Показано, что абсолютная ошибка пропорциональна длительности импульса tL. Для трапециеобразной формы импульса, являющейся разумной аппроксимацией реальной формы импульса, получены аналитическая оценка экстремальной ошибки и расстояние, при котором она реализуется. Максимальная ошибка в дальности, полученная в расчетах с трапециеобразными импульсами, соответствует крайне асимметричным импульсам и составляет чуть более 10 % пространственной длины импульса tLc, где с - скорость света. Симметричные импульсы дают ошибку из-за непрямоугольности импульса, в ~2 раза меньшую. Поскольку трапециеобразная форма способна качественно воспроизвести форму практически любого реального импульса, вероятно, модель трапециеобразного импульса дает оценку максимально возможной ошибки. </p></abstract><trans-abstract xml:lang="en"><p>The accuracy analysis of distance determination by range-intensity correlation methods in the case of arbitrary pulse shape is performed. It is shown that the absolute error is proportional to the pulse duration tL. For the trapezoidal shape of the pulse, which is a reasonable approximation of the real pulse shape, analytical estimates of the extreme error and range at which it is realized are obtained. For the model of trapezoidal pulses, maximum of the distance absolute error corresponds to extremely asymmetric pulses and is 10% of the spatial pulse length tLc, where c is the light velocity. At the same time, symmetrical pulses produce an error due to the pulse non-rectangularity approximately two times smaller. Since the trapezoidal shape is able to reproduce qualitatively the shape of almost any real pulse, it is very likely that the trapezoidal pulse model estimates the maximum possible error. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>активно-импульсная система видения</kwd><kwd>непрямоугольная форма импульса подсветки</kwd><kwd>метод корреляции расстояние-интенсивность</kwd><kwd>расстояние до объекта</kwd><kwd>active-pulse vision system</kwd><kwd>non-rectangular shape of the illumination pulse</kwd><kwd>range-intensity correlation method</kwd><kwd>distance to the object</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">L.
