Application of Smart 3-D Laser Scanner in Structural Health Monitoring

摘要：

As one of Full Field Optical Measurement(FFOM)technologies,Smart 3-D Laser Scanner measurement technique enables to monitor the shape and dimension measured-objects in non-contact,remotely and globally.By taking its capability in capturing 3-D spatial information,3-D Laser Scanner has been utilized effectively in numerous field application,such as,landscaping simulation during structural design stage,bridge load test,and maintenance purposes.In this paper,the monitoring technique is reviewed and verified.The modal response from dynamic structural analyses of field-monitored structures is studied.Through field-application experiences,it is confirmed that 3-D Laser Scanner is an easy-handled device to capture spatial information of shape-complicated structures.Moreover,it can be integrated with generic structural health monitoring system to assess the updated structural performance of existing structures’ performance in a long term structural health monitoring scheme.
