I'm working on a project with my Raspberry Pi at the moment. I'll give a brief summary of what I'm trying to achieve.

  1. I would like my RPi to take high resolution pictures through a USB webcam at intervals, say every 5 minutes
  2. I would then like to upload each image into the web, preferably to my Dropbox account (Possible?)
  3. I will then set the desktop background settings of my Windows 7 machine to look in the directory where these images are stored
  4. End result: I can set the RPi up on the farm where I grew up so my desktop background will keep me up to date on what's going on up there while I'm stuck behind my desk at work wondering why I didn't become a farmer!

Sound like a fun idea?

So my question at this stage in my project is about your experience with cameras that work well with the RPi and what I should look for the get the highest res possible out of it. Also if anyone knows of any good software for taking picture at intervals that would be useful too! I have read about the 'motion' app but it seems to have issues with high resolution.

All advice/ ideas will be highly appreciated!

Definitely use gphoto2. Here is a great script for installing gphoto2 on the pi: https://github.com/gonzalo/gphoto2-updater/

Note that you can email to a dropbox, so if the Pi is connected to the internet you could have your script email each image capture using mpack.

You can check if your camera is in the list of working hardware (not a complete list), to make sure it will work: http://elinux.org/RPi_VerifiedPeripherals

For working with the camera and taking snapshots etc. you could use motion

Regarding loading the images to an webserver or dropbox: It should be doable to write a small Phyton script to load images onto a web/ftp server. Or you could make your Raspberry Pi accessible from the web / use it as a webserver (for example nginx)

i use gphoto2 package (commandline shoot) with Raspi to shoot (by usb) every X seconds with a Canon DSLR camera and upload it to a local web server. so later, make time lapse videos with it.

I use the dropbox_uploader script. I made a simple photo-capture script which writes to /var/tmp, a fake directory in the memory instead of the sdcard, to reduce sd-card wear! My own script.sh

#!/bin/bash
filename="shot-`date +%s`.jpg"
tmpdir="/var/tmp/"
dropboxfolder="/webcam/"
#Take a picture usinusingg a command which works for your camera, save it to $filename
/home/pi/Dropbox-Uploader/dropbox_uploader.sh -s -q upload $tmpdir$filename $dropboxfolder$filename
/bin/rm $tmpdir$filename

Then chmod +x script.sh and edit /etc/crontab, add the line
*/5 * * * * pi /home/pi/script.sh
(edit to your filename/locations ofcourse)

It works perfect for me.

I'd wait for the 5-megapixel official camera module if I were you.
