摘要
表面积估计在建筑、林业和城市建设中具有重要意义,传统的不规则实体表面积测算常以表面积测定仪、全站仪等为主。随着科技的发展,应用计算机视觉建立目标物实景三维模型,再进行表面积测算逐渐在测绘领域得到应用。文章以塑石雕塑表面积测算为工程案例,基于无人机贴近摄影测量技术内外业获取目标物三维点集,应用Geomagic软件建立雕塑三模模型,测算其表面积。与表面积测量仪测算结果对比,贴近摄影测量技术进行表面积统计结果较为准确,可以对城市异形结构装饰美化工程中表面积测算提供参考。
Surface area estimation is of great significance in construction,forestry and urban construction.The traditional surface area measurement of irregular entities is often based on surface area meter,total station,etc.With the development of technology,the application of computer vision to establish a realistic three-dimensional model of the target object and then calculate the surface area is gradually being applied in the field of surveying and mapping.Taking the calculation of the surface area of plastic stone sculpture as an engineering case,based on the UAV close to the photogrammetry technology to obtain the three-dimensional point set of the target,the paper uses Geomagic software to establish a sculpture the third mock examination model and calculate its surface area.Compared with the calculation results of surface area measuring instruments,the results of surface area statistics using photogrammetry technology are more accurate,and can provide reference for surface area calculation in urban irregular structure decoration and beautification projects.
