The invention relates to the technical field of topographic survey, and discloses a topographic survey device for land planning, the topographic survey device comprises a test part, a receiving assembly and an auxiliary assembly, the test part and the receiving assembly are respectively arranged on two points of topographic survey, and the auxiliary assembly is located above the topographic survey; the auxiliary assembly comprises an unmanned aerial vehicle body, an infrared position sensor and a signal transceiver are installed at the bottom end of the unmanned aerial vehicle body, the test component comprises an adjustable support, a machine head, a double-shaft automatic compensation disc, a shielding cover and a calibration assembly, and the double-shaft automatic compensation disc is arranged at the bottom end of the machine head. The influence range of convection can be reduced by arranging a temporary shielding object, blocking severe convection ventilation, utilizing high-altitude auxiliary distance measurement and controlling measurement in a local space, and in a large-dip-angle state, accumulation of a slant range is reduced through calibration, a geometric strength coefficient between two points is calculated, so that the geometric strength coefficient is increased, and it is indicated that the better the geometric condition is, the better the effect is. And the measurement precision is prevented from being influenced.
本发明涉及地形测量技术领域,公开了一种用于土地规划的地形测量装置,包括测试部件、接收组件和辅助组件,测试部件和接收组件分别设置在地形测量的两点上,辅助组件位于地形测量的上空;辅助组件包括无人机本体,无人机本体的底端安装有红外位置传感器和信号收发器,测试部件包括可调支架、机头、双轴自动补偿盘、屏蔽罩和校准组件,双轴自动补偿盘设置在机头的底端上。本发明通过设置临时遮挡物体,阻隔强对流通风,利用高空辅助进行测距,控制在局部空间内测量可减少对流的影响范围,在大倾角状态下,通过校准减少斜程的积累,计算两点之间的几何强度系数,使其几何强度系数增大,表明几何条件越好,避免测量精度受到影响。
