Opencv Python display raw image

Question

I can\'t figure out how to display a raw image which contains 640x480 pixel information, each pixel 8 bit. (Gray image)

I need to go from an np array to Mat format to

Answer 1

.RAW files are not supported in OpenCV see imread,

But the file can be opened with Python and parsed with Numpy

import numpy as np
fd = open('flight0000.raw', 'rb')
rows = 480
cols = 640
f = np.fromfile(fd, dtype=np.uint8,count=rows*cols)
im = f.reshape((rows, cols)) #notice row, column format
fd.close()

This makes a numpy array that can be directly manipulated by OpenCV

import cv2
cv2.imshow('', im)
cv2.waitKey()
cv2.destroyAllWindows()
