Today it was whole lot fun exploring the possibilities with Raspberry Pi and DSLR for taking time lapse video. Latter I moved from Raspberry Pi to CubieTruck so that I can attach hard drive for large storage capacity. I found a small command line utility gphoto which can be used as remote control for a DSLR. I can use the utility to click a photo and stream the picture to the Pi.
The version I found on the apt-get was little old so I had to compile my own version. Then you can play around with the gphoto command to play around.
sudo su cd /root apt-get install -y libltdl-dev libusb-dev libexif-dev libpopt-dev libgd2-xpm libgd2-xpm-dev libxml2-dev ffmpeg mkdir gphoto2 cd gphoto2/ wget http://ftp.de.debian.org/debian/pool/main/libu/libusbx/libusbx_1.0.11.orig.tar.bz2 tar xjvf libusbx_1.0.11.orig.tar.bz2 cd libusbx cd libusbx-1.0.11/ ./configure make make install cd .. wget http://downloads.sourceforge.net/project/gphoto/libgphoto/2.5.2/libgphoto2-2.5.2.tar.bz2 tar xjf libgphoto2-2.5.2.tar.bz2 cd libgphoto2-2.5.2 ./configure make make install cd .. wget http://downloads.sourceforge.net/project/gphoto/gphoto/2.5.2/gphoto2-2.5.2.tar.gz tar xzvf gphoto2-2.5.2.tar.gz cd gphoto2-2.5.2 ./configure make make install cd .. ldconfig cd /root rm -rf gphoto2/
EDIT: Forgot to mention about the cronjob
#!/bin/sh filecount=$(ls -l //cdn.imthi.com/mnt/storage/timeLapse/*.jpg |grep -v '/$'| wc -l) for count in 1 2 3 4 5 6 do filecount=$(($filecount + 1)) filename=$(printf "frame_%09d.jpg" $filecount) /usr/local/bin/gphoto2 --set-config autofocusdrive=1 --capture-image-and-download --force-overwrite --filename=/mnt/storage/timeLapse/$filename sleep 7 done
Last but not the least to make the images into a movie
ffmpeg -f image2 -i frame_%09d.jpg time-lapse.mp4
It was fun I hope you will enjoy doing it 😉
