Abstract A new system that combines multi-vision system and synthetic aperture system is proposed to improve the measurement of small-scale or longer-range object. In the system, the parallax information is recorded by multi-vision system, meanwhile, a higher optical resolution image is obtained by synthesizing several optical apertures of multi-vision system to increase the effective aperture. By fusing the higher resolution image into the parallax images, we can acquire higher resolution images with parallax information from which the measurement can be improved greatly. As an example, a trinocular vision system improved by synthetic aperture has been studied experimentally. Results show that the method can improve the resolution in detection about two times and perform more accurate measurement than traditional multi-vision system.
