三维激光扫描技术在异形结构表面积测算中的应用研究

Application and research of three-dimensional laser scanning technology in the superficial area measurement and calculation of irregular structures

表面积测算在建筑、林业和医学中都有着重要应用,传统的目标实体表面积测算工具常以表面积测定仪、全站仪等为主,但是往往受限于测量仪器的精度和测量过程的复杂性,无法满足对异形结构表面积的精确测算需求。文章应用三维激光扫描技术对不规则实体表面积测算理论和技术方法进行研究,并以某异形雕塑为工程案例进行验证。研究结果表明,该方法具有无接触、自动测量且精度和作业效率高等优势,对于推动该领域的发展具有重要意义。

Surface area estimation has important applications in architecture,forestry and medicine.The traditional surface area estimation of target entity is usually based on surface area meter and total station,etc.,but it is often limited by the accuracy of measuring instruments and the complexity of measuring process,which cannot meet the demand for accurate surface area measurement of special-shaped structures.In this paper,three-dimensional laser scanning technology is used to study the theory and technical method of measuring the irregular solid surface area,and a special shaped sculpture is used as an engineering case to verify it.The research results show that the method has the advantages of non-contact,automatic measurement,high precision and working efficiency,which is of great significance for promoting the development of this field.
