Description
Существующие методы контрол освещенности кадров стереопары основаны на визуальном наблюдении ркости экрана из центров зон стереовидени . Недостаток этих методов заключаетс в том, что наблюдатель , сместивщись из центров зон стереовидени , неправильно оценивает равенство ркостей левого и правого изображений.Existing methods for controlling the illumination of stereopair frames are based on visual observation of screen brightness from the centers of stereovision zones. The disadvantage of these methods lies in the fact that the observer, having shifted from the centers of the stereovision zones, incorrectly estimates the equality of the left and right images.
Предлагаемое устройство объективно оценивает световые потоки. Это достигаетс применением в качестве приемников излучений фотоэлементов .The proposed device objectively evaluates the light fluxes. This is achieved by using photocells as radiation receivers.
На фиг. 1 изображена принципиальна схема размещени фотоэлементов за гран ми призм стереонасадки; на фиг. 2 - размещение фотоэлементов за двум трубками-светопроводами; на фиг. 3 - схема включени фотоэлементов в предлагаемых устройствах.FIG. 1 is a schematic diagram of the arrangement of photocells beyond the edges of the stereo nozzle prisms; in fig. 2 - placement of photocells behind two light guide tubes; in fig. 3 is a diagram of the inclusion of photocells in the proposed devices.
За гран ми призм 1-1 (фиг. 1) двухобъективной насадки стереопроектора устанавливаютс фотоэлементы 2-2, включенные с гальванометром 3 по дифференциальной схеме (фиг. 3). Дл создани достаточного уровн освещенности на поверхност х фотоэлементов грани лризм имеют необходимую степень пропускани светового потока. Видоизменение формы выполнени предлагаемого устройства состоит в том, что фотоэлементы 2-2 размещаютс за трубками 4-4, ограничивающими световые потоки, отраженные от соответствующих кадров стереопары 5-5 (фиг- 2) в фильмовом канале 6 со стороны источников света. Неодинаковое освещение кадров стереопары определ емс по гальванометру 3 с нулевой щкалой по середине.Beyond the edges of prisms 1-1 (Fig. 1) of a two-lens stereoprojector attachment, photocells 2-2 are mounted, connected with a galvanometer 3 according to a differential circuit (Fig. 3). In order to create a sufficient level of illumination on the surface of photovoltaic cells, the lenrism has the necessary degree of transmission of the luminous flux. A modification of the form of implementation of the proposed device is that photo cells 2-2 are placed behind the tubes 4-4, limiting the light fluxes reflected from the corresponding frames of the stereo pair 5-5 (Fig-2) in the film channel 6 from the side of the light sources. The unequal lighting of the stereopair frames is determined by a galvanometer 3 with a zero scale in the middle.
