The 2D image coordinates of the selected box are printed to the terminal. Run the example code and click + drag on the screen to make a “selection” box.waitKey ( 1 ) & 0xFF # If the 'c' key is pressed, break the while loop if key = ord ( "c" ): break # Close all windows and unload the depth device openni2. imshow ( "Depth Image", img ) key = cv2. rectangle ( img, refPt, refPt, ( 0, 255, 0 ), 2 ) # Display the reshaped depth frame using OpenCV cv2. swapaxes ( img, 0, 1 ) if len ( refPt ) > 1 : img = img. concatenate (( img, img, img ), axis = 0 ) img = np.

I also read that the python-opencv repository is older, outdated, and doesn’t include the opencvcontrib package and therefore people do not recommend installing OpenCV via apt-get because one will be missing features and be running an older, outdated version. append (( x, y )) selecting = False print refPt # Initial OpenCV Window Functions cv2.

This should install OpenCV in your Anaconda.

If the version of python install in your Anaconda is 2.7, the command above should install OpenCV 3.1, but if the version of your python is 3.5, then you should change 'opencv' in the last line to 'opencv3'. open_any () # Start the depth stream depth_stream = dev. #!/usr/bin/python import cv2 import numpy as np from openni import openni2 from openni import _openni2 as c_api # Initialize the depth device openni2.
