In this series of short articles, we will try to explain very basics of engineering workflow that include point clouds, at any point. We are aware, that most people have some knowledge of the topic, but the ultimate goal of this series is to inform our current or potential partners, how we create our products and how to use them efficiently without huge experience.
WHAT IS A POINT CLOUD ?
Technically point cloud is a data base containing points in three-dimensional coordinate system. However from the typical workflow perspective the only important thing is, that point cloud is a very accurate digital record of an object or space. It is saved in form of a very large number of points that cover surfaces of a sensed object.
Points in a point clouds are always located on the external surfaces of visible objects, because this are the spots, where ray of light from the scanner reflected from an objects.
