Raspberry Camera API

Back to Robobot

Raspicam

To be used from C++ direct or through openCV.

A rather short raspberry pi camera API is available from https://www.uco.es/investiga/grupos/ava/node/40. And can be downloaded from https://sourceforge.net/projects/raspicam/files/,

or get the file from sourceforge with no GUI, with:

cd ~/Downloads
wget --no-check-certificate -O raspicam-0.1.9.zip https://downloads.sourceforge.net/project/raspicam/raspicam-0.1.9.zip?r=https%3A%2F%2Fsourceforge.net%2Fprojects%2Fraspicam%2F%3Fsource%3Dtyp_redirect&ts=1486483484&use_mirror=netix

Once fetched and available on the raspberry, then Unpack and install:

unzip raspicam-0.1.9.zip
cd raspicam-0.1.9
mkdir build
cd build
cmake ..
make
sudo make install
sudo ldconfig

The library is installed in /usr/local, and therefore to make cmake find it the path needs to be added to startup configuration, in file ~/.bashrc

nano ~/.bashrc
add at the end:
export CMAKE_PREFIX_PATH=/usr/local/lib
source ~/.bashrc   # to implement export

Test with openCV

raspicam_cv_test

That takes 100 images and saves 3.
