Digital Image Measurement Technology for High-Rise Structure Torsion Deformation Measuring

Abstract:

In the field of structural health monitoring, digital image measurement as a new monitoring technology is gradually being widely used. Real-time measurement for the torsion, however, has been the difficulty in the high-rise structure monitoring. This paper first analyzes the factors that caused the structure’s torsion and introduced the principle, but also the working mode of this new image measurement system, then a measuring scheme for high-rise structure’s torsion has been proposed, which indicates that this measurement technique is an effective new method.
