The code is the following:
import numpy as np
import cv2
import time
from matplotlib import pyplot as plt
cv2.namedWindow( "Left", cv2.WINDOW_AUTOSIZE );
cv2.namedWindow( "Right", cv2.WINDOW_AUTOSIZE );
cam1 = cv2.VideoCapture(1)
cam1.set(cv2.CAP_PROP_FRAME_WIDTH,384)
cam1.set(cv2.CAP_PROP_FRAME_HEIGHT,216)
cam2 = cv2.VideoCapture(2)
cam2.set(cv2.CAP_PROP_FRAME_WIDTH,384)
cam2.set(cv2.CAP_PROP_FRAME_HEIGHT,216)
stereo = cv2.StereoBM_create(numDisparities=16, blockSize=15)
while(True):
# Capture frame-by-frame
ret, frame1 = cam1.read()
ret, frame2 = cam2.read()
# Display the resulting frame
cv2.imshow("Left",frame1)
cv2.imshow("Right",frame2)
disparity = stereo.compute(frame1,frame2) # kaput as it wants CV_8UC1 matrix
plt.imshow(disparity,'gray')
plt.show()
if cv2.waitKey(1) & 0xFF == ord('q'):
break
# When everything done, release the capture
cam1.release()
cam2.release()
cv2.destroyAllWindows()
Computing disparity is kaput as the image frame appears to be uint8 while the disparity computation wants CV_8UC1. Examples I have found to do the conversion are either in C++ or not in OpenCV 3.2 Pythonesque.
What is the conversion approach for uint8 to CV_8UC1 in OpenCV 3.2 Python please?
