Abstract

L'invention concerne un procédé de mesure de la concentration d'un polluant atmosphérique ou aquatique. Le procédé comporte les étapes consistant à : (a) tester des variations de couleur basées sur la concentration d'un polluant contenu dans l'atmosphère ou dans l'eau à l'aide d'un kit de mesure colorimétrique ; (b) photographier la couleur du kit de mesure colorimétrique et la couleur d'une fiche de couleurs de référence à l'aide d'un dispositif de photographie pour obtenir une image ; (c) numériser les chromaticités de la couleur du kit de mesure colorimétrique et de la couleur de la fiche de couleurs de référence à l'aide d'un programme d'analyse d'images ; (d) et calculer la valeur de la concentration du polluant à partir de la valeur numérique de la couleur du kit de mesure colorimétrique à l'aide d'un procédé d'interpolation linéaire. Au moyen de la présente invention, il est possible de s'affranchir de la nécessité d'un coûteux équipement d'analyse distinct pour permettre une mesure sur site facile et économique. En outre, les couleurs du kit de mesure colorimétrique et de la fiche de couleurs de référence peuvent être obtenues sous la forme d'une image unique pour permettre une normalisation facile de l'image. De plus, les influences d'un environnement d'éclairage et des performances d'un dispositif de mesure peuvent être minimisées au cours du processus d'acquisition de l'image.
