| 摘 要： | 目的]研究枣树坐标参数的数字近景摄影测量。方法]应用Lensphoto多基线数字近景摄影测量系统,对8年生枣树的三维坐标参数进行了近景摄影测量,并将摄影测量数据与全站仪测量数据进行了比较。结果]对于较多小细枝的枣树,X、Y、Z坐标的绝对误差分别为0～0.014、0～0.018、0～0.004 m,相对误差均低于0.145%。摄影测量坐标值和真值配对数据的显著性检验和线性回归分析表明,该测量方法能够获得真实可靠的数据,做到精准监测,满足虚拟植物生长模拟的坐标数据测定要求。结论]为虚拟植物模拟的树木生长观测提供了理论依据。

| Abstract: | Objective] The aim was to explore the measurement of coordinate parameter by multi-baseline digital close-range photogrammetry system.Method] The 3-dimensional coordinate of 8-year-old Jujube was measured by using Lensphoto multi-baseline digital close-range photogrammetry system,and through comparing with measured data of total station,the error and accuracy of photogrammetry data were analyzed.Result] The absolute error of X,Y and Z coordinate was 0-0.014,0-0.018 and 0-0.004 m respectively,and the rela... |
