This part of the process requires the most time and the more accurate the sparse cloud and mesh, the more accurate the final model will be. The gif above shows the complete dataset for the first angle another dataset was captured with the apple on its side.

Because I’m using a manual turntable, I tried to get the rotation as even as possible by hand. Lighting – Avoid the Shine and Reflectionįor taking the photos, an automated turntable will give the most consistent rotations and evenly lit photos.

You can see the result of this setup in the screen of the camera the apple is brightly lit and stands out from the background. I placed the turntable onto a piece of black foamcore as a bottom surface, and another piece as a background. I used a wooden turntable for my base and cut a piece of black foamcore to fit as a cover. As an amateur photographer, I wanted to try and recreate as much of the effect as I could while using the equipment I already had.

I was inspired by Erik Christensen’s video ‘ Scanning into the Void’, which covers many of the basic fundamentals of creating a turntable photogrammetry setup.

In our simple benchmark between CPU and GPU, we demonstrated the huge gains Paperspace's infrastructure can provide to GPU accelerated photogrammetry in Photoscan. Photoscan's GPU Acceleration is a powerful feature that can make use of Paperspace's NVIDIA GPU infrastructure. This model would take an estimated 1.75 hours to complete processing. Note: Make sure CPU is also enabled in the GPU tab. This model would take an estimated 32 hours to complete processing. Note: In order to test the CPU - GPU should be disabled. In the Menu Bar, click Workflow > Build Dense Cloud We used the benchmark file provided by Agisoft in order to build a dense cloud model on Ultra High settings. We've put together some helpful benchmarks to between CPU and GPU on Paperspace's P5000. In the GPU section, select or unselect the GPU device.The use of the GPU can be enabled or disabled in the Processing Options: So how we do enable this in Paperspace? 2.

As a rule of thumb, projects with high overlap, high image content and thus with a high number of keypoints benefit more from the speedup. This speed increase depends highly on the project, the number of images, the image size, and the image content. With their GPU Acceleration feature, what would normally take close to days to process can now be done in a couple of hours.
