Centre position, therefore the image that two camera lenses 1 gather be able to should align, if can not align, illustrate both not same
On one horizontal level, you can whether alignd, judged with the image of the first printing opacity test chart gathered by observing two camera lenses 1
Whether the optical axis of two camera lenses is in the same horizontal position.
Preferably, the test striped 311 that multigroup level is traversed is provided with the first printing opacity test chart 31, as shown in figure 4,
The first printing opacity test chart 31 can use glass to make, and form test striped 311 by modes such as laser irradiations thereon.Water
The succinct easily observation of the flat test striped 311 traversed, as long as checking that the image that striped 311 is tested in the two images shown side by side is
No alignment, so that it may whether two camera lenses 1 are determined in the same horizontal position, with reference to shown in figure 5 and Fig. 6, when there is camera lens shown in Fig. 5
During 1 light shaft offset situation, it is observed that dislocation horizontal stripe image as shown in phantom in Figure 6.
Further, it is also possible in the image of the first printing opacity test chart 31 gathered by comparing two camera lenses 1, striped is tested
Whether whether 311 length is consistent, to judge the optical axis of two camera lenses 1 on same vertical position.When being tested in two images
When the length of striped 311 is inconsistent, illustrate that the scope for the first printing opacity test chart 31 that two camera lenses 1 are observed that is different,
So the distance of two the first printing opacity of distance test charts 31 of camera lens 1 is different, i.e. it is poor that two camera lenses 1 exist on vertical position
It is different.
Certainly, the observation can be by eye-observation or by the progress such as image processing software more refinement
Micro- contrast processing, related image compares and treatment technology those skilled in the art are known or can obtain, no longer superfluous herein
State.
Preferably, with reference to figure 3, light source 32, parallel adjustment eyeglass, eyepiece 35, the are disposed with the first parallel light tube 3
One printing opacity test chart 31 and object lens 36；Wherein, parallel adjustment eyeglass includes the first speculum 33 and the second speculum 34, light source
