1.1 Purpose—This test method presents metrics and procedures for measuring, analyzing, and reporting the relative pose error of optical tracking systems that compute the pose (that is, position and orientation) of a rigid object while the object is moving.

1.2 Usage—System vendors may use this test method to determine the performance of their Six Degrees of Freedom (6 DOF) optical tracking system which measures pose. This test method also provides a uniform way to report the measurement errors and measurement capability of the system. System users may use this test method to verify that the system’s performance is within the user’s specific requirements and within the system’s rated performance.

1.3 Test Location—The procedures defined in this standard shall be performed in a facility in which the environmental conditions are within the optical tracking system’s rated conditions.

1.4 Test Volume—This standard shall be used for testing an optical tracking system working volumes of 3000 mm long by 2000 mm wide by 2000 mm high, 6000 mm long by 4000 mm wide by 2000 mm high, or 12 000 mm long by 8000 mm wide by 2000 mm high.

1.5 Units—The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

5.1 Optical tracking systems are used in a wide range of fields including: video gaming, filming, neuroscience, biomechanics, flight/medical/industrial training, simulation, robotics, and automotive applications.

5.2 This standard provides a common set of metrics and a test procedure for evaluating the performance of optical tracking systems and may help to drive improvements and innovations of optical tracking systems.

5.3 Potential users often have difficulty comparing optical tracking systems because of the lack of standard performance metrics and test methods, and therefore must rely on the claims of a vendor regarding the system’s performance, capabilities, and suitability for a particular application. This standard makes it possible for a user to assess and compare the performance of candidate optical tracking systems, and allows the user to determine if the measured performance results are within the specifications with regard to the application requirements.
