3 Terms and definitions

GB/T 12604.9-1996 established and the following terms and definitions apply to this standard. 3.1 Sensor element for sensing temperature in thermal imaging cameras. 3.2 The infrared camera responds to the wavelength range of infrared radiation. 3.3 The range of temperatures that the thermal imaging camera can reliably measure with accuracy. 3.4 The ability of an infrared camera to distinguish the details of an object's geometry in space. It is used with the infrared detector cell size area, the optical system System focal length and image quality, signal processing circuit bandwidth and so on. General detector angle can also be used pixel (DAS) or instantaneous field to represent. 3.5 Photographing a basic set of infrared spectroscopy method, that is, adjust the temperature display area and temperature differences, the temperature distribution with the maximum contrast The color or light is dark.

4 test

4.1 test content a) Inspection of quality defects of facades of buildings; b) Leakage detection of buildings;
