3D #Visualization requires a real strategy to setup new projects involving multiple camera angles with product #configurations. To keep organized we group scene objects, lights, and cameras. Scenes in #Maya are optimized and made visible allowing for focused editing and efficient use of resources.

Imaging flying objects requires skill and sophistication. I have great admiration for cameramen creating footage of birds and insects for wildlife films. As a photographer, I specialise in capturing birds in flight and I have several images of the sky to prove it! However, imaging faster projectiles requires a more sophisticated device. That's why IDT has entered into an agreement with MS Instruments to market the Mini Flight Follower. The device enables the imaging of ballistic projectiles for up to 100 metres, making it perfect for studying rifling, sabot separation, pitch & yaw, and more. The Mini Flight Follower is a great addition to the range of high-speed imaging equipment supplied by IDT. I can't wait to spend more time with it in 2024! Check out the link to learn more about the Flight Follower: https://lnkd.in/eTrVnuHb (Note – The banner image was taken using a Flight Follower, but from an older camera, hence the poor image quality in comparison to todays cameras. Access to recent images are understandably rarely available for public use)

It's been a challenge, but I'm really happy with how this digital twin side project has turned out. Generated from photographs taken with a regular DSLR camera, this model was built using Reality Capture 1.3 and was then simplified to 4 million triangles. Photogrammetry of shiny objects can be tricky, requiring you to come up with ways to mute any reflections. In this case, a combination of bouncing and diffusing the light along with a narrow apeture and slow shutter speed, did the trick. Similar problems occur in large scale digital twins of properties when using photographs captured by drone. Reflective surfaces such as window glass will often cause all sorts of aberations in the resulting model. You can check out the full 3D model in Sketchfab using the following link: https://skfb.ly/oOKoo I'm more than happy to answer any questions or share my process. Just ping me a message! #photogrammetry #digitaltwin #realitycapture

One of the key ingredients for beautiful images is light, or the absence of it. Particularly in drone video and photo work there’s usually not much manipulation you can do using artificial lights, so working with the sun is essential. I love going out early to catch those first rays of light that create shadows and highlights. . . #dronepilot

I did a 3d scan recently of Eternal Springtime by Auguste Rodin at the art institute in Chicago. I used NeRF reconstruction with Luma and the results are pretty great I think. The model is available on my Sketchfab, go check it out! The process of NeRF scanning has some drawbacks like lower mesh resolution and where it fills in the blanks where you might want 100% accuracy. So for accuracy and detail I believe photogrametry and LiDAR is still the best. Currently, I think for quickly producing reasonably detailed, complete meshes and scenes even from a limited amount of photos and video, it is a very good tool. It’s ability to scan scenes is pretty amazing as well. It will be interesting to watch these tools develope further and become more accurate. https://lnkd.in/gjx2w42M #art #sculpture #3dscan

Check out this stunning 3D realistic scene model that we created using #Get3DMapper, a tool we developed. The model was generated from images captured from both drone and ground view. We then used UE to render and visualize the mesh data, resulting in an impressive video that allows us to change the lighting in the scene. We're thrilled with the results and can't wait to see what else we can create with this technology. #3DModeling #Visualization #DroneImagery www.get3d.ai

The growth of the drone market and evolution of drone tech have led to an increase of aerial photography for incident sites, helping produce high resolution imagery of roadway evidence like tire marks, gouge marks, debris fields, and vehicle rest positions. Accurately mapping evidence is a key process in creating a scaled crash-scene diagram, and image rectification serves as a quick and straightforward method for producing these diagrams. In this study, previously published by SAE International, we evaluate the precision of the photo rectification process under diverse roadway geometry conditions and varying camera incidence angles.

Great post. In #photogrametey, quality photos are just as important as ground control. Great explanation of why photos can come out blurry and what to do about it (shutter speed, slow down, fly higher).
