Video rasterstereography : a method for on-line measurement of body surfaces

Rasterstereography (using a projected grid) is a method for three-dimensional measurement of body surfaces. Up to now precision measurements were only possible using film recording, because video cameras were too low in resolution. Recently, high resolution solid state video cameras became available. Thus, rasterstereography with on-line image processing is enabled, avoiding time consuming and cumbersome film development and scanning. In this paper the hardware design of a real video rasterstereographic system for medical applications (measurement of the human back surface).
