【摘要】：提出一種面向三維機械零件模型檢索的手繪草圖查詢接口。首先,利用模型的法向量最大分布方向來輔助主成分分析(PCA)算法對三維模型的空間姿態(tài)進行旋轉(zhuǎn)歸一,使得模型投影視圖和用戶手繪草圖的視角一致;然后采用一種二維圖像相似性比較算法衡量用戶草圖和模型投影視圖之間的相似性,從而得到與用戶提交的查詢草圖相似的三維零件模型。實驗結果表明所提出的手繪草圖查詢接口能夠讓用戶快速地表達查詢意圖,且具有較高的檢索準確性。
[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.
