Abstract
A thermal imaging system includes an infrared camera, a user interface, and a processor. While an actuation of the user interface is detected, the processor is configured to apply non-uniformity correction (NUC) values to infrared image data in infrared images of a target scene; register the corrected infrared images using image stabilization; perform an image-stabilized optical gas imaging process using the registered infrared images to generate optical gas image data indicating a change in the target scene; and generate a display image including the optical gas image data. Actuation of the user interface may be detected while a depressible trigger is depressed, and no longer detected when the depressible trigger is released. Upon detecting the actuation of the user interface, the processor may perform a NUC process to establish the NUC values. A drift indicator in the display image may indicate movement of the infrared camera from a reference position.
