Before I forget: Before a few days ago, I did imaging through the Raspberry Pi camera the following way:
I'd drive the robot a few feet. Then I'd send a command to take a picture. A picture would be sent back to me, and I'd take a look at it. Then I'd dismiss the picture, and drive the robot a little bit more. And so on.
Tedious.
The whole thing was done via Python. I couldn't figure out how to do streaming via Python. So, following streaming instructions here, I set up streaming video via the from the Raspberry Pi camera to a web page.
Now, I get a live stream of the camera as I drive the robot, making it a more fun driving experience.
Unfortunately, it seems to have hosed the picamera Python library, so I don't have access vi Python. Oh, well. For now, I don't need or want it. I'll have to see about reinstalling it or making it live side-by-side with streaming, if possible, if I want it back in the future.
