In engineering projects, it is often necessary to accurately measure the surface area and volume of objects. However, irregularly shaped objects, such as green areas on slopes, rockeries, sculptures, and mining voids, cannot be accurately measured using simple formulas. Some complex mathematical calculation methods, such as contour, finite element methods, and grid methods, are limited by the quality and quantity of measurement data, resulting in inaccurate and inconsistent surface area and volume measurements.
The development and application of handheld 3D laser scanners provide a new technical means for rich spatial information about objects. It can quickly and accurately obtain large-area, high-density spatial 3D data and is a non-contact active measurement system with high measurement point accuracy, large density of space points, and fast acquisition speed, overcoming the weaknesses of traditional measurement methods with low point density and efficiency.

The Slam100 handheld laser scanner integrates laser Lidar and industrial-grade Slam algorithms, thus having the ability to quickly obtain complete point cloud data of large and complex scenes. When used with Geomagic Studio software developed by Geomagic, it can create accurate MESH models from point clouds quickly, ensuring users get perfect polygon models that can output various industry-standard format results.
Based on the MESH model, Cloudcompare also has the ability to calculate surface area and volume.
