Brief description of the use of a thermal camera, a device for implementing it, and a thermal camera incorporating such a device

摘要

The invention proposes a method of use of a thermal camera (100), comprising the steps consisting in: a) be cooled (31) the thermal camera; b) (32) for the production of a condition of stabilization of the parasitic radiation of the thermal camera; c) acquire (33) a first image (51) and acquire (35) a second image (52) of an observed scene; d) calculate (36), an image difference (53) by taking the difference between the second image (52) and the first image (51); e) to treat (37) the difference (53).
