What is Point cloud

1.

Points at a virtual space resulting from scans that represent an object surface but only reconstructing the location of benchmarks or targets. Learn more in: 3D Scanning and Simulation of a Hybrid Refrigerator Using Photovoltaic Energy

2.

A set of three-dimensional distributed points which result from a laser or photogrammetry scan. Each point cloud is calculated by matching several photographs (in the case of photogrammetry survey) so as it corresponds to a point of the surface of the surveyed object. The density of a point cloud is dependent on the quantity and quality of the photos taken, but also on the followed protocol of the shooting.

3.

A set of data points in space, generally produced by 3D scanners and used to represent 3D objects in visualization, animation, rendering and 3D manufacturing applications ( https://en.wikipedia.org/wiki/Point_cloud ). Learn more in: Humans Enter the Age of Avatarism

4.

Dataset composed by points located in a three-dimensional coordinate system derived from both a range and an image based geometrical survey.

5.

Created by 3D scanners; is a set of data points in three-dimensional coordinate system which define by X, Y, and Z coordinates. Learn more in: The Advantages of Using Laser Scanners in Surveying in Protected Sites: A Case Study in Historical Peninsula in Istanbul

6.

Set of points that define a three-dimensional model of an object. Each of these points is identified by its position in space and its colour characteristics. Learn more in: “Discretizzazione” and Data Analysis at the Time of “Total Survey”

8.

Set of vertices or points in a three-dimensional coordinate system. These vertices are usually positioned in 3D space and have a set of coordinates (x, y, z). These sets of points normally are representative of the external surface of an object. Learn more in: Virtual Reality and Point-Based Rendering in Architecture and Heritage

16.

A point cloud is a set of data points in some coordinate system. In a three-dimensional coordinate system, these points are usually defined by X, Y, and Z coordinates, and often are intended to represent the external surface of an object. Point clouds may be created by 3D scanners or multi-image processing based on digital photogrammetric shooting.
