Designation:E291914Standard Test Method forEvaluating the Performance of Systems that Measure Static,Six Degrees of Freedom(6DOF),Pose1This standard is issued under the fixed designation E2919;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 PurposeIn this test method,metrics and proceduresfor collecting and analyzing data to determine the performanceof a pose measurement system in computing the pose(positionand orientation)of a rigid object are provided.1.2 This test method applies to the situation in which boththe object and the pose measurement system are static withrespect to each other when measurements are performed.Vendors may use this test method to establish the performancelimits for their six degrees of freedom(6DOF)pose measure-ment systems.The vendor may use the procedures described in9.2 to generate the test statistics,then apply an appropriatemargin or scaling factor as desired to generate the performancespecifications.This test method also provides a uniform way toreport the relative or absolute pose measurement capability ofthe system,or both,making it possible to compare theperformance of different systems.1.3 Test LocationThe methodology defined in this testmethod shall be performed in a facility in which the environ-mental conditions are within the pose measurement systemsrated conditions and meet the users requirements.1.4 UnitsThe values stated in SI units are to be regardedas the standard.No other units of measurement are included inthis standard.1.5 This standard does not purport to address all of thesafety concerns,if any,associated with its use.It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.Referenced Documents2.1 ASTM Standards:2E456 Terminology Relating to Quality and StatisticsE2544 Terminology for Three-Dimensional(3D)ImagingSystems2.2 ASME Standard:3ASME B89.4.19 Performance Evaluation of Laser-BasedSpherical Coordinate Measurement Systems2.3 ISO/IEC Standards:4JCGM 200:2012 International Vocabulary of MetrologyBasic and General Concepts andAssociated Terms(VIM),3rd editionJCGM 100:2008 Evaluation of Measurement DataGuideto the Expression of Uncertainty in Measurement(GUM)IEC60050-300:2001 InternationalElectrotechnicalVocabularyElectrical and Electronic Measurements andMeasuring Instruments3.Terminology3.1 Definitions from Other Standards:3.1.1 calibration,noperation that,under specifiedconditions,in a first step,establishes a relation between thequantity values with measurement uncertainties provided bymeasurement standards and corresponding indications withassociated measurement uncertainties and,in a second step,uses this information to establish a relation for obtaining ameasurement result from an indication.JCGM 200:20123.1.1.1 Discussion(1)A calibration may be expressed by a statement,calibra-tion function,calibration diagram,calibration curve,or cali-bration table.In some cases,it may consist of an additive ormultiplicative correction of the indication with associatedmeasurement uncertainty.1This test method is under the jurisdiction of ASTM Committee E57 on 3DImaging Systems and is the direct responsibility of Subcommittee E57.02 on TestMethods.Current edition approved July 1,2014.Published August 2014.Originallyapproved in 2013.Last previous edition approved in 2013 as E2919-13.DOI:10.1520/E2919-14.2For referenced ASTM standards,visit the ASTM website,www.astm.org,orcontact ASTM Customer Service at serviceastm.org.For Annual Book of ASTMStandards volume information,refer to the standards Document Summary page onthe ASTM website.3Available from American Society of Mechanical Engineers(ASME),ASMEInternational Headquarters,Three Park Ave.,New York,NY 10016-5990,http:/www.asme.org.4Available from American National Standards Institute(ANSI),25 W.43rd St.,4th Floor,New York,NY 10036,http:/www.ansi.org.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1(2)Calibration should not be confused with either adjust-ment of a measuring system,often mistakenly called“self-calibration,”or verification of calibration.(3)Often,the first step alone in 3.1.1 is perceived as beingcalibration.3.1.2 maximum permissible measurement error,maximumpermissible error,and limit of error,nextreme value ofmeasurement error,with respect to a known reference quantityvalue,permitted by specifications or regulations for a givenmeasurement,measuring instrument,or measuring system.JCGM 200:20123.1.2.1 Discussion(1)Usually,the terms“maximum permissible errors”or“limits of error”are used when there are two extreme values.(2)The term“tolerance”should not be used to design
