Outline of Final Research Achievements

We confirmed that the detection distance of the stereo vision three-dimensional sensor can be modulated by tilting the transparent plate placed between the optical lens and the image sensor. Applying this principle function, we have confirmed the distance detection in the range of 10 m even with the single-chip three-dimensional range sensor LSI whose image sensor interval is 8 mm. Moreover, we have confirmed that the distance complementation method that compares several correlation signals can detect the distance of more gradations with only the detection signals with a small number of parallax signals.
