Abstract
Calculating surface area is quite common in daily life; however, due to the irregular shapes of objects, traditional feature point data collection methods are not suitable for complex surfaces. Therefore, this study employs 3D laser scanning technology, using the Ligrip H120 handheld rotating laser scanner for data collection of the artificial stone. Based on four algorithms, we performed 3D reconstruction of the obtained point cloud data. Subsequently, we developed a program for surface area calculation using the Python interface of CloudCompare software and the Open3D library. The results indicate that the surface area measured with this technology has an accuracy improvement of 1.03 percentage points compared to the traditional sticker method, while the time required was reduced by three-quarters. This technology demonstrates high precision, strong reliability, and high efficiency in calculating the surface area of irregularly shaped objects.
