wf-cv-utils 3.3.0

Miscellaneous utilities for working with camera data

# 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
