Thermography camera configured for gas leak detection |
| abstract |
A portable thermography camera system ( 100 ) renders a video image of a survey scene over a narrow spectral bandwidth corresponding with an absorption band of a gas to be detected in the video image. The camera system forms a scene image onto a focal plane array ( 108 ) and generates a corrected image signal ( 162 ) corresponding with irradiance values at a plurality of locations of the scene image. The camera system further generates a temporally filtered image signal ( 168 ) corresponding with a temporal characteristics of the image signal ( 162 ) over a selected number of prior image frames. A difference block ( 166 ) reduces the temporally filtered image signal ( 168 ) by a scaling factor and produces a difference image by subtracting the scaled temporally filtered image signal from the corrected image signal ( 162 ). The displayed difference signal improves the visibility of the gas to be detected. |
