文中基于单幅温度图像,利用单元分解表示法重构组合体三维模型。首先采用以极限腐蚀为标记集的SKIZ对组合体二值图像进行分割,再用内点角点分类法和SKIZ角点分类法相结合将检测到的角点和关键点分类,然后利用同类角点和关键点坐标确定构成组合体的各体素在温度图像中的区域,得到独立的标准体素,接着根据单独标准体素所具有的几何特性对它们所属类别进行识别,再利用提取的关键参数对其进行重构,最后将简单体素三维模型进行叠加,得到目标组合体的三维模型。
The combined unit is reconstructed based on single infrared image as follows:① The combined unit is segmented to standard unit by SKIZ. ② Through the combination of inner point classification and SKIZ classification,the comers and key points in the edge features are classified to belong to the standard units segmented from the combined unit. ③ The corners and key points belonging to the same unit restrict the area of the standard unit in the thermal image, and all the standard units segmented from the combined unit are reconstructed by using the reconstruction algorithm of independent unit. ④ The 3D model of combined unit is obtained by using the algorithm of intersection,union and difference of 3D models of standard units reconstructed.
