3D mapping of buildings and territories: laser scanning for precise measurements<\/h1>\n
Briefly:<\/strong> 3D mapping is the creation of an exact digital copy of an object using a laser scanner and a depth camera. The measurement error in the finished model is kept within 1\u20132 cm at a distance of up to 10 meters, which covers 90% of the tasks of reconstruction, design and area accounting.<\/div>\n

The guide will be useful to designers, architects, restorers, commercial property managers and anyone who needs accurate measurements without a week-long visit by a measurer with a tape measure. Let's take a step-by-step look at how we shoot objects in 360\u00b0 Space - from preparing the site to issuing a point cloud and a walk-through tour. We\u2019ll show you where 3D mapping really saves money, and where it\u2019s better to choose a classic tacheometer.<\/p>\n

Step 1. Define the task and select equipment<\/h2>\n

The first thing we ask the client is: what will you do with the model? Measurements for redevelopment, linking engineering systems, inventory, restoration project - each task has its own set of equipment and its own shooting density.<\/p>\n

For interiors up to 3000 m\u00b2, we most often take Matterport Pro3 - it is a combination of lidar and panoramic camera. It provides a ready-made point cloud with an accuracy of about \u00b11 cm and at the same time a virtual tour, which the customer walks through in a browser. For facades, industrial sites and territories, we connect stationary scanners such as Leica BLK360 or FARO - we are already talking about millimeter accuracy and distances of up to 60 meters. A client from Kazan ordered mapping of a 4200 m\u00b2 workshop with metal structures - they took a combination of Pro3 and BLK360, because they needed both precise beams for a crane beam and a tour for contractors.<\/p>\n

Step 2. Prepare the subject for shooting<\/h2>\n

Preparation is half the battle. The laser sees everything: a bucket of water in the middle of the corridor, a stepladder, cables on the floor. All this will end up in the model and then you will have to clean it by hand.<\/p>\n

The day before departure, we send the client a checklist: open all doors, turn on the lights in all rooms, remove people and animals from the frame, close the mirrors (otherwise the scanner will get confused by reflections), check that there is no active construction work with dust. We mark glass partitions with masking tape - otherwise the lidar does not see them and \u201cstitches\u201d two rooms into one. When shooting a 600 m\u00b2 restaurant in Moscow, we were asked to shoot at night, after closing - so we did, scanning took 4 hours instead of the expected six during the day with visitors.<\/p>\n

Step 3. Scan<\/h2>\n

A shooting point is placed every 2\u20132.5 meters in the interior and every 5\u20138 meters in the open area. One point is taken for 20\u201340 seconds - the scanner makes a 360\u00b0 panorama and simultaneously measures the distance to all surfaces around.<\/p>\n

The average apartment of 80 m\u00b2 is 25\u201330 points, work for 1.5 hours. Two-story house 300 m\u00b2 - 90\u2013120 points, 4\u20135 hours. An industrial building of 5000 m\u00b2 is already a full day of filming with an assistant. We always shoot with a reserve: an extra 10\u201315 points in narrow places and on stairs saves us from \u201choles\u201d in the cloud, which then cannot be sealed with anything.<\/p>\n

Step 4. Process the data and assemble the model<\/h2>\n

After shooting, the data goes into cloud processing - stitching point clouds, constructing a polygonal mesh, generating a floor plan with automatic dimensions. For Matterport this takes 4-24 hours depending on the size of the property. For stationary scanners, processing is manual, longer - up to 3-5 working days.<\/p>\n

At the output, the client receives: a point cloud in E57, XYZ, PTS formats for loading into Revit, ArchiCAD, AutoCAD; floor plan in PDF and DWG with dimensions; and the virtual tour itself with a ruler tool - the customer himself can measure any distance directly in the browser.<\/p>\n \n \n\n \n \n \n \n \n \n
