【摘要】：提出一种面向三维机械零件模型检索的手绘草图查询接口。首先,利用模型的法向量最大分布方向来辅助主成分分析(PCA)算法对三维模型的空间姿态进行旋转归一,使得模型投影视图和用户手绘草图的视角一致;然后采用一种二维图像相似性比较算法衡量用户草图和模型投影视图之间的相似性,从而得到与用户提交的查询草图相似的三维零件模型。实验结果表明所提出的手绘草图查询接口能够让用户快速地表达查询意图,且具有较高的检索准确性。
[Abstract]:This paper presents a query interface of hand-drawn sketches for 3D mechanical part model retrieval. Firstly, the maximum distribution direction of the normal vector of the model is used to assist the principal component analysis (PCA) algorithm to rotate and normalize the spatial attitude of the 3D model, which makes the projection view of the model consistent with the user's hand-drawn sketch view. Then, a two-dimensional image similarity comparison algorithm is used to measure the similarity between the user sketch and the model projection view, and a three-dimensional part model similar to the query sketch submitted by the user is obtained. The experimental results show that the proposed hand-sketched query interface can express the query intention quickly and has high retrieval accuracy.
