The subject matter of the article is the method of searching for objects of interest by spectral features based on an active electro-optical system, in which a set of multispectral laser emitters is used as a radiation source, followed by computer processing of the received image. The goal is to develop a method of searching for objects of interest using an active optical-electronic system followed by computer processing of the received image. The tasks are: consideration of the features of construction and operation of active electro-optical systems with dynamic spectral processing; development of a method of searching for objects by spectral features using an active electro-optical system with computer image processing; development of a mathematical model that allows you to make a decision about the presence of an object of interest by determining the areas of the image with elements that have the highest brightness value. The methods used are: methods of digital image processing, methods of mathematical modeling, methods of optimization theory, analytical and empirical methods of image analysis after their digital processing. The following results were obtained. Features of construction and operation of active electro-optical systems with dynamic spectral processing are considered. A method of searching for objects by spectral features using an active electro-optical system with computer image processing has been developed. A mathematical model has been developed that allows you to make a decision about the presence of an object of interest by identifying areas of the image with elements that have the highest brightness value. Conclusions. The article develops a method that allows you to search for objects by spectral features with an active electro-optical system with computer image processing. A feature of the developed method is the application at the initial stage of an active electro-optical system for measuring the spectral reflectance of the studied area, which is subsequently used, together with the spectral characteristics of the object of interest, in the calculation of the hardware function (filter vector) to ensure an increase in the contrast of the image of the object interest. At the final stage, computer processing of the received image is carried out in order to determine the area where the object of interest is located, based on the elements of the image with the highest brightness value. Mathematical modeling of the developed method of searching for an object of interest in the observation area was carried out. According to the results of mathematical modeling, the decision about the presence of an object of interest was made for the areas whose constituent elements have the highest brightness indicators.Downloads
