Hi ,

I am working on building a custom application on RB5 to get two camera inputs do some processing(stereo rectification and translation) and render it on two separate displays . Can you suggest some ways to do it on RB5 ? I have the cameras up and working with gstreamer command. All I need is a way to get frames in application and steps to build the application. Is there any way I can do it on application or need to create a CHI-CDK custom node to process them?

Use Opencv to capture the frames through the camera and convert those frames into images for visualization.


For reference, you can check the below script.

import cv2
def capture_single_frame_resize_and_save(file_path="single_frame", camera_index=0, width=224, height=224): 
    # Initialize video capture 
    cap = cv2.VideoCapture(camera_index) 
    # Capture a single frame 
    ret, frame = 
    # If the frame is successfully captured 
    if ret: 
        # Resize the frame 
        resized_frame = cv2.resize(frame, (width, height)) 
        # Save the frame in .jpg format 
        image_file_path = f"{file_path}.jpg"  # Update file name with .jpg extension 
        cv2.imwrite(image_file_path, resized_frame) 
        print("Resized frame saved as:", image_file_path)
