Research on the Application of Handheld SLAM Equipment in Earthwork Measurement
With the continuous innovation of surveying and mapping technology,traditional data collection meth-ods have also encountered related drawbacks in the use process and cannot meet the time and accuracy require-ments of existing projects.The emergence of three-dimensional laser scanning technology has greatly improved the quality and collection speed of data,which provides data support for the development of existing projects.This ar-ticle studies the application and advantages of handheld SLAM technology in earthwork survey,analyzes the prin-ciples,algorithms and key technologies of handheld SLAM technology,and uses handheld SLAM and 3D laser scan-ners to verify the accuracy of earthwork in combination with engineering examples.Experiments have shown that handheld SLAM technology can achieve high-precision and efficient data collection and modeling in earthwork measurement,which lays a data foundation for earthwork volume calculation.
