Algorithms for improving the image of the object in the infrared range

Представлено огляд похибок, що впливають на якість тепловізійного зображення. Показано, що використання псевдокольорового тепловізійного зображення замість монохромного дозволяє забезпечити краще сприйняття для аналізу зображення оператором. Представлено сучасні методи обробки телевізійних зображень, що можуть бути використані в тепловізійному - телевізійному каналі спостереженняOne of the main characteristics of the optoelectronic thermal imaging observing systems that determine the efficiency of solving targets by operator is the quality of the formed image. The quality of the image is largely linked to its resolution and precision of mapping boundaries (edges) of objects of interest. This paper presents an analytical overview of the errors that affect the quality of the thermal image. It is shown that the use of thermal pseudo color image instead of monochrome allows better perception to analyze the image by operator. Proposed and substantiated to use the blue-green range of colors for the image. Due to individual emotional characteristics of the human operator we provide the possibility for manual selection of colors of thermal image. In the application of thermal imaging device that is hardware generated to enhance the informativeness of image and improve their quality, it makes sense to use means of processing signals generated by photomatrix, namely: - Method of converting two-dimensional images in a discrete form, which makes it possible to obtain the transfer function of the receiver, which takes into account the size of the pixel, matrix size and fill factor of sensitive elements; - Method of increasing resolution of image by software methods; - Algorithms designed to detect faults in the matrix elements, which eliminates image artifacts; - Digital signal processing algorithms that allow compression and image segmentation, nonlinear filtering nois
