𝐔𝐧𝐝𝐞𝐫𝐬𝐭𝐚𝐧𝐝𝐢𝐧𝐠 𝐀𝐜𝐜𝐮𝐫𝐚𝐜𝐲 𝐢𝐧 𝐃𝐫𝐨𝐧𝐞 𝐌𝐚𝐩𝐩𝐢𝐧𝐠: 𝐑𝐞𝐥𝐚𝐭𝐢𝐯𝐞 𝐯𝐬. 𝐀𝐛𝐬𝐨𝐥𝐮𝐭𝐞 Ever wondered how precise drone-captured data really is? There are two key accuracy levels to consider: relative and absolute. Let's break it down: ➡️ 𝑹𝒆𝒍𝒂𝒕𝒊𝒗𝒆 𝑨𝒄𝒄𝒖𝒓𝒂𝒄𝒚: Focuses on relationships within the map/image, like a detailed floor plan. Furniture placement is accurate relative to each other, but not necessarily to the real world. ➡️ 𝑨𝒃𝒔𝒐𝒍𝒖𝒕𝒆 𝑨𝒄𝒄𝒖𝒓𝒂𝒄𝒚: Ensures the map/image precisely reflects real-world locations, like perfectly matching furniture placement on the map to its exact GPS coordinates. 𝑪𝒉𝒐𝒐𝒔𝒊𝒏𝒈 𝒕𝒉𝒆 𝑹𝒊𝒈𝒉𝒕 𝑨𝒄𝒄𝒖𝒓𝒂𝒄𝒚: Relative Accuracy (2-3m x/y, 6-9m z): Ideal for small-scale projects needing approximate measurements or frequent data updates, such as: ✔ Volume estimations ✔ Progress tracking ✔ Inspection planning Absolute Accuracy (centimeter-level): Perfect for high-end projects requiring precise, geo-referenced data. This involves using survey control points and advanced processing (RTK/PPK). This is crucial for: ✔ Construction planning ✔ Boundary surveys ✔ Topographic mapping Want to learn more?

Had a fun this past weekend in northern Italy doing a quick down-and-dirty LiDAR scan for an architectural design and permaculture project of a callabente in the Alps. This scan was made with my iPhone in ~10minutes just to have digital measurements to reconstruct some rudementary floor plans - as the archives have some wonderfully vague details of the structure and we wanted to have a secondary input to hand measuring by laser. We will be returning in the spring for a week or so and will make a much more comprehensive set of scans both by hand-held and drone surveying. Super excited to do a bit of a dive to compare #LiDAR, #Photogrammetry, and #GaussianSplats for digital reconstruction. Additionally, I'm quite excited about some #OpenSource software i've found for direct GS-to-mesh workflows that provide some super detailed outputs. Ideally, these methods will offer a quick method for GS-to-subd surfaces for editing - particularly for planning earthworks, terracing, and other landscape arch/regenerative agricultural elements to the surrounding 3 acre property. But on a purely aesthetic level, and since this is also a #regenerative ag meets architecture project, I just love how adding clipping planes on a scan like this enable a ct scan like effect for a building... conceptually it really helps blend the space between what is coined 'structural biology' and what is conventionally thought of as architecture. #architecture #landscapearchitecture #permaculture #rhino3d #surveying

The SCATTER Project: 3D modelling ancient oaks Join us this Wednesday for our webinar with Dr Cecilia Chavana-Bryant who will present her current research on characterising and comparing tree architecture across the UK's ancient oaks, creating an open-source, 3D digital archive with these living legends. The SCATTER project has spent the last year making detailed 3D models of some of the UK’s most famous old oak trees. Ancient tree architecture is often very complex making it hard for scientists to determine how much carbon they have sequestered, and which conservation measures are most effective. During the project they visited 40 ancient and veteran oaks and made 3D models of each tree using a laser-scanning technique known as LiDAR.

🌍 Explore one of the remarkable projects by the Navigation Geodetic Center!🌍 We proudly present a 3D model of the Palace of Labor in Kharkiv, one of the largest and most iconic neoclassical buildings in the city’s central area. 🏛️ Originally built in 1916 by architect Ipolyt Oleksandrovych Pretro, this six-store building with three inner courtyards housed a profitable insurance company and luxurious apartments - each featuring no fewer than six rooms, designed with the latest technologies of the time. Only the wealthiest citizens could afford to live here. 💼💎 Tragically, this historical gem was destroyed on March 2, 2022, during a missile strike. Our goal in creating this 3D model is to document the destruction caused by the attack and preserve the memory of this architectural treasure. To gather the data, we employed cutting-edge technologies including #TotalStationSyrveing, #GNSS, #Photogrammetry (using drones), and #LaserScanning with two world-class Leica Geosystems part of Hexagon scanners - the #Leica #RTC360 and Leica #ScanStationP30. 📐📸 🔗 Check out the model here: https://lnkd.in/ddXhaUG6

🧠 👉 FARO: Point Clouds for Beginners https://bit.ly/3ToCcrg 👈⚡ With an ever-growing array of Lidar technology readily available, anyone can effortlessly map the environment around them. For newcomers to Lidar, this presents a variety of opportunities but requires the surveyor to understand point clouds. What is it, how is it created, and how is it used? In this article, we'll look at the frequently asked questions about point clouds and get you started with all the information you need. A point cloud is a collection of points of data plotted in 3D space, using a 3D laser scanner. If you're scanning a building, for example, each virtual point would represent a real point on the wall, window, stairway, metalwork, or any surface the laser beam meets. #experienceSynergy #FARO #realityCapture #laserScanning #focus #sphere #safety #survey #construction #architecture #engineering #energy #preservation #facility #management #superior #precision

Muhu Church gets its very own #DigitalTwin! Our, 3Di team recently completed an exciting project: creating a 3D model of the historic Muhu Church in Saaremaa, Estonia, using #photogrammetry. We captured the church's intricate architecture and details, producing a geometrically accurate digital twin, that not only preserves this medieval gem for future generations, but also allows for more efficient building management. How did we achieve this result? 👉 Aerial surveying: We used the DJI M300 drone, to perform precise aerial surveys, documenting even the most inaccessible parts of the church. This was used, to ensure that the roof of the building and higher points, were captured correctly. 👉 Close-range photogrammetry: High-resolution cameras were employed to capture every nook and cranny. This allows for the creation of such high-detailed models, as every angle is captured. From the experience of 3Di, photogrammetry has proven to be INVALUABLE for cultural heritage preservation. Creating these 1:1 scale models significantly enhances building management by providing a detailed and accurate reference of the structure. This digital replica aids in planning and executing future renovations, ensuring historical accuracy and structural integrity are maintained. Additionally, it allows for more efficient maintenance and monitoring, helping to preserve the building's condition over time. But this, does not only apply for historical buildings, no no no no.... This technology can also revolutionize other fields such as architecture, construction, and environmental monitoring, offering new levels of precision and efficiency. Just imagine the possibilities! We think, it is only a matter of time, before photogrammetry becomes an industry standard! So..... Let's connect and discuss how photogrammetry can benefit your projects! 🌍✨ #Photogrammetry #DigitalTwin #Innovation #DJIM300 #CulturalHeritage #3DModeling #FutureTech
