ASTM E3124-17

1.1 Purpose-This test method presents metrics and a procedure for measuring, analyzing, and reporting the system latency of an optical tracking system (OTS) that computes the pose of a rigid object.

1.2 Usage-System vendors may use this test method to determine or validate the system latency in their tracking systems. This test method provides a uniform way to measure and report the system latency along with the uncertainty in the system latency. System users may use this test method to verify that the system latency performance is within the user's specific requirements and within the system's rated performance.

1.3 This standard does not measure the display latency of graphical representations of the tracked objects. Display latency is external to the optical tracking system.

1.4 Test Location-The procedures defined in this test method shall be performed in an environment conforming to the manufacturer's rated conditions.

1.5 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
