Point cloud – Wikipedia
Point clouds are generally produced by 3D scanners or by photogrammetry software, which measure many points on the external surfaces of objects around them.

What Is a Point Cloud and How Is It Used? – FlyGuys
Point clouds are generally created in one of two ways, LiDAR and photogrammetry, and are georeferenced for accuracy. LiDAR Light Detection and Ranging, or LiDAR, is a remote sensing method that scans an area with a laser and then measures the light’s reflection and range from the earth’s surface.

A point cloud is generated by scanning a series of locations, with overlap, ensuring all angles of a mapped area are covered. During the post-processing stage, the individual datasets merge to create one accurate point cloud. Mobile mapping Mobile mapping achieves a similar result, albeit less accurate.

Point Cloud Modeling 101: Everything You Need to Know – TOPS
The answer is typically a laser scanner. Site surveyors can create 3D models from point clouds by using LIDAR lasers. With the laser, you scan a chosen environment — such as a construction site — and the scanner records data points from the surfaces within it.

Photogrammetry This is more a methodology than a specific type of tool. To generate a point cloud with photogrammetry, you would cameras to capture the space from all angles and then process those images with specialized software to reconstruct the space in 3D.

What Are Point Clouds, And How Are They Used? – dronegenuity
Point clouds are essentially the simplest form of 3D models. They are collections of individual points plotted in 3D space. Point clouds are created by performing a scan of an object or structure. Scans are completed by using either a laser scanner or through a. Laser scanners work by sending out pulses of light to the surface of an object and …

What are point clouds? 5 easy facts that explain point clouds – Vercator
Point clouds are most commonly generated using 3D laser scanners and LiDAR (light detection and ranging) technology and techniques. Here, each point represents a single laser scan measurement. These scans are then stitched together, creating a complete capture of a scene, using a process called ‘registration’.

What are point clouds | Correvate – Vercator
By Charlie Cropp MRICS August 18, 2021 Point clouds are a powerful way to represent a whole object, scene or structure. When colour information is added, the point cloud becomes even more powerful, presenting data collected in 4D. They aren’t new and have been around since the 1960s. lesoutrali bot
