auto_rula\n\n_auto_rula_ implements the functionality for scoring a pose in 3D space\nusing the [RULA](https://ergo-plus.com/rula-assessment-tool-guide/) system.\n\n## Usage\n\nThe main steps for scoring a pose are:\n\n1. **Normalize the pose**: This step normalizes the position, rotation and\nscale of the pose in order to the following processing easier.\n2. **Project pose onto anatomical planes**: In order to to calculate\njoint angles we first project the pose onto the 3 anatomical planes\n(coronal, sagittal and transverse).\n3. **Calculate joint angles**: Using the normalized pose + the 3 projections\nwe can now calculate angles of all RULA relevant joints.\n4. **Fill out rula-sheet**: We now have all the information to fill out\na modelled RULA sheet, just like in real life.\n5. **Score rula-sheet**: We can now run the calculations described in the\nRULA system to arrive at scores from the measured angles.\n\nIn terms of code, an example pipeline could look like this:\n\n```dart\n// Get a pose from somewhere, for example by extracting it from an image\n// using computer vision\nfinal Pose pose = getPose();\n\n// Normalize the pose\nfinal NormalizedPose normalized = NormalizedPose.normalize(pose);\n\n// Calculate the joint angles for the pose.\n// This requires projecting it onto the anatomical planes.\nfinal PoseAngles angles = PoseAngles.calculate(\n    world: normalized,\n    coronal: ProjectedPose.coronal(normalized),\n    sagittal: ProjectedPose.sagittal(normalized),\n    transverse: ProjectedPose.transverse(normalized),\n);\n\n// We can now fill out a RULA sheet with the angles we calculated.\nfinal RulaSheet sheet = RulaSheet.fromAngles(angles);\n\n// Finally we can score the sheet.\nfinal RulaScores scores = RulaScores.calculateFor(sheet);\n```\n\nFor convenience, the package also includes a method which contains this\npipeline if you are only interested in the final score result.\n\n```dart\nfinal pose = getPose();\nfinal scores = pose.score();\n```\n\n## License\n\nAll source code in this repository is licensed under the\n**MIT License with Commons Clause**.
