Basically there are 2 components in the process: the stitching software which creates a single panoramic photo from many separate image sources, then there is the panoramic viewer, which distorts the image as you change your POV to simulate what your eyes would see if you were actually there.

My company uses the <a href="http://papervision3d.org" rel="nofollow noreferrer">Papervision3D</a> flash render engine, and maps a panoramic image (still image or video) onto a 3D sphere. We found that using a spherical object with about 25 divisions along both the axes gives a much better visual result than mapping the same image on the six faces of a cube. Check it for yourself at <a href="http://www.panocast.com" rel="nofollow noreferrer">http://www.panocast.com</a>.

Actually, you could of course distort your image in advance, so that when it is mapped on the faces of a cube, its perspective is just right, but this requires the complete rerendering of your imagery.

With some additional "magic", we can also load still images incrementally, as needed, depending on where the user is looking and at what zoom level (not unlike Google Street View does).

blocks|key|976909|text|就谷歌的实际业务而言，博克拥有这一权利。我不确定确切的细节(即使我知道，我也不确定我是否能公布细节)，但谷歌将个人360度街景场景存储在equirectangular+representation中供服务。然后，flash播放器使用一系列affine+transformations以透视方式显示图像。仿射变换是近似的，但足够好地聚合为一个像样的整体图像。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|976910|服务图像的计算非常复杂，因为必须完成许多阶段的图像处理，以去除面部，解决bloom等。在实际拼接全景图方面，有许多用于此的算法(wikipedia+article)。我只想指出一件有趣的事，作为思考的食粮，在街景的360度全景图中，你可以看到图像底部的道路，那里的汽车上没有摄像头。这就是缝合。|976911|entityMap|0|LINK|mutability|MUTABLE|url|http://en.wikipedia.org/wiki/Plate_carr%25C3%25A9e_projection|1|http://en.wikipedia.org/wiki/Affine_transformation|2|http://en.wikipedia.org/wiki/Image_stitching^0|1W|U|0|3B|M|1|0|1S|H|2|0^^$0|@$1|2|3|4|5|6|7|R|8|@]|9|@$A|S|B|T|1|U]|$A|V|B|W|1|X]]|C|$]]|$1|D|3|E|5|6|7|Y|8|@]|9|@$A|Z|B|10|1|11]]|C|$]]|$1|F|3|-4|5|6|7|12|8|@]|9|@]|C|$]]]|G|$H|$5|I|J|K|C|$L|M]]|N|$5|I|J|K|C|$L|O]]|P|$5|I|J|K|C|$L|Q]]]]

In terms of what Google actually does, Bork had this right. I'm not sure of the exact details (and not sure I could release the details even if I did), but Google stores individual 360 degree streetview scenes in an <a href="http://en.wikipedia.org/wiki/Plate_carr%C3%A9e_projection" rel="nofollow noreferrer">equirectangular representation</a> for serving. The flash player then uses a series of <a href="http://en.wikipedia.org/wiki/Affine_transformation" rel="nofollow noreferrer">affine transformations</a> to display the image in perspective. The affine transformations are approximate, but good enough to aggregate to a decent image overall.

The calculation of the served images is very involved, since there are many stages of image processing that have to be done, to remove faces, account for bloom, etc. etc. In terms of actually stitching the panoramas, there are many algorithms for this (<a href="http://en.wikipedia.org/wiki/Image_stitching" rel="nofollow noreferrer">wikipedia article</a>). Just one interesting thing I'd like to point out though, as food for thought, in the 360 degree panoramas on street view, you can see the road at the bottom of the image, where there was no camera on the cars. Now that's stitching.

It is pretty impressive to watch a video that allows panning in every direction... which is what street view is without the bandwidth to support the full video.

For those wondering how the Google VR Photographers and editers add the ground to their Equirectangular panoramas, check out the feature called Viewpoint Correction, as seen in software like PTGui:

ptgui.com/excamples/vptutorial.html

(Note that this is NOT the software used by Google)

If you take a closer look at the ground in street view, you see that the stitching seems streched, and sometimes it even overlaps with information from the viewpoint next to the current one. (With that I mean that you can see something in one place, and suddenly that same feature is shown as the ground in the next place, revealing the technique used for the ground stitching).
