In the case of Zeniarai Benten VR, the first process of calculating the positions of the photos (Align) took about 60 hours (with Core i7-7700HQ and GTX1070). Photogrammetry carries out most of the tasks autonomously. ※You can change the cache location here Recommended Tools Insufficient disk space could cause a problem for the Photogrammetry processing, so please make sure you have enough space when you are working on your photogrammetry project. So, I recommend setting the cache location in the SSD. When processing, the data is saved frequently. So, the processing will progress smoothly with SSD, which has a quicker read/write time. In wide-area Photogrammetry, the project file of 3DF Zephyr could be close to 20GB, depending on the size of the target area. Even if multiple instances of 3DF Zephyr appeared working without problems, they would crash when completing the processing. In particular, launching multiple 3DF Zephyr increases the risk of a crash. Be aware that significant memory shortage could make the PC crash. In the case of wide-area Photogrammetry, 32GB may not be enough, so 64GB would be a safe option. So, the more memory size your PC has, the more stable the processing will be. Photogrammetry processes an enormous number of photos. And, 3DF Zephyr will significantly slow down if the GPU doesn’t support CUDA. Please be aware that poor PC performance would compromise GPU performance even if you have a high-performance GPU (CPU causes a bottleneck). However, CPU performance equally plays an important part, so the higher the computational performance is, the more efficiently photos are processed. GPU performance is important for Photogrammetry to process photos. In this ‘PC system requirement’, I summarize the recommended specification and tools for ‘wide-area’ Photogrammetry.
