    摘要: To measure a hollow three-dimensional object without contact, this object being translucent or transparent vis-á-vis a visible light, an image of the object is acquired by single-view backlit shadowgraphy, along a viewing axis, by observing this object with visible light, this image comprising at least one luminous line, an equation is established that connects at least one optogeometric parameter of the object to at least one geometric parameter of the luminous line, this geometric parameter is determined, and the optogeometric parameter is determined by means of the equation and the geometric parameter thus determined.
