Agisoft photoscan mac5/8/2023 ![]() ![]() It would, for example, take much longer to align the images and generate a sparse point cloud if the number of tie points is increased to 80,000 and pair preselection is turned off. It wasn't really clear if the 40 hours required to generate the dense point cloud (Step 2 of the Photoscan workflow) on your laptop also included the time to align the images and generate the sparse point cloud (Step 1 of the workflow). ![]() I would also check the quality of the images (you can do this in the Photos pane) and make sure you've carefully optimized the sparse point cloud before you try generating the dense point cloud. It used to be said that Photoscan doesn't run as well with multithreading enabled, but I'm not sure if this is true of the current version of Photoscan, so I'd try it and see. If you have XCode on your laptop, you might try also disabling multithreading by opening "Instruments" and using Preferences. You should certainly disable one core of the CPU as recommended in the Photoscan User's Guide, (using Preferences and the OpenCL tab in Photoscan) to take advantage of the discrete GPU on your laptop. Processing time depends on a number of factors and settings in Photoscan, which makes the most use of discrete graphics cards (GPUs) during the step of generating a dense point cloud from a sparse cloud, so I'd focus on getting the GPU running. That said, I've easily processed much larger datasets on a 2012 Mac Mini that has lesser specs (Quad i7 processor with integrated HD 4000 graphics, and 16 Gb of RAM) than your newer Macbook Pro, so I don’t think the specs of your MacBook are the concern-it’s more likely to be the settings you’re using or possibly the image quality. And for whatever reason, Photoscan seems to play nicer with Nvidia graphics cards than with the Radeon GPUs, perhaps because it takes advantage of the CUDA architecture on Nvidia cards. ![]() You'll probably do better running Photoscan in OS X rather than running it in Windows through Parallels on a Macbook.
