Problems solved by technology

[0002] In the infrared imaging process, due to various factors, the image non-uniformity will gradually increase, so it is necessary to improve the imaging uniformity through shutter correction; every time the shutter correction is performed, image rigidity is required, and it is impossible to observe real-time image;
[0003] In addition, the trigger conditions of infrared shutter are corrected according to time and temperature, which cannot reflect the degree of image degradation; often the shutter is not opened after image degradation occurs, or the shutter is opened without image degradation; so it is necessary to correct this problem solving

Embodiment Construction

[0038] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0039] Such as figure 1 Shown, a kind of infrared automatic shutter method comprises the following steps:

[0040] Step S1. The infrared detector performs infrared detection to generate infrared detection data;

[0041] Step S2. Collect the infrared detection data, and generate a detection image according to the collected infrared detection data;

[0042] Step S3. Evaluate the vertical stripes of the detection image by the image evaluation unit to obtain an evaluation value;

[0043] Step S4. When the evaluation value is greater than the set threshold, a trigger signal is generated;

[0044] Step S5. The shutter is opened according to the trigger signal, and the shutter is automatically corrected to adjust the im...

Abstract

The invention relates to an infrared automatic shutter opening system and an infrared automatic shutter opening method. The method comprises the following steps: S1, infrared detection is carried out to generate infrared detection data; S2, the infrared detection data are acquired, and a detection image is generated according to the acquired infrared detection data; S3, vertical stripes of the detection image are evaluated by an image evaluation unit to obtain an evaluation numerical value; S4, when the evaluation numerical value is larger than a set threshold, a triggering signal is generated; and S5, a shutter is opened according to the triggering signal, shutter correction is carried out, and the infrared detection imaging quality is adjusted. In comparison with the prior art, shutter opening is triggered according to the vertical stripes in image degradation, thereby being closer to a human sense, reducing the shutter error triggering probability and reducing manual shutter opening.
