METHOD FOR DISTANCE ESTIMATION AND APPARATUS FOR THE SAME USING A DISPARITY |
摘要 |
A distance estimating device and method using variance are provided to be used for a safe driving system by reducing an estimated error. A distance estimating method using a stereo vision comprises: a step of selecting a target object and calculating the center of the selected target object using a photographed image(S702,S704); a step of setting a window for the variance estimation of a reference image using the center of the object and brightness distributed intelligence of the image(S706); a step of setting the window of the remaining image not the reference image using the variance mean value of a pixel within the set window(S716); a step of calculating similarity of the pixel within the set window on each image; and a step of estimating the precision variance using the similarity(S718).
