A point cloud is a set of data points in 3D space. The points together represent a 3D shape or object. Each point in the data set is represented by an x, y, and z geometric coordinate. Point clouds provide a means of assembling a large number of single spatial measurements into a dataset that can be represented as a describable object.
The average number of points in the cloud fluctuates between ten to hundreds of millions. Cloud density (average distance between adjacent points) can be anywhere from ten of centimeters to fractions of a millimeter.
Our projects
Based on the tasks set, as well as the characteristics of the object and the required data accuracy, the required 3D scanning method is selected or a combination of them is used to achieve the most effective result.
There are three main types of 3D laser scan survey:Terrestrial laser scanning (TLS) is the most common type of 3D scanning. This method of scanning is carried out when accurate and detailed information is required about the object for the following purposes:
A point cloud, as an array of data, allows you to collect the following information about an object:
The results of processing a geometric data set can be presented in both 2D and 3D formats.
First of all, 3D scanning specialist is setting up the laser and setting the shooting parameters. At this stage, the required density of cloud points, the color of the 3D scan and its quality are established and all ready for scanning (with different duration of data collection, different accuracy of the coordinates of the points can be obtained).
A terrestrial laser scanner is survey equipment with a set step which allows measuring the distance to points, rotating along the vertical and horizontal axes. Up to ten thousand measurements can be made in one rotation, and it also let 3D laser specialist to calculate the angular distance through which the coordinates are taken.
To carry out 3D scan of building, a map of the scanner's station locations is drawn up. The result of building scanning from one scanner location is a complex of data for the particular part of the object or area, presented in the form of a cloud points using a certain density and other parameters.
After carrying out 3D laser scanning, the obtained data can be combined into a single point cloud and, thus, an integral digital 3D image of the object can be obtained.
ROSEСO uses equipment with the appropriate accuracy characteristics depending on the required tolerances and conditions of scanning:
Heavy and long-range 3D laser scanner for buildings. Allows specialist to collect data from the distance of up to 300 meters. This type of equipment is used for filming the facades of buildings and the surrounding areas. TOPCON GLS2000 is capable of collecting large amounts of data - up to hundreds of millions of points from one scanner position.
ROSEСO performs a full range of 3D scanning buildings and structures. To carry out this type of examination, our company has all the necessary specialists. Quality control of work is carried out at all stages of scanning buildings, data processing and design.
Depending on the requirements of the client, ROSECO can implement a BIM model or a complex project development. Currently ROSEСO is the leading company in 3D modelling in Russia according to Autodesk.
In 2020, ROSEСO was included in the list of finalists for the international AEC Excellence Awards with a unique project for the reconstruction of engineering systems at the Trinity-Sergius Lavra in Sergiev Posad (UNESCO World Heritage Site).
