A 3D laser scanner is a device that captures the shape and surface information of an object in three dimensions using laser technology. The scanner emits a laser beam that sweeps across the surface of the object and measures the time it takes for the laser to bounce back to the scanner. This information is collected by a sensor in the scanner and used to create a point cloud of measurements that represents the surface of the object. 3D laser scanners are capable of capturing objects of different sizes and shapes with a high level of detail and accuracy.
