Title:
METHOD AND APPARATUS FOR PREVENTING HEAT DAMAGE TO THERMAL IMAGING CAMERA
Document Type and Number:
WIPO Patent Application WO/2020/248761
Kind Code:
A1
Abstract:
A method for preventing heat damage to a thermal imaging camera, comprising: acquiring a thermal image of the thermal imaging camera; detecting whether the thermal image indicates that a high-temperature object exists in the screen of the thermal imaging camera; if so, generating a heat damage alert signal and if a blocking plate is currently not shut, shutting the blocking plate immediately, thereby avoiding the risk of permanent heat damage to a sensor due to direct exposure to an object emitting high-energy radiation. Also disclosed is an apparatus for preventing heat damage to a thermal imaging camera.
