摘   要 ：采用目前方法生成建筑結構平面圖空間數據時，無法獲取建筑結構對象特征，存在還原性差、VRI 值低和完全度低的問題， 因此提出基于對象特征的建筑結構平面圖空間數據自動生成方法。采用射線跟蹤算法實現目標模型到圖像平面的幾何映射，在電磁散射模型的基礎上獲得后向散射圖 。采用主成分分析方法獲取后向散射圖中的建筑結構對象特征，根據提取的特征通過卷積運算生成建筑結構平面圖空間數據 。試驗結果表明，所提方法的還原性好 、VRI 值高、完全度高。

Abstract: When the current method is used to generate spatial data of building structure plan, the object characteristics of building structure can not be obtained, and there are some problems such as poor reducibility, low VRI value and low completeness. Therefore, an automatic generation method of spatial data of building structure plan based on object characteristics is proposed. The ray tracing algorithm is used to realize the geometric mapping from the target model to the image plane, and the backscatter map is obtained based on the electromagnetic scattering model. The principal component analysis method is used to obtain the features of the building structure object in the backscatter map. According to the extracted features, the spatial data of the building structure plan is generated by convolution operation. The experimental results show that the proposed method has good reducibility, high VRI value and high completeness.

Keywords: building structure; floor plan; spatial data generation; ray tracing algorithm; object characteristics
