DISPLACEMENT ESTIMATION METHOD, DISPLACEMENT ESTIMATION DEVICE |
摘要 |
<p>Disclosed is a displacement estimating method of iteratively estimating displacement using ultrasound signals, and the method includes: transmitting, to a medium, at least one of the ultrasound signals to scan the medium; receiving the ultrasound signal reflected from the scanned medium; calculating a size of a window; calculating a border of the window based on the calculated window size; estimating displacement for each depth of the ultrasound signal, using the window with the calculated border; warping the ultrasound signal based on the estimated displacement; and guiding convergence of the method using the warped ultrasound signal so that a correlation value of the ultrasound signal is larger.</p> |
