    • PURPOSE: A real-time three-dimensional image measurement monitoring system using an infrared light thermal image camera for a structure is provided to photograph markers in the daytime and at night time, thereby monitoring a structure on a real time basis. CONSTITUTION: A real-time three-dimensional image measurement monitoring system using an infrared thermal imaging camera (120) for a structure (1) includes markers (110), an image processing unit (130), a wireless transmission unit (140), a wireless reception unit (150), a parallel arithmetic unit (160), and a displacement measuring unit (170). The markers are installed at several points respectively and generate heat hotter than ambient temperature. The infrared thermal imaging camera is fixed on a fixture such as the ground surface separately with the structure and photographs the markers or a plurality of the infrared thermal imaging cameras is installed on the structure. One of the infrared thermal imaging camera photographs a reference marker installed on a correction reference structure fixed on the ground surface, and the rest photographs the markers. The image processing unit synchronizes thermal image signals of the markers photographed by the infrared thermal imaging camera and compresses the synchronized signals by digitalizing. The parallel arithmetic unit paratactically tracks coordinates of the each marker based on the thermal image signals of the markers processed by the wireless reception unit, thereby obtaining two-dimensional coordinates.
