This International Standard defines performance criteria for an optical data channel used in impact tests on road vehicles, when numerical time and space data are taken from the images to analyse impact test results.
The requirements are to facilitate comparison between results obtained by different laboratories.
The annex gives a method of measuring the distortion index as a quality parameter of the optical data channel using a standard target, and, as an alternative, an indirect method.
This International Standard complements ISO 6487 which covers non-optical instrumentation used in impact tests on road vehicles.
