Measurement Field

In infrared imaging, a “measurement field” refers to a specific area within the thermal image that is chosen for detailed analysis. This area can be defined by the user to focus on particular parts of the image where temperature measurement or monitoring is important. The measurement field allows for targeted temperature data collection and processing, and it often sends this temperature information to other systems. In thermal image processing, measurement fields are also known as regions of interest (ROI).

Measurement fields can take various shapes, such as rectangles, circles, polygons, or free-form areas, depending on the software’s capabilities and analysis requirements. Once defined, the software can isolate and process the thermal data within this region separately from the rest of the image. Defining multiple measurement fields is especially useful in applications where inspections of multiple areas are needed, or to locate hotspots in electrical equipment within a specific area, monitor critical zones in manufacturing processes, or assess specific parts of a structure for thermal anomalies.
