Image Common

image_common - ROS Wiki

In ROS (Robot Operating System), the image_common stack provides a set of packages and tools for handling images in ROS. It facilitates the integration of cameras and image processing functionalities into ROS-based systems. Here are the primary components of the image_common stack:

1. image_transport:

   • Manages the transport of images in ROS.

   • Provides transparent compression/decompression for image topics.

   • Allows image data to be published and subscribed to using various transport methods (e.g., raw, compressed, theora).

2. camera_info_manager:

   • Manages camera calibration data.

   • Provides a standardized way to access and store camera calibration parameters.

   • Ensures that image data can be corrected for lens distortion and other camera-specific effects.

3. camera_calibration_parsers:

   • Reads and writes camera calibration parameters from files.

   • Supports various formats such as YAML and ini.

   • Facilitates easy loading and saving of camera calibration data.

4. polled_camera:

   • Supports cameras that require polling to capture images.

   • Provides a mechanism for capturing images on demand rather than continuously.

5. compressed_image_transport:

   • Extends image_transport to support compressed image formats.

   • Reduces the bandwidth required for transmitting image data by using JPEG or PNG compression.
