Describes a hardware system for generating a real-time stereoscopic image sequence by means of a dense field of 1D disparity vectors, allowing intermediate perspectives to be produced. The concept of a virtual camera is illustrated and the need for disparity estimation at the TV transmitter as well as at the receiver is noted. The possibility of 3D video conferencing is stated. An algorithm and the construction of a hardware system for disparity estimation are reported. The hardware is based on a Texas Instruments TMS320C44 digital signal processor. Uses for remote control of industrial robots are suggested and a diagram of a local block matching board is presented.
