device suitable for between CCD camera and objective, includes the plummer, rectangle box and CCD subassembly are from left to right installed in proper order to the top of plummer, and the left side of rectangle box installs the CCD camera, the latticed calibration fence of right side fixedly connected with of rectangle box, and the left side of CCD subassembly installs objective, CCD photosensitive element is installed on the right side of CCD subassembly.

Preferably, the left side of the rectangular box is provided with a camera trepanning matched with the CCD camera, and the right side of the CCD camera extends to the inside of the rectangular box.

Preferably, the right side of the objective lens extends to the inside of the CCD assembly, and the left side of the CCD photosensitive element extends to the inside of the CCD assembly.

Advantageous effects

The utility model provides an optical parameter timing device suitable for between CCD camera and objective. Compared with the prior art, the method has the following beneficial effects:

this optical parameter adjusting device suitable for between CCD camera and objective, through being equipped with latticed calibration fence, the deformation center of the vertical and horizontal line of opposite square check pattern that CCD observed should be in the position placed in the middle and the symmetry of screen like this, if not the level position of placing in the middle, the deformation center of the square check pattern of observing can produce the skew, the picture produces the deformation, help the judgement whether because objective leads to the picture to warp not placed in the middle, and then do corresponding adjustment, readjustment thing or objective or CCD's vertical direction, calibration has been made things convenient for.

Drawings

Fig. 1 is a top view of the present invention;

fig. 2 is a perspective view of the rectangular box of the present invention.

In the figure: 1. a bearing table; 2. a rectangular box; 3. a CCD assembly; 4. a CCD camera; 5. a grid-like calibration bar; 6. an objective lens; 7. and a CCD photosensitive element.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-2, the present invention provides a technical solution: an optical parameter adjusting device suitable for a CCD camera and an objective lens comprises a bearing table 1, wherein a rectangular box 2 and a CCD assembly 3 are sequentially arranged at the top of the bearing table 1 from left to right, a CCD camera 4 is arranged at the left side of the rectangular box 2, a camera trepanning matched with the CCD camera 4 is arranged at the left side of the rectangular box 2, the right side of the CCD camera 4 extends into the rectangular box 2, a latticed calibration fence 5 is fixedly connected at the right side of the rectangular box 2, the left side of the CCD assembly 3 is provided with the objective lens 6, the right side of the objective lens 6 extends into the CCD assembly 3, a CCD photosensitive element 7 is arranged at the right side of the CCD assembly 3, the left side of the CCD photosensitive element 7 extends into the CCD assembly 3, the right side of the CCD photosensitive element 7 is connected with an external display device through a connecting line, and the latticed calibration fence 5 is arranged, so that the deformation center of a longitudinal line and a transverse line of an opposite square pattern observed by the CCD is in, if the square grid pattern is not in the centered and horizontal position, the deformation center of the observed square grid pattern can deviate, and the picture deforms, so that the image deformation is facilitated to judge whether the picture deforms due to the fact that the objective lens 6 is not centered, corresponding adjustment is further carried out, the object or the vertical direction of the objective lens 6 or the CCD is readjusted, and the calibration is facilitated.

And those not described in detail in this specification are well within the skill of those in the art.
