摘要:
提出了一种基于投影轮廓的检索算法.首先通过法面积计算,统计仿射坐标系下算术法面积,进行比较得到极大算术法面积和对应的向量,从而确定投射方向.将3D模型以投射方向为参考进行变换,然后向3个投射平面投射生成轮廓.这样2个模型的比较就可以转化成2D图线的比较,降低了模型比较的计算量,提高了模型检索的速度.结果表明,该算法有望在未来的虚拟现实、工业设计、动画制作、机械设计、CAD、影视等领域得到广泛应用.
Abstract:
Based on projective contour a retrieval algorithm is proposed. First, the statistical arithmetical area is deduced by calculating the normal area and the maximum one is achieved, then the corresponding vector is gained and the projection orientation is determined. Secondly, the 3D model is transformed based on the projection orientation. So projection can be accomplished and three contours are achieved. Integrated similarity can then be calculated by comparing waves according to three contours. 3D models are transformed into 2D, which makes the comparability simple by decreasing the complexity of calculation. The results indicate that this method is promising in many fields, such as virtual reality, industrial design, animation, mechanical design and filming.
