Abstract

Abstract

For the ultra-long and complex isolation structures, the isolation supports engendered a large lateral displacement phenomenon easily during construction stages. Real-time and accurate deformation monitoring for isolation supports is an effective basis for guiding construction in progress and judging actual stress of structures. The traditional measurement method of contact displacement is restricted by dimensions, accuracy, complicated operation, and installation, etc. The use of the non-contact measurement method based on computer vision can effectively overcome shortcomings of the traditional method. A displacement monitoring system based on computer vision was proposed. Network cameras were used as acquisition devices, and the color matching technique was used to realize displacement measurement of targets. The system was applied in a large terminal building in the west of China, and used for displacement monitoring of isolation supports in the building, and the monitoring data of deformation and temperature of isolation supports were analyzed. The results showed that the monitoring system based on computer vision could accurately measure deformation of isolation supports, and serve as an automatic and economical intelligent system for the structure for a long time. The deformation law changed with temperature for isolation supports of the ultra-long isolation structure was given.
