The USPTO routinely awards utterly bogus patents - perpetual motion machines, add 2 + 2 "using a computer" or "using the Internet" or "using a mobile phone", the list is endless.
This is a good case study for how sometimes, the invention is really easy but nobody has much use for it. Before Google, the only people who'd want to hide a small camera inside a walking stick would rather not advertise that they're doing so.
What would have been interesting is the navigation system. A walking stick is a pretty harsh environment for an IMU, and making IMUs small and light is a challenge. But the patent doesn't address the details, just says the stick must contain a GPS and/or an IMU. Google goes on to claim a "method" of associating location information (from a GPS and/or an IMU) with an image. The "method" is part c) of claim 10, and it's a good example of a bogus "method" claim where what's claimed is a result, not a method. Claim 11 is worse. There's nothing novel about using photos to build a "simulation" of an environment (i.e. Google Street View, Google Earth.) But they're claiming a patent on the method of "use a camera-on-a-stick-with-a-floor-switch to do something we already know how to do with any camera."
