This document defines performance criteria for an optical data channel used in impact tests on road vehicles, when numerical time and space data are taken from images to analyse impact test results.<\/p>\n
The objective of this document is to facilitate comparison between results obtained by different laboratories by specifying minimum quality criteria.<\/p>\n
Annexes A, B, C and D present a method of measuring several indices like quality parameters of sub processes of the optical data channel, using a calibration target, reference distances and analysis systems.<\/p>\n
