Abstract

La présente invention concerne un appareil de mise en place d'analyse, un appareil de traitement, un procédé de mise en place d'analyse et un procédé de traitement, qui appartiennent au domaine de l'analyse d'images thermiques. Dans l'état de la technique, quand différentes séquences de fonctionnement sont mises en place pour des régions à analyser, les parties d'un objet photographié de régions à analyser ayant un même nombre peuvent être incompatibles, ce qui est susceptible de rendre difficile le suivi de l'analyse. Grâce à l'appareil de mise en place d'analyse, à l'appareil de traitement, au procédé de mise en place d'analyse et au procédé de traitement, une région à analyser est déterminée en fonction d'une région sélectionnée, et des informations relatives à des informations de partie sont associées à la région à analyser. De cette manière, une région à analyser établie est facile à réguler, ce qui permet de résoudre le problème technique actuel.
