摘　　要：针对当前近景摄影测量技术对影像采集设备以及操作人员专业性要求高的特点,该文在总结前人研究的基础上,提出了一种基于普通数码相机的近景摄影测量技术方法,并将其应用于微区土壤侵蚀监测试验中。通过该方法在人工水冲试验和天然降雨试验前后的土壤侵蚀动态监测得到:与传统土壤侵蚀监测方法相比,采用该方法测得的土壤侵蚀量精度分别可以达到75%和83.11%,单次测量精度最高可达94.33%。通过分析误差来源,结果表明:在一定条件下,可以实现基于普通数码相机的近景摄影测量技术在生产建设项目土壤侵蚀监测中的应用。Aiming at the characteristics of high professional requirements on the image acquisition equipment and the operators of the current close-range photogrammetry technology,a close-range photogrammetry method based on ordinary digital camera was proposed in this paper.This method was applied to the soil erosion dynamic monitoring of artificial water washing test and natural rainfall experiment.Compared with the traditional monitoring method of soil erosion,the soil erosion measure-accuracy of this method could reach 75% and 83.11% respectively;a single measurement precision could be up to94.33%.The analysis results of error source showed that under certain conditions,the application of close-range photogrammetry technology with ordinary digital camera for the soil erosion monitoring in production and construction projects is feasible.This method had reference value for the promotion of innovation of the close-range photogrammetry technology in other fields.
