摘要： A method for quantitative imaging of gas emissions utilizing optical techniques combining gas correlation techniques with thermal background radiation or gas self-emission radiation is presented. A simultaneous recording of images with and without filtering through a gas-filled cell is utilized for the identification of a selected gas. A new calibration method provides the display of the integrated gas concentration spatially resolved in the generated final image. The procedure includes methods for a correct subtraction of the zero level, consisting of self-radiation from the dual-image camera device including the as correlation cell and electronic offset, and for the calculation of the specific absorption as a function of the difference temperature between the background and the gas emission.

摘要： Automated localization of a point source of a visualized gas leak, by searching in a corner response function crf(x*,y*,τ), calculated based on a number of frames of said gas leak, for maximum values in the (x*,y*) variables that are stable over the time variable τ. Considering a point (x*,y*) as said point source if said corner response function crf(x*,y*,τ) has a maximum value in said point (x*,y*) and said point (x*,y*) is temporally stable.

摘要： Automated localization of a point source of a visualized gas leak, by searching in a corner response function crƒ(x*,y*,τ), calculated based on a number of frames of the gas leak, for maximum values in the (x*,y*) variables that are stable over the time variable τ. Considering a point (x*,y*) as the point source if the corner response function crƒ(x*,y*,τ) has a maximum value in the point (x*,y*) and the point (x*,y*) is temporally stable.
