Reality Capture in engineering<\/strong> is the set of methods used to digitally record the physical condition of an environment, asset, or infrastructure through technologies such as 3D laser scanning, LiDAR, photogrammetry, imagery, drones, and other sensors. The result may take the form of point clouds, meshes, orthophotos, 3D models, maps, georeferenced images, or integrated datasets that support surveying, design, verification, As-Built, BIM, Digital Twin, and asset management.<\/p>\n\n\n\n

The concept is broader than any specific technology. LiDAR measures distances using light pulses; photogrammetry reconstructs geometry from overlapping images; terrestrial laser scanning records millions of points from controlled positions; drones can carry cameras or LiDAR sensors. Reality Capture integrates these sources to transform physical conditions into digital information usable by engineering.<\/p>\n\n\n\n

It should also not be confused with Scan to BIM. Scan to BIM is a subsequent process in which captured data \u2014 typically point clouds \u2014 are interpreted and converted into BIM objects or models. Reality Capture covers acquisition, registration, processing, georeferencing, classification, validation, and data preparation before the data are used in design or modeling.<\/p>\n\n\n\n

Artificial intelligence adds another layer. Computer vision and machine learning models can classify points, recognize objects, segment surfaces, detect changes, and support information extraction. Value emerges when automation reduces processing effort without losing accuracy, traceability, or connection to the original survey.<\/p>\n\n\n\n\n

What makes up a Reality Capture process<\/h2>\n\n\n\n

The process begins before the equipment is selected. The team needs to define what must be captured, what accuracy is required, what product will be delivered, and how the data will be validated.<\/p>\n\n\n\n

A survey intended for a preliminary study has different requirements from a contractual As-Built or a fabrication basis.<\/p>\n\n\n\n

The most common technologies include:<\/p>\n\n\n\n
