How to open Kinect V2 camera instead of webcam? [closed]
I have a code written in Python and OpenCV. The code works fine on my laptop but how do I open Kinect V2 IR/Depth/RGB camera instead of the laptops webcam?
Here is my code for webcam.py
cap = cv2.VideoCapture(0)
count = 0
while True:
ret, frame = cap.read()
hsv = cv2.cvtColor(frame, cv2.COLOR_BGR2HSV)
lower_blue = np.array([0, 10, 60])
upper_blue = np.array([20, 150, 255])
mask = cv2.inRange(hsv, lower_blue, upper_blue)
res = cv2.bitwise_and(frame, frame, mask=mask)
ref = fill_blacks(mask)
What could be the equivalent of cv2.VideoCapture(0)
? I have a little ROS subscribing code that subscribe to the Kinect V2 IR camera:
class PositionTracker:
def __init__(self):
# subscribe to kinect image messages
self.sub = rospy.Subscriber("kinect2/sd/image_ir", Image, self.image_callback, queue_size=1)
self.bridge = CvBridge()
def image_callback(self,data):
try:
cv_image = self.bridge.imgmsg_to_cv2(data)
except CvBridgeError as e:
print(e)
cv2.imshow("Image window", cv_image)
If I try to do anything inside the def image_calback
function, the Kinect camera will hang. Can anybody help me with this?
