Hot tool temperature analysis though infrared images

textile manufacture occupies a prominent place in the national economy. because of its importance researches have been made on the development of new materials, equipment and methods used in the production process. the cutting of textiles starts in the basic stage, to be followed by the process of the making of clothes and other articles. in the hot cutting of fabric, one of the variables of great importance in the control of the process is the contact temperature between the tool and the fabric. this work presents a technique for the measurement of the temperature based on the processing of infrared images. with this purpose, it was developed a system which is composed of an infrared camera, a framegrabber pc board and a software which analyses the punctual temperature in the cut area enabling the operator to achieve the necessary control of other variables involved in the process.
