I have been asked to shoot a series of spherical panoramas and link them to form a VR type tour of a building, internal and external. There seem to be a number of products and software packages available without standout products. Nodal Ninja 360Precision seem to produce excellent products.
Any recommendations from someone with lots of experience is this area?
Hi,
The equipment requirements depend on the required output quality. There are solutions that allow to use existing camera equipment, and panorama stitching software like PTGUI is used for the creation of the base 360 degree VR files, e.g. as a single 360x180 degree equirectangular projection file.
Creating a tour, which connects the different vantage points from where the scene can be viewed, usually requires separate software, and as a bit of a learning curve if the tour has additional features added.
From what I've seen, the NodalNinja gear is of decent quality, but for heavier camera equipment I'd prefer something with a more sturdy construction, e.g. as offered by Really Right Stuff. It's usually a joy to work with that modular equipment, although I combine it with components from other manufacturers such as a Click-stop indexing rotator which quickly/repeatably allows to rotate the camera in fixed increment steps.
With a full-frame Fish-Eye lens I take a 360 degree pano in 5 images, 4 are pitched down by 20 degrees, and one points straight up (the Zenith shot). When the ground detail below the camera is complicated, another separate image (the Nadir shot) is taken, but with a bit of planning that can often be unnecessary. A fish-Eye lens that creates circular images can use fewer images, but at slightly lower quality (due to the lower image magnification and edge quality).
I use PTGui Pro for pano stitching, and Pano2VR for the virtual tour creation. Both do a great job, and have excellent support.
If you have no experience with shooting this type of images, it will take a bit of practice to get the hang of it.
Cheers,
Bart
