	=~~=Raspberry Pi~~ Timelapse ~~Photo=~~=		=Timelapse Scripts=

	~~===Software===~~		There are a couple of different scripts available, depending on your hardware, what library you're using, how much control you need over your images, whether you need video, etc.

	~~Since~~ I ~~hadn~~'~~t connected my Pi to the net in~~ a ~~while, the first thing I did was~~ to ~~update the package manager~~:		==Picamera library (outmoded)==

			Not using this method, since I completely gave up on the picamera (the stupid little ribbon cable camera that is designed specifically for the Pi). It sucks. But if you're using it, here's a script to take timelapse photos with it:

			'''lapse.py'''

	<pre>		<pre>
	~~sudo apt~~-~~get update~~		import picamera
			from datetime import datetime
			import time
			import os

			camera = picamera.PiCamera()

			lapse_dir = datetime.strftime(datetime.now(),"timelapse_%Y%m%d-%H%M%S")
			os.system('mkdir '+lapse_dir)

			while True:

			prefix = datetime.strftime(datetime.now(),"%Y%m%d-%H%M%S")
			filename = lapse_dir+"/"+prefix+".jpg"

			camera.capture(filename)
			print "Saving photo to %s"%(filename)

			time.sleep(2)
	</pre>		</pre>

	~~Next~~, ~~I upgraded~~ the ~~operating system:~~		==Using fswebcam==

			fswebcam is a fast simple unix utility for grabbing photos from USB webcams. This is a command line utility with very few options, but it gets the job done. Here's a sample script that shows how to set a couple of useful flags for the fswebcam program.

			'''relapse.py'''

	<pre>		<pre>
	~~sudo apt-get dist-upgrade~~		import subprocess
	~~</pre>~~		from datetime import datetime
			import time
			import os

	~~With all of the updating and upgrading out of the way~~, ~~I moved on to the actual Raspberry Pi camera itself~~. ~~There is a Python module to control the Pi camera~~, ~~available through aptitude:~~		lapse_dir = datetime.strftime(datetime.now(),"timelapse_%Y%m%d-%H%M%S")
			subprocess.call(['mkdir',lapse_dir])

	~~<pre>~~		while True:
	~~sudo apt-get install python-picamera python-picamera-docs~~
	~~</pre>~~

	~~However, I was still not able to use my camera~~, ~~because I had to run the Raspberry Pi configuration program~~. ~~To run it:~~		prefix = datetime.strftime(datetime.now(),"%Y%m%d-%H%M%S")
			filename = lapse_dir+"/"+prefix+".jpg"

	~~<pre>~~		subprocess.call(['fswebcam','-r','1280x1024','--rotate','90','--no-banner',filename])
	~~sudo raspi~~-~~config~~
	~~</pre>~~

	~~You enable the Raspberry Pi camera in the configuration menu.~~		print "Saving photo to %s"%(filename)

	~~===Setup===~~		time.sleep(2)

	~~The setup I had used one of [http:~~//www.adafruit.com/products/1367 these] as the camera. This is a whopping 5 MP, which is as good as a point-and-shoot, except it's extremely tiny. I was able to get it hooked up to my Raspberry Pi and working just fine with the above steps.		</pre>

	You can use Python code to trigger the camera to take a picture, and you can specify a filename to save to. Here's a quick script I hacked together to take a picture every 2 seconds, and save it to sequentially-numbered files (0001.jpg, 0002.jpg, etc.):		==SimpleCV==

	~~<source lang="python">~~		{{Main\|SimpleCV}}
	~~# pic.py~~

	import ~~picamera~~		This is the optimal method, since [[SimpleCV]] provides an extremely useful set of functions for image processing. Here's a script for obtaining images using the SimpleCV library in a Python script:

			<pre>
			from SimpleCV import Camera
			import os
	import time		import time
			from datetime import datetime

			cam = Camera()
			time.sleep(0.1)

	~~camera~~ = ~~picamera~~.~~PiCamera~~()		lapse_dir = datetime.strftime(datetime.now(),"timelapse_%Y%m%d-%H%M%S")
			os.system('mkdir '+lapse_dir)

	~~i = 0~~
	while True:		while True:

	filename = "~~%04d~~.jpg"~~%(i)~~		prefix = datetime.strftime(datetime.now(),"%Y%m%d-%H%M%S")
			filename = lapse_dir+"/"+prefix+".jpg"

	~~camera~~.~~capture~~(filename)		img = cam.getImage()
			img.save(filename)
	print "Saving photo to %s"%(filename)		print "Saving photo to %s"%(filename)

	~~i += 1~~
	time.sleep(2)		time.sleep(2)

	</~~source~~>		</pre>

	To run this, I use screen. I log in remotely, then run the <code>screen</code> command. In that screen I run <code>python pic.py</code>. It will print out as it progresses. Running it with screen allows you to disconnect and leave the Pi unattended.

==Raspberry Pi Timelapse Photo==

===Software===

Since I hadn't connected my Pi to the net in a while, the first thing I did was to update the package manager:

<pre>
sudo apt-get update
</pre>

Next, I upgraded the operating system:

<pre>
sudo apt-get dist-upgrade
</pre>

With all of the updating and upgrading out of the way, I moved on to the actual Raspberry Pi camera itself. There is a Python module to control the Pi camera, available through aptitude:

<pre>
sudo apt-get install python-picamera python-picamera-docs
</pre>

However, I was still not able to use my camera, because I had to run the Raspberry Pi configuration program. To run it:

<pre>
sudo raspi-config
</pre>

You enable the Raspberry Pi camera in the configuration menu.

===Setup===

The setup I had used one of [http://www.adafruit.com/products/1367 these] as the camera. This is a whopping 5 MP, which is as good as a point-and-shoot, except it's extremely tiny. I was able to get it hooked up to my Raspberry Pi and working just fine with the above steps.

You can use Python code to trigger the camera to take a picture, and you can specify a filename to save to. Here's a quick script I hacked together to take a picture every 2 seconds, and save it to sequentially-numbered files (0001.jpg, 0002.jpg, etc.):

<source lang="python">
# pic.py

import picamera
import time

camera = picamera.PiCamera()

i = 0
while True:

filename = "%04d.jpg"%(i)

camera.capture(filename)
print "Saving photo to %s"%(filename)

i += 1
time.sleep(2)

</source>

To run this, I use screen. I log in remotely, then run the <code>screen</code> command. In that screen I run <code>python pic.py</code>. It will print out as it progresses. Running it with screen allows you to disconnect and leave the Pi unattended.
