Abstract

The invention discloses a blind element search method for the noise of an infrared movement component. By obtaining the original data output by a detector array; determining the time noise matrix of each pixel according to the original data; performing median filtering on the time noise matrix to determine the median value The difference between the filtered matrix and the time noise matrix; determine whether the absolute value of the difference is greater than a preset threshold, and if so, determine that the pixel at the corresponding position is a noise blind pixel. This application uses the median filter of pixel temporal noise and the difference of temporal noise to search for noise blind pixels. After adding blind pixels, no flickering noise blind pixels can be seen on the image, which improves the imaging performance of infrared core components. In addition, the present application also provides an infrared core component noise blind element search device, an infrared core component, and a computer-readable storage medium with the above-mentioned technical effects.

Description

technical field [0001] The invention relates to the technical field of infrared detection, in particular to a method and device for searching blind elements of noise in infrared core components, an infrared core component and a computer-readable storage medium. Background technique [0002] The detector array is a pixel array composed of M rows×N columns. The domestic mainstream is 640×512 or 384×288. The temporal noise of the detector is used to evaluate the minimum resolution capability of the detector to the signal, and then evaluate the minimum accuracy of the detector to detect the temperature. [0003] The existing method for testing temporal noise is as follows: place the room temperature baffle in front of the detector, wait for the core temperature to stabilize; continuously collect 50 frames of detector output data matrix, and calculate the pixel temporal noise V by formula (1) n (i, j), unit mV: [0004] [0005] in: F is the total number of frames collect...
