STUDY OF PLENOPTICAL REGISTRATION OF LOW-CONTRAST DISTANT OBJECTS

The features of detection of subtle objects by plenoptic optical-electronic systems (POES) are considered. Schemes and algorithms for generating POES images are presented to obtain information about subtle objects, taking into account the specifics of POES operation. The possibility of increasing the probability of detecting subtle objects is theoretically justified, which is confirmed by calculating ray tracing in POES. In the process of observing subtle, low-contrast samples of light objects on an external light background, the main provisions of the theoretical justification were experimentally confirmed. Taking into account the features of objects and the background, a set of algorithms for the analysis and detection of subtle objects has been formed, on the basis of which a methodology for their application and assessment of the reliability of detection of distant subtle objects has been developed. A comparative analysis of the results of detecting subtle objects by various OES is presented. The area of practical application of registration of POES of subtle objects is determined, as well as the degree of influence of various external and internal factors on the process of registration of POES of subtle objects of observation.
