ASTM E2919-22 PDF

Overview

ASTM E2919-22: Standard Test Method for Evaluating the Performance of Systems that Measure Static, Six Degrees of Freedom (6DOF), Pose provides a reliable, repeatable method for assessing the performance of static pose measurement systems. These systems, capable of measuring the position and orientation (pose) of rigid objects across six degrees of freedom, are widely used in industries such as manufacturing, medicine, material handling, construction, and aerospace.

This ASTM standard defines key metrics and procedures for collecting and analyzing data to quantitatively assess a pose measurement system’s ability to measure static objects. By offering a common benchmark, the standard enables users to compare the performance of different 6DOF pose measurement systems and verify claims made by system vendors within application-specific environments.

Key Topics

• Performance Evaluation: Provides specific test methods, including statistical procedures, to determine absolute and relative error in both position and orientation.
• Absolute and Relative Pose Measurement: Assesses both the static pose (position and orientation) and changes in pose between two positions.
• Sampling Requirements: Specifies sample sizes and randomization within the work volume to ensure robust performance assessments.
• Reference Systems: Outlines the need for highly accurate reference systems (such as laser trackers or coordinate measurement machines) for benchmarking.
• Reporting and Documentation: Requires standardized reporting templates that document all key findings, test conditions, and statistical analyses.
• Environmental Conditions: Ensures that testing is conducted under conditions suitable for both the pose measurement system and intended application.
• Statistical Validation: Employs statistical tests (e.g., Z-test, quantile error, maximum permissible error, and precision error tests) to objectively determine conformity with vendor specifications.

Applications

The ASTM E2919-22 standard is crucial for a variety of 6DOF pose measurement system users and vendors by offering:

• Product Benchmarking: Provides a standardized test method for comparing new and existing pose measurement systems in the market, assisting procurement decisions.
• System Verification: Enables end users to objectively verify that a system’s performance aligns with application-specific requirements instead of relying solely on vendor specifications.
• Performance Optimization: Offers manufacturers and developers metrics and methods to evaluate, improve, and communicate system capabilities in static measurement scenarios.
• Industrial Implementation: Essential for fields such as:
  • Robotics and Automation: Accurately verifying robotic arm positioning or spatial orientation.
  • Aerospace and Aviation: Ensuring precise alignment of components and assemblies.
  • Medical Navigation: Supporting surgical navigation tools and precise instrument positioning.
  • Construction and Surveying: Facilitating the accurate placement and alignment of structures or materials.
  • Quality Assurance: Enhancing inspection, calibration, and metrology processes by quantifying system biases and uncertainties.
