Abstract
Laser scanning (3D Imaging) systems have been widely adopted in construction and infrastructure management domains. One challenge of using such systems in the field (e.g., construction quality control or bridge inspection) is to efficiently and effectively configure sensors to conditions and requirements, ensuring data have been collected with satisfying qualities. Engineers need to understand how sensors work, check domain requirements and site conditions; then determine sensor locations and configurations based on knowledge and experience. Performance of such configurations rely the experience, knowledge and skill level of the engineers using the scanners.
This thesis synthesizes AEC domain requirements to develop models for formally representing these requirements, investigates specifications of multiple scanners to develop, and generic analytical sensor models of terrestrial laser scanners. Based on these and sensor models, the author developed a mathematical model for quantifying impacts of various scanning parameters on the qualities of the data using several cases with conditions and domain requirements, comparing the qualities of that data against that of manually collected data. Results show this model can help engineers conduct cost-benefit analysis to support data collection strategy determination, and potentially ensuring important information is collected within the constraints of sensor capabilities, time, space, and budget.
