Embodiment Construction

[0029] attached figure 1 It is the present invention under traditional mode, and moment matching method is to process vertical stripe according to following process:

[0030] Since the vertical stripe noise is mainly caused by the inconsistency of the response function of each detection unit in the spectral response area, the original image generally has a vertical stripe distribution without periodicity. When the surface signal is relatively weak, this noise will be more obvious. Considering that noise is generally superimposed on the signal, the noise is separated according to the statistical results of the image on different scales;

[0031] Assuming that the scene detected by each detector is in an ideal situation with the same balanced radiation distribution, the change of the data recorded on the detector is linear with the gain coefficient and bias coefficient of radiation correction, and has shift invariance . If Ci is the i-th detection unit, then the spectral respo...

Abstract

The invention discloses a method for removing vertical stripes of an infrared image in real time by utilizing improved local moment matching, which is suitable for gun sights, gun sights and hardware of an uncooled infrared detector, in infrared movement hardware of the uncooled infrared detector, the image acquisition frame frequency is 50Hz, and according to the video frequency 25Hz which can be recognized by human eyes, the image acquisition frame frequency is 20Hz. Under the condition that the final output observation video frame rate is not influenced, the time domain algorithm processing advantage is carried out in combination with the infrared image, and the frequency is determined to be 50 Hz; the infrared movement hardware has a separation blade correction function, and can correct and compensate the heterogeneity of an infrared image; the infrared focal plane detectors share one amplifier in the same column; compared with the prior art, the method has the advantages that the vertical stripe noise of the infrared detector is filtered in real time on a machine core assembly of the uncooled infrared detector, and the infrared image detection capability is improved.

Description

technical field [0001] The invention relates to the technical field of infrared imaging, in particular to a method for removing vertical stripes of an infrared image in real time by using improved local moment matching. [0002] This algorithm is suitable for the gun sights and gun sights of uncooled infrared detectors. Through the method of local matching to remove the vertical stripes of infrared images, it can automatically remove the infrared detectors due to the existing manufacturing process level and materials in real time. Limitation, the stripe-shaped non-uniform noise caused by the incomplete response characteristics of each detector unit in the infrared focal plane array, thereby improving the infrared detection capability. Background technique [0003] Uncooled infrared detectors have been widely used in sights and other observation instruments. However, due to the limitations of the existing manufacturing process level and materials, the infrared focal plane ad...
