Miscellaneous utilities for working with camera data

Project description

# cv_utils

Miscellaneous utilities for working with camera data:

  • Utilities for working with images and videos (many of which use OpenCV “under the hood”)

  • Functions which support basic visualization of image and object points

  • Functions which support camera calibration using OpenCV and/or COLMAP

## Task list

  • Add option to project_points() to include points that are projected inside the frame with distortion but just outside the frame without

  • Integrate (Docker-based?) version of OpenCV which supports proprietary codecs (primarily mp4)

  • Consider implementing additional objects/classes (e.g., Camera)

  • Move Wildflower-specific functionality into separate package

  • Add additional functions so we can eliminate OpenCV as dependency for wf-process-pose_data, wf-video-io, wf-camera-calibration, etc.

  • Implement more performant replacement for cv.triangulatePoints()

  • Augment drawing functions so they can handle multiple objects, Nan values, etc.

  • Get ride of unused/buggy functions in core

  • Clean up color conversion helper functions (use OpenCV functions?)

  • Move 3D projection code into its own submodule

  • Convert drawing functions in core to object-oriented Matplotlib interface?

  • Convert drawing functions in core to OpenCV drawing API?

  • Fix comments in generate_camera_pose() (currently describes yaw inaccurately)

  • Clean up handling of coordinates (shouldn’t OpenCV accept numpy arrays?)

  • Clean up handling of large integer coordinates
