摘要
在建筑物之中由于阳台结构比较复杂,存在弧面,导致计算结果与实际数值偏差较大,由此开展基于倾斜摄影测量单体化模型的建筑阳台面积自动化计算研究。通过建立基于倾斜摄影测量构建建筑阳台三角网模型,区分阳台弧面和平面,然后创建建筑阳台绘制基元视景,最后利用基于最大矩形装箱算法完成阳台拼接面积的自动求取。通过实验证明,此计算方法能对建筑阳台进行自动化计算,并且计算结果满足精度要求,在实际应用中有一定的参考价值。
The balcony structure in the building is complicated and there are curved surfaces,which makes the calculation result deviate from the actual value.Therefore,the automatic calculation of the building balcony area based on the tilt photogrammetric unit model is carried out.By establishing a triangular network model of building balcony based on oblique photogrammetry,distinguishing balcony arcs and planes,a primitive visual scene of building balcony drawing is created,and finally the largest rectangle packing algorithm is used to complete the automatic calculation of the splicing area.Experiments prove that this calculation method can automatically calculate building balconies in practical applications,and the results can meet accuracy requirement thus is worthy of reference.
