Infrared image generation method, device and equipment and infrared thermal imaging system

Abstract

The invention discloses an infrared image generation method. The method comprises the steps of obtaining processed pixel data output by an infrared focal plane detector; determining a first mean valuematrix of the processed pixel data in the row direction and a second mean value matrix of the processed pixel data in the column direction; obtaining processed Dummy pixel data output by the infraredfocal plane detector; determining a third mean value matrix of the processed Dummy pixel data in the row direction and a fourth mean value matrix of the processed Dummy pixel data in the column direction; and generating an infrared image according to first array data determined by the processed pixel data, the first mean value matrix and the third mean value matrix and second array data determined by the processed pixel data, the second mean value matrix and the fourth mean value matrix. The method is convenient to implement, occupies few logic resources, is low in power consumption, and further improves the infrared image quality. Transverse and column line noises with relatively large amplitudes can be removed; and the data delay is small, and the pixel data output by the infrared detector is directly processed without depending on the effect of non-uniformity correction.

Description

technical field [0001] The present application relates to the field of optoelectronic technology, in particular to an infrared image generating method, device, equipment and infrared thermal imaging system. Background technique [0002] The infrared thermal imaging equipment system receives the infrared signal radiated from the surface of the object and performs a series of processing on the signal to obtain an infrared image. The focal plane detector is the key core device of the infrared thermal imaging equipment system, and its readout circuit usually shares the same output circuit with pixels in the same column or in the same row. Due to the influence of the process, the output circuits of the rows or columns are not completely consistent, resulting in incomplete bias voltages, and finally the infrared image contains non-uniform noise with horizontal stripes or column stripes as the main feature, called horizontal stripe noise Or streak noise. [0003] At present, in o...
