Visorama consists of the following elements:
The stereoscope is the component used to observe the images. It consist of an optical system linked to two CRT video monitors.
The support base is the mechanism where the stereoscope is linked. It consists of a rotatable head and a body. The head makes two axial movements: a panoramic movement (through the vertical axis) and a longitudinal movement (through the horizontal axis). The movement is concentrated in the nodal point of the stereoscope's optical system.
The control unity consists of sensors and device controls. This component performs the link between the physical equipment and the image generation system. It collects the input parameters and transmit them to the image generation system. These parameters includes the rotation and elevation angle, as well as the zoom in/out factor and the bottom set ups of the control panel.
The image generating system produces the images that are exhibited through the stereoscope. These images relate to a window of the scene represented in the panoramic image, which is determined through the parameters given from the control unity. The image generating system involves the following subsystems: video; graphics and storage.
