Abstract

In order to improve the efficiency and accuracy of volume measurement of the large coal pile, a set of portable 3D laser scanner is designed. This device uses the 2D laser scanner as the measurement module supplemented by the high-accuracy sensor, to scan the 3D morphology surrounding the coal pile. Based on characteristics of the scanner and structural features of the coal pile, the data preprocessing arithmetic is optimized, which synchronously completes the scanning point noise reduction during the measurement process and saves the time required for the 3D modeling. Spatial interpolation is adopted to reconstruct the 3D model, which fills in the cavity at the coal pile top, filters excessive scanning points at the bottom, and improves the efficiency of the 3D modeling and volume calculation. As shown by the experiments, only a few minutes are required to complete the 3D morphology measurement of the coal pile, and it will generate the 3D model and volume within 20 s after the measurement.
