Processing of High Frequency Local Area Laser Scans for Construction Site Resource Management

Rapid local area modeling, with the assistance of high frequency laser scans, is a valuable tool for construction site resource management applications. However, as a central component of the modeling process, the rapid processing of tens of thousands of scanning points in a fraction of seconds is still a challenging task that requires further investigation. This paper describes a study aimed to investigate the performance of various data processing algorithms for range points that were captured from laser scanners in both indoor and outdoor environments. An integrated range data processing module was developed in this study, allowing for quickly experimenting with various combinations of data filtering, transformation, and segmentation approaches. The identified group of processing algorithms could robustly handle sensor noise and accurately process high frequency local area laser scans.
