Title: PROCEDURE FOR HYPERSPECTRAL IMAGE ANALYSIS IN REAL TIME
Abstract:
In this patent application, a comprehensive approach for applying hyperspectral image analysis in an efficient and simple way to measure chemical and structural characteristics of different objects, is presented. A hyperspectral image contains per pixel a spectral wavelength profile with several hundred variables, to be compared with a conventional color image with each pixel consisting of three values, one for red, green, and blue respectively. The procedure describes a methodology that is non-destructive and that to some degree can offer an attractive solution for replacing costly and time-consuming lab measurements. The procedure can even be applied to perform measurements in real time in a production setting. Statistical analysis is applied to use the hyperspectral information to measure chemical content and structural features. The analysis procedure can be roughly divided into a calibration step in which a statistical model system is built up to provide support for the classification and quantification in the next step, the prediction step in which the model system is used for performing measurements. The patent document describes for the invention important solutions for making the procedure. The described solutions addresses, among other important global issues for the concept, methodology for the statistical procedure for the large amounts of data and to maximize the accuracy of predictions, and finally technical solutions to make it feasible performing measurements in real time.
