This is the dream of every ruined castle visitor. To be able to see, how it probably looked before. We are delivering this feeling by using the technology of augmented reality (AR). Project: Digital reconstruction of the past look of Reviste Castle located in Slovakia. Imagine stepping into the past through the digital reconstruction of Reviste Castle, a remarkable site in Slovakia. Now, every individual exploring the castle's ruins can travel back in time using their smartphones. This captivating innovation allows visitors to visually immerse themselves in the castle's bygone charm and intimately connect with its rich history. If you need to bring your ruins back to life, get in contact with us. --------------------------------------------------- Follow us for more from our work Overhead4D #3d #augmentedreality #culturalheritage #castles #technology #museums  

🎄 What a Christmas Present! 🎄 We’re thrilled to announce that the Overhead4D team will be joining CIPA Heritage Documentation Emerging Professionals as a Sustaining Member in 2025! Building on our existing partnerships with International Council on Monuments and Sites (ICOMOS) and International Council of Museums (ICOM), we are excited to expand our support to include CIPA, an organization we deeply admire for its dedication to advancing cultural heritage documentation and preservation worldwide. As Sustaining Members, we are committed to contributing our expertise, resources, and passion for transforming the real world into enduring digital assets. This commitment reflects not only our alignment with CIPA’s mission but also our dedication to preserving cultural heritage for future generations. To demonstrate our long-term dedication, we pledge to maintain this membership for a minimum of four years. We are eager to collaborate with the CIPA community, share knowledge, and contribute meaningfully to its goals. At the same time, we look forward to learning from the collective expertise and building valuable connections within this network. Starting in 2025, we will proudly identify as a “Sustaining Member of CIPA – Heritage Documentation.” Our Activities Aligned with CIPA’s Mission: - Cultural Heritage Preservation - High-Fidelity Imaging and Mapping - Accessible Heritage Experiences - Innovation in Digital Solutions - Education and Research And on top of this, we are supporting this exciting news by unveiling our new visual identity (starting with the new logo) designed by GoBigname. #photogrammetry #digitization #culturalheritage #unesco

RADIANCE FIELDS EXPORT from #RealityCapture ??? What an update 👏 👏 👏 RealityCapture 1.5 is now available with more amazing updates then just above mentioned. If you need any help with RC, feel free to get in touch with us. Our team is always happy to help. #authorizedservicepartner Capturing Reality Epic Games #photogrammetry #radiancefields

Reality Capture Network conference, #Rcon2024, was again an amazing experience full of insightful discussions, presentations and great networking. Tomas Barnas and Michal Gula were presenting some insights about the newest technologies used within the reality capturing industry "How to Use 3D Gaussian Splatting in your Next Project" Tomas was participation also on a panel discussion alongside Ellis Malmgren, Ken Flannigan, Sean Young Erik Peterson Michael Rubloff, Russell White, and Robert Killenberger focused on the topic of "Harnessing data overload" Arash Keissami introduced the newest update on his Nira.app and that's the possibility to view the point cloud data. Arash showcased it (thankfully :D ) also on our dataset. Thank you Matthew Byrd, Becca Ralphs and the entire RCN team for organizing such a great event. #dell #nvidia Capturing Reality #photogrammetry #gaussiansplatting

How to use Gaussian Splatting with your next project. Tomas Barnas and Michal Gula will share our experience within this topic on #RCON conference by Reality Capture Network in Boise, ID USA Are you attending R-Con? #laserscanning #photogrammetry #GaussianSplatting Matthew Byrd Becca Ralphs

Measure and Inspect a High-Poly Mesh on Nira.app Create callouts for annotations or defects, measure edges, heights, and complex walls, and calculate areas and perimeters directly in your web browser. A geo-located, cropped, and optimized model (35M with 12x 8K textures) of this small Gothic church in Ochtiná was fully recreated in RealityCapture using 1524 terrestrial and 1071 aerial photos. The model was then uploaded to NIRA.app, which facilitates the showcasing and sharing of high-poly meshes with ease. 💡 Mark specific parts of your model or defects for yourself or your team using a straightforward and intuitive tool. Alternatively, switch to edit mode to create points for more advanced measurements. Capturing Reality Epic Games #photogrammetry #culturalheritage

🦌 From paper through pixel to a 3D print: This huge paper-crafted deer landed in our Overhead4D office with a request: "Can you make an accurate 1:1 digital copy of it?" Armed with a SONY camera, we took pictures from all possible angles and imported them into #realitycapture. 💡Tip 1: Consider all the small fragments of deer antlers as separate objects. Capture all the necessary images of the deer from all angles, treating it as a single object. Then, focus on smaller pieces, capturing each antler separately. 💡Tip 2: If you didn´t use a laser scanner and you need a proper scale, you can input the measurements of selected edges in the "IMAGE 2D tools" menu under "Define Distance." Alternatively, you can use targets generated by RC itself and place them in the scene before capturing. Capturing Reality Epic Games #3Dprinting #photogrammetry

𝗧𝗵𝗲 𝗳𝗼𝗿𝘁𝗶𝗳𝗶𝗲𝗱 𝗘𝗮𝗿𝗹𝘆 𝗚𝗼𝘁𝗵𝗶𝗰 𝗰𝗵𝘂𝗿𝗰𝗵 𝗶𝗻 𝗞𝗿𝗮𝘀𝗸𝗼𝘃𝗼, 𝗦𝗹𝗼𝘃𝗮𝗸𝗶𝗮, is an ideal subject for digital reconstruction using photogrammetry. Why? - The church is located on the outskirts of a small village, far from other buildings and people. - The church and bell tower are separate from each other and not surrounded by trees or vegetation, making them easy to photograph from all angles and heights. - The old structures of the walls are perfect for photogrammetry reconstruction, so a laser scanner was not needed to create a highly detailed and accurate 3D model. The project includes 1,233 ground pictures and 1,260 aerial pictures.

Despite these challenges, we captured 4900 photos of the church and its surroundings. 𝗧𝗶𝗽 𝟭: 𝗙𝗼𝗰𝘂𝘀 𝗼𝗻 𝘄𝗲𝗮𝗸 𝘀𝗽𝗼𝘁𝘀 Pay attention to weak spots not visible from the air, like trees touching the facade. Help the alignment process by capturing close-up photos of these spots. Also, take mid-range and long-range photos to provide context and ensure good alignment in #RealityCapture.

This ensures a seamless connection between aerial and ground photos for easy drag-and-drop alignment. Capturing Reality Epic Games #photogrammetry #drone #culturalheritage #digitization
