METHOD OF REMOTE INSPECTION OF ELECTRIC CIRCUITS BY MEANS OF THERMAL-VIDEOCAMERA Russian patent published in 2005 - IPC

FIELD: optoelectronics.

SUBSTANCE: method of remote inspection of electric circuits consists of the following procedures: 1) filming of power line by thermal imaging scanner and digital camera, 2) storage of data in computer memory, 3) calculation of geographic and cartographic coordinates of pixels of scanner photograph, 4) geometric transformation of scanner image to cartographic projection, 5) receiving of new scanner image and recording it to computer memory. On the first frame and on new scanner image like objects are found and their mutual correlation functions are defined; arguments of the functions characterize location of objects. Errors in location of like objects are minimized and first frame with high spatial resolution is received and stored. The last portion of operation is repeated for ant subsequent frame of digital camera till putting the last frame of set into coincidence and set of frames is combined into one two-layered image with high spatial resolution at known temperature of objects presented on it.

EFFECT: color two-layered image with high spatial resolution.
