Приведены краткие сведения о системе, ее устройстве, принципах измерения дальности и построения карт глубин с ее помощью. В качестве материала для исследования взяты восемь видеофайлов, которые получены в результате проведения экспериментальных исследований в большой аэрозольной камере при использовании активно-импульсной телевизионной измерительной системы в режиме многозонного измерения дальности и многозонного измерения дальности с модуляцией. Предложен метод вычитания коэффициентов, обеспечивающий устранение расхождения значений относительной яркости на нормированной карте глубин между темными и светлыми объектами, находящимися на одном расстоянии от системы. Метод экспериментально апробирован. Выполнено сравнение предложенного метода и метода вычитания темнового кадра по критерию минимизации среднеквадратического отклонения измеренной глубины между темными и светлыми объектами. В результате применения обоих методов достигнуто уменьшение среднеквадратического отклонения от 1,3 до 20 раз в зависимости от примененного метода минимизации и метода измерения дальности, используемого в системе. Метод вычитания коэффициентов может быть использован только в процессе постобработки, однако он показывает лучшие результаты, по сравнению с методом вычитания темнового кадра, который может быть использован в режиме реального времени.</p></abstract><trans-abstract xml:lang="en"><p>The influence of the reflectivity of objects on the accuracy of constructing a normalized depth map of space using an active-pulse television measuring system is considered. Brief information about the system, its structure, principles of measuring range and constructing depth maps with its help is given. Eight video files obtained as a result of experimental studies in a large aerosol chamber using an active-pulse television measuring system in the multi-zone range measurement mode and multi-zone range measurement with modulation are taken as material for the study. A method for subtracting coefficients is proposed, which ensures the elimination of the discrepancy in the relative brightness values on the normalized depth map between dark and light objects located at the same distance from the system. The method is experimentally tested. A comparison of the proposed method and the method of subtracting a dark frame is performed according to the criterion of minimizing the root-mean-square deviation of the depth measurement between dark and light objects. As a result of applying both methods, the mean square deviation was reduced by 1.3 to20 times, depending on the minimization method and the range measurement method used in the system. The coefficient subtraction method can only be used in post-processing, but it shows better results than the dark frame subtraction method, which can be used in real time.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>отражательная способность объектов</kwd><kwd>активно-импульсная телевизионная измерительная система</kwd><kwd>нормированная карта глубин</kwd><kwd>метод вычитания коэффициентов</kwd><kwd>метод вычитания темнового кадра</kwd></kwd-group><kwd-group xml:lang="en"><kwd>reflectivity of objects</kwd><kwd>active pulse television measuring system</kwd><kwd>normalized depth map</kwd><kwd>coefficient subtraction method</kwd><kwd>dark frame subtraction method</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование выполнено за счет гранта Российского научного фонда № 21-79-10200 в ТУСУР.</funding-statement><funding-statement xml:lang="en">This work was supported by the grant of the Russian Science Foundation № 21-79-10200 to TUSUR.</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Gimeno J. et al.
