| Abstract: | The precise image edge location was very important for image measurement.Therefore,the sub-pixel algorithm in edge precise positioning was widely researched.Through ideal light bar method,some representative sub-pixel algorithm were compared for the capability of positioning circular arc edge.The experiment showed that the center-of-gravity method had the best result for positioning the edge of a symmetrical arc. |
