Please provide a tutorial on how to use Camera and Lidar in Simulation

[Kavya-812]

Describe the the feature you would like

As of now, I could not find a specific node to run the camera to apply Open CV algorithms in the simulation. Please provide a solution for this

Motivation and impact

Testing and Validation: By simulating camera input and applying computer vision algorithms within the simulation environment, developers can test and validate their vision-based algorithms without requiring physical hardware. This reduces the need for costly and time-consuming experimentation with real robots.
Algorithm Development: Providing a simulated camera node enables researchers and developers to iterate rapidly on their computer vision algorithms. They can fine-tune parameters, experiment with different approaches, and optimize algorithms without needing access to physical robots.
Education and Training: Students and enthusiasts learning about robotics and computer vision can benefit from a simulated camera node. It allows them to experiment with vision-based robotics concepts in a controlled environment, facilitating hands-on learning and skill development.
Integration with ROS Ecosystem: ROS (Robot Operating System) is widely used in robotics research and development. Integrating a camera node into the ROS ecosystem allows users to leverage existing tools, libraries, and resources for image processing and robotics.
Collaborative Development: A standardized camera node interface enables collaborative development and knowledge sharing within the robotics community. Developers can easily share code, algorithms, and simulation environments, fostering innovation and collaboration.
