| Abstract: |
The current process for acquiring bridge geometric data for the National Bridge Inventory (NBI) is based on manual surveying, manual data processing and interpretation. Hence, it is time-consuming and error-prone. This paper presents a laser-scanning-based approach to acquire geometric data for bridge inspection, describes a case study and discusses the advantages of this approach over current practice from the perspectives of both bridge inspection and management. Both current approach and laser-scanning based approach are composed of three major steps of data collection, data processing and data interpretation. Yet, a comparison of these approaches highlights major differences in the accuracy and comprehensiveness of the data collected. Based on the comparison, we suggest a need for a formalized way to decompose higher level bridge inspection goals to enable successful application of laser scanning technology for bridge inspection. |
