Multiple-view stereoscopic line-scan imaging

A novel multiple view line-scan imaging technique that can be applied to transmission X-ray imaging as well as reflected light cameras is presented. In either case an area array image sensor is treated as a contiguous set of precisely arranged line-scan devices utilizing a single perspective center. In the case of reflected light the perspective center is the nodal point of a lens whilst in the X-ray case it is the focal spot of an X-ray source. The line-scan images are accumulated in digital memory whilst the object under inspection is linearly translated through the field of view of the camera. In this way a number of perspective images, typically 6 to 16 are produced. The 3D information inherent in the perspective views can be visualized as a smooth object rotation or as a dynamic binocular stereoscopic sequence of view
