首先需要保证你的NanoPC-T3-Plus能连外网
sudo apt-get updatesudo
sudo apt-get install libcv-dev libopencv-devsudo
sudo apt-get install python-opencv
环境搭建后测试python中是否可以使用opencv
编写测试代码：
import numpy as npimport
cv2cap = cv2.VideoCapture(0)cap.set(3,640) # set Widthcap.set(4,480) # set Heightwhile(True): ret, frame = cap.read()
frame = cv2.flip(frame, -1) # Flip camera vertically
gray = cv2.cvtColor(frame, cv2.COLOR_BGR2GRAY)
cv2.imshow('frame', frame)
cv2.imshow('gray', gray)
k = cv2.waitKey(30) & 0xff
if k == 27: # press 'ESC' to quit
break
cap.release()
cv2.destroyAllWindows()
运行： python opencv_test.py
