PROBLEM TO BE SOLVED: To solve such a problem that a high-density disparity value image to be derived by a ranging method using an SGM (Semi-Global Matching) can derive a disparity value even in a case of an object with weak texture, however, when there is a neighboring object with strong texture, it is difficult to derive an accurate disparity value due to harmful effects on a disparity value of the object with weak texture.SOLUTION: A spatial filter is applied to a disparity value, so that, even when there is a neighboring object with strong texture, the disparity deriving apparatus can make it less susceptible that a disparity value of an object with weak texture is subjected to harmful effects, so as to derive farther accurate disparity value. |
