GoPro Hero 3 White

Makes a lot of use of this documentation: https://github.com/KonradIT/goprowifihack/blob/master/HERO3/WifiCommands.md Python script that controls the GoPro via REST endpoints on the camera's build-in wifi AP. One drawback to this method is that the GoPro API only works over the AP that the camera broadcasts, which is not very strong or fast. The result is that it takes a long time from captures to transfer for each image (around 20 seconds), and it will be difficult to capture images any faster.

Routes Used

• http://10.5.5.9/bacpac/SH?t=goprohero&p=%01 - Activate shutter (take single image)
• http://10.5.5.9:8080/gp/gpMediaList - Retrieve media list from GoPro
• http://10.5.5.9:8080/videos/DCIM/[DIRECTORY]/[IMAGENAME] - Download image with path
• http://10.5.5.9/camera/DA?t=goprohero - Delete images on camera (so that SD card won't fill up)

Webcam

Bash script that controls the webcam with fswebcam, which should be one of the faster options. Round-trip times are shorter, 5-6 seconds, and the connection is safer (direct cable as opposed to wireless). The

Notes

• rsync in batches?
  • --time-limit 30 // transfer for 30 minutes and then stop.
  • --remove-source-files // remove files from beaglebone as they are transferred.
• Local mass storage might be a better option then trying to transfer these back to the cluster.
• do we need to take pictures all year? Only during bright months?

Working on reserver. Webcam takes a picture once every 1.77 seconds, 2034 images in one hour, 529MB. This *24 means we getting 12,696MB of data per day (12.7GB). With a 1000GB partition for photos, this gives us about 78 days of space.

webcam_capture2.sh - ACTUALLY takes a picture once per second, based on epoch. This is almost double the space usage, about 21.5GB per day, 46 days of storage in a 1TB partition.
