| titleOfInvention | A kind of 3D shape automatic division method based on Mean Shift |
| abstract | The invention provides a kind of based on Mean? the 3D shape automatic division method of Shift, the local feature of each 3D shape grid is obtained by the distance on characterization summit, obtain the centre coordinate of its grid according to the apex coordinate of 3D shape grid, obtain four dimensional feature space combined; Do you adopt Mean? Shift algorithm carries out cluster calculation in aforementioned four dimensional feature space, obtains the unique point that cluster numbers and each cluster comprise; K arest neighbors sorting technique is adopted to carry out decision space modeling to cluster calculation result, local correction segmentation result; Adopt visualization technique that the segmentation result after local correction is carried out coloring treatment according to the mode of cluster attribute flags color, adopt the fiducial error of Princeton segmentation this dividing method of benchmark under difference is measured, thus carry out quantitatively evaluating.The present invention has that segmentation precision is high, automaticity is high, be suitable for the wide feature of 3D shape scope. |
