How to get image from robot

create RobocupVision proxy
call vision.getBGR24Image (or other functions for different formats)
convert binary data to numpy.array with numpy.fromstring
convert to other image format (like RGB) with OpenCV



In [8]:

    
%matplotlib inline

from naoqi import ALProxy
import numpy as np
import matplotlib.pyplot as plot
import cv2

vision = ALProxy('RobocupVision', 'nao1.local', 9559)

cameraId = 0 # 0 for
data = vision.getBGR24Image(cameraId)
image = np.fromstring(data, dtype=np.uint8).reshape((480, 640, 3))

rgb_img = cv2.cvtColor(image, cv2.COLOR_BGR2RGB)
plot.imshow(rgb_img)
