This paper describes a study of high accuracy and low cost position measurement system using laser range finder (LRF), and its appliction for construction foundation. In proposed system, the data obtained from LRF assuming the arc-shaped contours of the object, the center position was analyzed introducing the least square method and maximum likelihood estimation. The error bertween the analysis and the measurement was corresponds enough to the allowable accurate range. Applying this system to the construction work, the high accurate pile marking and the pile drive positioning were recognized. Since the position and direction of the worker was easily found, the high effcient and short term works were surely performed.This paper describes a study of high accuracy and low cost position measurement system using laser range finder (LRF), and its appliction for construction foundation.
