Aerospace Instrument-Making Annotation << Back ON MEASUREMENTS PAIRED GAUGES S.N. Guzevich Тhe article considers the reasons for the inaccurate determination of the position and the linear dimensions of objects by using the pair of stereoscopic measuring instruments and methods that are associated with the construction of geometric models. The description of the representations of objects in the steam transverse projective coordinate system. This approach significantly simplified and changed geometrical relations for the description of the main analytical dependences of otstoyali and the size of the object. No need to use angular transcendental functions for the evaluation of otstoyali objects. Derived rule for the transformation of the representations of the parties to the measuring object pair, which is expressed by the ratio of the total relevance for each point of observation on the object. The concepts of reliability and uncertainty display linear dimensions of the object. Key words: stereoscopic meter, observation point, the linear size of the object, steam projective coordinate system, the rule of transformation, coefficient general relevance, reliability, uncertainty.
