Using Python To Install OpenCV 3.4x on Banana Pi M2P(H3)
- Install OpenCV 3.4x on Banana Pi M2P(H3) we use Banana Pi BPI-M2+ to this test.I will show you how to install OpenCV on BPI M2P(H3) in this thread.
- Step 1: Install Dependency Packages**
apt-get update apt-get install libprotobuf-dev libleveldb-dev libsnappy-dev libhdf5-serial-dev protobuf-compiler apt-get install libgflags-dev libgoogle-glog-dev liblmdb-dev apt-get install build-essential cmake pkg-config libjpeg-dev libtiff5-dev libjasper-dev libpng12-dev apt-get install libavcodec-dev libavformat-dev libswscale-dev libv4l-dev v4l-utils libxvidcore-dev libx264-dev ffmpeg apt-get install libgtk2.0-dev libatlas-base-dev gfortran python2.7-dev python3-dev checkinstall
- Step 2 : Download OpenCV Code
git clone https://github.com/opencv/opencv.git --branch 3.4.0 git clone https://github.com/opencv/opencv_contrib.git --branch 3.4.0
- Step 3 : cmake OpenCV Code
cd <path>/opencv mkdir build cd build cmake -D CMAKE_BUILD_TYPE=Release -D CMAKE_INSTALL_PREFIX=/usr/local -D PYTHON_INCLUDE_DIR=/usr/bin/python -D OPENCV_EXTRA_MODULES_PATH=<path>/opencv_contrib/modules ..
- Step 4 : Using python to test camera
python readvideo.py
import numpy as np import cv2 cap = cv2.VideoCapture(1) #/dev/video1
while(True): # Capture frame-by-frame ret, frame = cap.read()
# Our operations on the frame come here
#gray = cv2.cvtColor(frame, cv2.COLOR_BGR2GRAY)
# Display the resulting frame
cv2.imshow('frame',frame)
if cv2.waitKey(1) & 0xFF == ord('q'):
break
# When everything done, release the capture cap.release() cv2.destroyAllWindows()
- FAQ:
If you meet problem like this：
replace "/usr/bin/python" by "/usr/bin/python2.7" Or use "ln -s /usr/bin/python2.7 /usr/bin/python"
