METHOD AND DEVICE FOR SELECTION OF GROUND AND AIR OBJECTS (MODIFICATIONS) Russian patent published in 2001 - IPC

FIELD: selection of ground and air objects. SUBSTANCE: method consists in forming of a visible image of a section of the terrestrial surface, its discretization according to the space coordinates, tuning of video signal amplification and drift, its conversion to a digital form, storage of the digital image, forming of the frame with the analysis port, scaling and filtration of the stored digital image within the frame, estimation of image separability, tuning of the structure and parameters of the object (target) selector, bayes' and structural classification of image, forming of the structural current specimen and standard of the target, their correlative classification (referencing), estimation of the significance of each method for classification and their combination, integration of the target dimensions and coordinates with due account made for the significance of the method for classification, determination of the current or predicted target coordinates and their use in off-line operation for selection and tracking of a dimensional target. For selection and tracking of a small-size target a cluster analysis, segmentation and morphological classification of image are carried in the second modification of the method instead of the bayes', structural and correlative classifications of image. In the third modification of the method a similar processing of images obtained in different spectra of radiation is simultaneously accomplished. The first and second modifications are realized in a device having an optoelectronic sensor, units for preliminary processing of video signal and processing of digital image, selector of dimensional targets (bayes', structural and correlative classifiers) and a selector of small-sized targets (morphological classifier), units for estimation of the classification significance, integration of target coordinates and dimensions, decision making units. Due to the reconstructed structure, the device provides for lock-on and automatic tracking both of dimensional and small-sized targets. The second modification of the device has n identical channels similar to that described above, but operating from different spectrozonal optoelectronic sensors. The results of selection in the channels are integrated in the unit of interchannel coordinate integration with due account made for the significance of each selection channel. EFFECT: enhanced accuracy and reliability of selection of ground and air objects. 15 cl, 18 dwg
