我正在通过tcp将我的iPhone中的png图像传输到我的MacBook.MacBook代码来自http://docs.python.org/library/socketserver.html#requesthandler-objects.如何转换图像以用于OpenCV？之所以选择png是因为它们很有效,但可以使用其他格式.

我写了一个测试程序,从文件中读取rawImage,但不知道如何转换它:

# Read rawImage from a file, but in reality will have it from TCPServer
f = open('frame.png', "rb")
rawImage = f.read()
f.close()

# Not sure how to convert rawImage
npImage = np.array(rawImage)
matImage = cv2.imdecode(rawImage, 1)

#show it
cv.NamedWindow('display')
cv.MoveWindow('display', 10, 10)
cv.ShowImage('display', matImage)
cv. WaitKey(0)
