Combining an Optical Image of an Object with a Radiometric one and Errors Estimation
An algorithm for combining images obtained in a combined optical-radiometric object observation system is described. The algorithm is based on combination of optical and radiometric image matrices, segmentation of optical image and transmission of radiometric image temperature to the optical image segments. An example of combining images is shown, from which it follows that the joint processing of optical and radiometric images makes it possible to observe the thermal image of objects with the spatial resolution of optical image while preserving the radio brightness characteristics of radiometric image of millimeter wavelength range. A comparative calculation of errors in determining the directions to the object of observation is carried out. A comparative assessment of errors of optical and radiometric systems is given, showing that in the conditions of considered example, the error in determining the spatial position of object's center at a known range using an optical system is ten times less than using a radiometric one. The concept of joint operation of two surveillance systems is proposed, which allows to increase the speed of radiometric system when forming the object's image by determining the object's center by using the optical system.
