Abstract: In the present paper we describe the
developed analytical method of
calculation errors in determining the coordinates of the given points thermal images. These coordinate
attached thermal images can be used, for example, in remote diagnostics of
overhead power lines by determining
their hot spots, a sign of pre-emergency
state. An algorithm calculating a standard error of determining the coordinates of the given
points based on thermal images
of known errors in the measurement
of the primary influencing parameters
(coordinates and angular orientation of the
aircraft, etc.). A comparison of
errors obtained by an analytical
method with the results of estimates
of the errors produced by the method of statistical modeling, which confirmed the validity
of the results. Material reported at the 6th All-Russian
Conference "Radars
and communications".
Key words: Overhead power line, infra-red chamber,
