Rascberry上的opencv-3.0.0错误

Question

我在rasperry Pi上的Opencv-3.0.0中出现此错误

enter cod# OpenCV_test1.py

此程序以相同的目录名打开文件＆＃34; image.jpg＆＃34;并显示原始图像和原始图像的Canny边缘

导入cv2 导入numpy为np import os

＃

def main（）：     imgOriginal = cv2.imread（＆＃34; image.jpg＆＃34;）#open image

if imgOriginal is None:                             # if image was not read successfully
    print "error: image not read from file \n\n"        # print error message to std out
    os.system("pause")                                  # pause so user can see error message
    return                                              # and exit function (which exits program)
# end if

imgGrayscale = cv2.cvtColor(imgOriginal, cv2.COLOR_BGR2GRAY)        # convert to grayscale

imgBlurred = cv2.GaussianBlur(imgGrayscale, (5, 5), 0)              # blur

imgCanny = cv2.Canny(imgBlurred, 100, 200)                          # get Canny edges

cv2.namedWindow("imgOriginal", cv2.WINDOW_AUTOSIZE)        # create windows, use WINDOW_AUTOSIZE for a fixed window size
cv2.namedWindow("imgCanny", cv2.WINDOW_AUTOSIZE)           # or use WINDOW_NORMAL to allow window resizing

cv2.imshow("imgOriginal", imgOriginal)         # show windows
cv2.imshow("imgCanny", imgCanny)

cv2.waitKey()                               # hold windows open until user presses a key

cv2.destroyAllWindows()                     # remove windows from memory

return

＃

如果名称 ==＆＃34; 主要＆＃34;：     main（）的

这里

这就是错误 python OpenCV_test1.py   文件＆＃34; OpenCV_test1.py＆＃34;，第4行     导入cv2 import numpy as np import os                     ^ SyntaxError：语法无效

Answer 1

导入必须分开（或用分号分隔，但请不要）。

更改

import cv2 import numpy as np import os

到

import cv2
import numpy as np
import os
