You can also use the ZED as a standard UVC camera in OpenCV to capture raw stereo video using the code snippet below. To get rectified images and calibration with OpenCV, use the native (Python) capture sample available onGitHub. importcv2importnumpy# Open the ZED cameracap=cv2.VideoCapture(...

importcv2cap=cv2.VideoCapture(0) The default camera, usually identified as index 0, is used in this example. However, if there are multiple cameras connected, a different device index may need to be specified. When specifying the device index, it's important to be mindful of some ...
First, we import OpenCV using the line, import cv2 Next, we read in the image, which in this case is, Boxes.png We then create a grayscale version of the image. In order to use the harris corner detection method, the grayscale image must be converted to float32 type. ...
Instead, we only want to normalize a portion of the image. We can define that portion in the mask so that normalization will only be performed on the masked portion. For example, let’s reduce the glare present in an image using the normalize() function. See the code below. import cv2...
