II. Ci t ln Raspberry Pi:

- Sau khi np h iu hnh Raspbian vo th nh, cm th, cm cp HDMI, bn phm,

chut v dy mng vo Raspberry Pi.

- Cm ngun vo, ta s thy mn hnh khi ng ca Raspberry Pi vo thng Raspi-

config.

- Chn dng th 3- Enable boot to Desktop/Scratch. Sau thot ra chn Finish

khi ng li Raspberry Pi v hon tt qu trnh ci t.

- Khi Raspi khi ng xong, ta g username l pi, password l raspberry, sau g

startx vo mn hnh giao din RasPi.

III. Config c bn cho Raspberry Pi:

1) Config Network :

- Ta vo Terminal trn desktop. G lnh: sudo nano /etc/network/interfaces

chnh thng s ci t cho mng dy, y trng hp ta t ip tnh laptop c

th kt ni vo bng giao thc vnc.


6 | P a g e

y ta t IP ca Raspi l 192.168.0.210, IP mng l 192.168.0.1.

Note: Nu mun a ch IP t cp pht th ta ch cn sa li dng th 3 thnh

iface eth0 inet dhcp v xa cc dng th 4 tr i.

- lu li bm t hp phm Ctrl + O ==> Enter ==> Ctrl + X.

- Sau ta g lnh sudo reboot khi ng li card mng.

2) iu khin Raspberry Pi t xa qua 1 my khc:

- Ti terminal g:

sudo raspi-config : vo mn hnh config raspi

Chn mc Advance Options SSH Enable ri OK.

- Ci t SSH client trn my tnh Windows. Download phn mm PuTTY ti

http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html .


7 | P a g e

- Trn giao din PuTTY ta nhp a ch 192.168.0.210 ca Raspi vo Hostname ri

bm Open.

- Ci t VNCServer ln Raspi. Ti terminal ta g:

sudo apt-get install tightvncserver

tightvncserver

vncserver:1 geometry 1024x768 depth 24

- Ci t VNCViewer ti my client mun truy cp vo Raspi. Download ti

http://www.realvnc.com/download/viewer/ . Chy vncviewer v in

192.168.0.210:5901 vo VNC Server. Sau bm Connect l ta hon ton s

dng c Raspi thng qua iu khin t xa.

IV. Ci t OpenCV ln Raspberry Pi:

1) Ci t cc gi cn thit h tr OpenCV:

- Config ssh v camera:

sudo raspi-config


8 | P a g e

ssh-->enable : bt ssh.

camera-->enable : bt camera.


9 | P a g e

// cp nht driver mi nht.

sudo apt-get update

sudo apt-get upgrade


10 | P a g e

// kim tra camera.

lsusb

sudo apt-get install guvcview

guvcview : bt th camera.

// ci t synaptic.

sudo apt-get install synaptic

// ci t python scipy stack.

sudo apt-get install python-numpy python-scipy python-matplotlib python-

pandas python-sympy python-nose


11 | P a g e

2) Download v ci t OpenCV 2.4.8:

// download opencv bn 2.4.8

wget http://sourceforge.net/projects/opencvlibrary/files/opencv-

unix/2.4.8/opencv-2.4.8.zip/download

// ci t mi trng pht trin cho opencv.

sudo apt-get install build-essential cmake pkg-config


12 | P a g e

sudo apt-get install default-jdk ant

sudo apt-get install libgtkglext1-dev

sudo apt-get install bison

sudo apt-get install qt4-dev-tools libqt4-dev libqt4-core libqt4-gui

sudo apt-get install v4l-utils


13 | P a g e

sudo apt-get install qtcreator ( C th ci hoc khng).

// ci t opencv.

unzip opencv-2.4.8.zip

cd opencv-2.4.8

mkdir build

cd build

cmake D CMAKE_BUILD_TYPE=RELAESE D

INSTALL_C_EXAMPLES=ON D

INSTALL_PYTHON_EXAMPLES=ON D BUILD_EXAMPLES=ON

D WITH_QT=ON D CMAKE_INSTALL_PREFIX=/usr/local D

14 | P a g e

Make

sudo make install


15 | P a g e

// sa cc file config link th vin.

sudo nano /etc/ld.so.conf.d/opencv.conf

thm vo dng:

/usr/local/lib


16 | P a g e

sudo ldconfig

sudo nano /etc/bash.bashrc

thm vo cui:

PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/usr/local/lib/pkgconfig

export PKG_CONFIG_PATH


17 | P a g e

Lu cc file li.

3) Chy code mu OpenCV:

// chy code mu ca opencv.

cd /opencv-2.4.8/samples/c

chmod +x build_all.sh

./build_all.sh

// chy facedetect.

./facedetect

// chy code mu python.
