ASTM E2566-17A - Standard Test Method for Evaluating Response Robot Sensing: Visual Acuity

1.1 The purpose of this test method is to specify the apparatuses, procedures, and performance metrics necessary to quantitatively measure a robot’s visual acuity as displayed to a remote operator or vision algorithm. The primary performance metric for this test method shall be a robot’s possession of such a capability with a specified statistical significance level.

1.2 Secondary performance metrics are the robot’s field of view and aspect ratio.

1.3 This test method can also be used to measure the operator proficiency in performing the specified task. The corresponding performance metric may be the number of completed task repetitions per minute over an assigned time period ranging from 10 to 30 minutes.

1.4 This test method is a part of the sensing suite of response robot test methods, but this test method is stand-alone and complete. This test method applies to systems operated remotely from a standoff distance appropriate for the intended mission. The system includes a remote operator in control of all functionality and any assistive features or autonomous behaviors that improve the effectiveness or efficiency of the overall system.

1.5 The apparatus, specified in Section 6, can only test a limited range of a robot’s capabilities. When the robot has been tested through the limit or limits of the apparatus, a note shall be associated with the results indicating that the robot’s actual capability may be outside of the limit or limits imposed by the test apparatus. For example, the robot could exceed the capabilities of the printing process used to create the charts used in the apparatus.

1.6 Performing Location—This test method may be performed anywhere the specified apparatuses and environmental conditions can be implemented.

1.7 Units—The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the standard. Both units are referenced to facilitate acquisition of materials internationally and minimize fabrication costs.

1.8 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.

1.9 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.
