Stockpile Survey is to conduct a 3D measurement to a pile via survey instrument such as total station, laser rangefinder, GPS and 3D laser scanner, and then obtain a three-dimensional model of the pile via data processing for the further volume or surface area calculation.
The traditional measurement method is to use GPS or total station to carry out the survey, which is not only time-consuming but also need walk through the site, bringing safety hazards to the engineer. 3D laser scanning techonology is an advanced measurement method of stockpile in the world. It can obtain a high-resolution 3D point could, quickly generate TIN & DSM for the area and volumn calculation and increase the survey accuracy as well as the work efficiency. SureStar's U-Arm 3D laser scanner is a long distance pulsed laser scanner suitable for scanning large-scale stacks. It has the features such as high-precision and high efficiency, being able to provide a complete solution for a stockpile survey with a professional post-processing software.
