摘要：When conducting depth estimation using image sensing it is necessary for the system to be able to deal with a large amount of comparisons and operations; therefore, achieving high-speed performance is a challenge. In order to solve this problem, we propose a depth estimation system that uses a smart image sensor that has an in-focus judgment function with multiple-focus images. This judgment function is based on the “depth from focus” (DFF) technique, which has the following advantages: 1) a simple algorithm, 2) a single camera, and 3) it is more accurate in the broad-depth estimation area. Furthermore, we propose an interpolation method for getting depth values in textureless regions that cannot be obtained using the judgment function of the smart image sensor. We evaluated our proposed method using computer simulation and we show some experimental results obtained using the prototype chip.
