A process for the contactless determination of a two-dimensional temperature turin - formation, and infrared - measuring system

摘要

It is a process for the contactless determination of a two-dimensional temperature information (12) of a scene (14) by means of an infrared - measuring system (10) is proposed, which has at least the following process steps:• Measurement of infrared radiation from a solid angle range φ (30) by means of an infrared - detector array (54) of the infrared - measuring system (10), which consists of a large number of for infrared radiation sensitive pixels (62) is,• Determining a two-dimensional temperature information (12) of the measured infrared radiation,• Determining a distance information (36) between the infrared - measuring system (10) and of the scene (14) by means of a and (34) of the infrared - measuring system (10),• Correcting the two-dimensional temperature information (12) by a distance-dependent measurement errors.According to the invention, the distance information (36) as a two-dimensional distance information (36), in particular a distance map (36a), at least partially in the solid angle range φ (30) is determined, from the infrared radiation is measured, wherein said two-dimensional temperature information (12) by a distance-dependent measurement errors space angle is corrected dissolved.Furthermore, a corresponding infrared - measuring system (10) is proposed.
