摘要
为降低农村土地地籍测量的误差,提高测量精度,本文结合无人机倾斜摄影测量技术,对农村土地地籍测量方法展开研究,获取地籍测量内业数据,在标定的范围之内,布设倾斜摄影测量控制点,以此为基础,构建无人机倾斜摄影三维地籍测量模型,采用实时动态测量(RTK)联合测定实现地籍测量。通过测试结果表明:对比于传统全球定位系统(GPS)细部地籍测试组、传统遥感地籍测量组,本文设计的无人机倾斜摄影地籍测试组的地籍测量误差相对较小,始终保持在1.3 m以下,说明设计方法能够对测量误差进行有效的控制,对于土地地籍的测定效果较好,测量速度更快,在复杂的土地地籍测量工作中,具有实际的应用价值。
In order to reduce the cadastral error of rural land survey and improve the survey effect,this paper studied the method of rural land cadastral survey combined with unmanned aerial vehicle(UAV)tilt photogrammetry technology.The cadastral office data were obtained and control points were set up for the tilt photogrammetry within the calibrated range.On this basis,a three-dimensional cadastral model was built with of UAV tilt photogrammetry,and the real time kinematic(RTK)joint measurement was applied to realize cadastral measurement.The test results showed that:compared with the traditional global positioning system(GPS)detailed cadastral test group and the traditional remote sensing cadastral survey group,the final cadastral survey error of the UAV tilt photography cadastral test group designed in this paper was relatively small,which was always kept below 1.3 m,which showed that the design method could effectively control the survey error.For the determination of land cadastral,the effect was better,the error was also greatly controlled,and the measurement speed was faster,which has practical application value in complex land cadastral survey.
