FIELD: measurement equipment.
SUBSTANCE: invention may be used to assess reliability of complex spatial structures from polymer composite materials (PCM) based on thermal control results during loading of items by static or dynamic load. The method includes registration of a spatial thermogram of the control object and its processing for defect detection. Simultaneously with registration of the spatial thermogram they perform registration of a video image of the control object for clarification of its location. Devices of thermogram registration and video image registration are located in front of the control object with the possibility to match fields of view of the control object. The video image of the control object is registered in the same spatial coordinates as the thermogram. The matrix of the combined thermogram is built, and its elements are processed to produce information on the object condition. The system includes a device for registration of thermograms, a device of video image registration, a unit of visualisation and processing of thermograms, a switch, a signal counter, a signal inverter, the first and second summators, a threshold device and a unit of signal matrix formation.
EFFECT: improved validity of detection of local areas of lower strength, increased validity of results of assessment of technical and operational condition of complex structures and their elements from PCM.
