• Verify Python Installation

python --version

• Upgrade pip

pip install --upgrade pip

• Install Pyrealsense2

pip Install pyrealsense2==2.54.2.5684

• Install OpenCV

pip Install opencv-python

• Install Open3d

pip install open3d==0.18.0

• Install Numpy

pip install numpy

To verify the installations, run this test script:

import cv2
import open3d as o3d
import pyrealsense2 as rs

print("OpenCV version:", cv2.__version__)
print("Open3D version:", o3d.__version__)
print("pyrealsense2 version:", rs.__version__)
