ScopeThis SAE Recommended Practice is intended to provide guidelines for the identification of sub

5、jectsused in dynamic tests. It establishes recommendations for location and description of target areas on testsubjects or test devices, as well as recommendations for photographic calibration and timing.2. ReferencesThere are no referenced publications specified herein.3. Target DescriptionTarget s

6、ize should be at least 1/100 of the field width covered by the camera, and ofcontrasting colors or contrast with background. Yellow and black or white and black are preferable. The centerof the target must be easily discernible.4. Target MountingTarget should be mounted or painted on the test fixtur

7、e and to the subjects skin or firmlyattached to tightly-fitting clothing which minimizes target movement with respect to the subject.5. Target Locations and Body DimensionsIt is suggested that targets be located on test subjects in auniform manner. Figure 1, Figure 2, and Figure 3 show two methods t

8、hat can be used for locating the testsubjects targets and a:a. seating-fixture reference for test devices (Figure 1).b. anatomical landmarks for human volunteers and cadavers (Figure 2).c. minimum external body dimensions for human volunteers and cadavers (Figure 3).If A-P photometrics are used, add

9、itional targets should be located on the mid-curve.6. High-Speed Camera DescriptionLens focal length, camera make and model, and a sketch showingdimensions from camera to subject should be included with each test series. An alternate method may beused wherein the camera location can be determined fr

A ground-mounted target or targets is often of greatbenefit.8. Photograph Timing DescriptionAn appropriate desc
