摘　　要：针对观测环境恶劣且纹理信息不丰富和特征不明显的风沙地物,该文以徕卡ScanStation C10三维激光扫描仪为例,提出了一套适用于风沙领域的观测方案,并梳理室内外工作流程。详细阐述观测方案中控制点、设站、活动标靶等空间布设要求及拼接方式,总结技术难点并提出解决方法。通过与传统测量设备全站仪进行比对,检验该方法的可靠性。基于风沙地貌、风沙灾害和防沙措施效益评估等研究方向的实践与应用表明,该方案不仅确保测量精度,提高野外工作效率,还可降低后期数据处理的工作量和难度。In view of the terrible research condition, lack texture information and not obvious characteristic, this paper took Leiea C10 3D laser scanner for an example and proposed an observation scheme applied in the Aeolian field, then the indoor and outdoor working process were introduced. The spatial ar- rangement of reference control point, station and active target and the model of combination in the Aeolian environment were discussed. The technical difficulties were summarized and its solutions were put for- ward. The reliability of this method was tested by comparing with the traditional measuring equip- ment. The results showed that the proposed plan could guarantee the accuracy of measurement, improve the efficient of field work and greatly reduce the difficulty of data process.
