| Abstract: | The use of point clouds acquired by different techniques and tools such as laser scanners, LIDAR or photogrammetry (terrestrial and aerial) is increasingly being used in the construction and building environment. A point cloud is nothing more than a collection of points defined by their coordinates within a Cartesian space: X, Y, Z. In turn, each point can have an additional registered property: colour, intensity of the returned pulse, etc. The points within these clouds are unstructured and contain no semantic, geometric or topological information about the objects. This lack of structure forms a bottleneck in the processing of this data and in developing and obtaining useful information derived from it. In order to evaluate the performance and possibilities of multispectral voxels, a series of data has been collected with different sensors producing multiple point clouds. This data collection was focused on the study of an enclosure wall of a historical heritage building. Once the point clouds have been acquired from each sensor, voxelisation has been performed, fusing the multispectral information in each voxel. By means of statistical measurements, we can ensure the quality of the fusion process. |
