高精度：无人机测绘具有很高的精确度，航拍测绘的实际测量精度达到了亚米级，测图精度一般可以达到1:1000。

环保：无人机测绘具有很高的灵活性和安全性，环境产生的变化对无人机的影响较小。

安全：和传统的测量技术相比无人机测绘具有更加普遍的应用空间，具有更高的灵活性。无人机的利用可以使得地质灾害预测、矿区地质分析、部分危险区域测绘工作开展得更加顺利。

High precision: Drone surveying and mapping has high accuracy, and the actual measurement accuracy of aerial surveying and mapping reaches the sub meter level. The mapping accuracy can generally reach 1:1000.

Environmental protection: Drone mapping has high flexibility and safety, and the impact of environmental changes on drones is relatively small.

Safety: Compared with traditional measurement techniques, drone surveying has a more widespread application space and higher flexibility. The use of drones can make geological disaster prediction, geological analysis of mining areas, and surveying and mapping of some hazardous areas more smooth.

实景建模：无人机使得外业数据采集效率大幅提升，实景模型成果直接展示成果，能够更好地进行地籍测量和管理。地形测量：无人机能进行1:500免像控地形测量，作业效率大概是传统采集方式的5-10倍。

可以根据需求提供DOM、DSM、实景三维模型、数字线划图等成果。城乡规划：能够高效构建实景三维模型，直观地反映地貌与建筑信息，辅助设计人员进行科学规划。

Real scene modeling: UAV greatly improves the efficiency of field data collection, and the real scene model results directly display the results, enabling better Cadastral surveying and management. Terrain measurement: Unmanned aerial vehicles can perform 1:500 imageless terrain measurement, with a work efficiency approximately 5-10 times that of traditional acquisition methods.

We can provide results such as DOM, DSM, realistic 3D models, and digital line drawing according to our needs. Urban and rural planning: capable of efficiently constructing realistic 3D models, intuitively reflecting landscape and architectural information, and assisting designers in scientific planning.

应急快速测量：无人机针对应急灾害地区测绘时可以及时对监测地区进行大范围监测，并快速转化成监测地区的高清图像数据信息。每台无人机的周监测量可以达到2100平方千米左右，监测效率得到大幅提升。

Emergency rapid measurement: When surveying and mapping emergency disaster areas, drones can timely conduct large-scale monitoring of the monitoring area and quickly convert it into high-definition image data information of the monitoring area. The weekly monitoring measurement of each UAV can reach about 2100 Square kilometre, and the monitoring efficiency has been greatly improved.

多角度转换：无人机倾斜摄影可以在实际应用中通过视点移动以及视角转换等，对同一物体的不同角度进行全面采集，实现三维模式的设定。

通过不同的视角变换以及计算机对不动产结构进行重建,整体重建高度还原，可以达到细节百分百的重现。实现此技术可以有效解决传统摄影测绘技术的单一性缺点。

Multi angle conversion: Drone tilt photography can comprehensively capture different angles of the same object through viewpoint movement and angle conversion in practical applications, achieving 3D mode setting.

By transforming different perspectives and using computers to reconstruct the real estate structure, the overall reconstruction is highly restored, achieving a 100% reproduction of details. Implementing this technology can effectively solve the singularity disadvantage of traditional photogrammetry and surveying technology.

高效率：无人机测绘的效率较高，测绘工作中会有许多面积较小的区域，容易受到地理环境的影响，大幅降低工作效率。无人机就能很好地避免这些问题，不容易受地理的影响，获取影像的周期也较短，减轻了工作人员的压力，提升了工作效率。

High efficiency: Unmanned aerial vehicles have high efficiency in surveying and mapping, as there are many small areas in the surveying work that are easily affected by the geographical environment, greatly reducing work efficiency. Unmanned aerial vehicles can effectively avoid these problems, are not easily affected by geography, and have a shorter period of acquiring images, reducing the pressure on staff and improving work efficiency.

目前，除了倾斜摄影和小面积测绘会采用多旋翼，一般工程测绘主要采用固定翼无人机或垂直起降无人机。采购方需根据需求选配无人机飞行平台（多旋翼/固定翼），测绘测量设备一般比较贵重，建议选择知名厂家产品。小面积推荐选配多旋翼无人机，大面积推荐固定翼无人机，当然也得看其负载能力的大小，具体情况视情况而定。

At present, in addition to tilt photography and small area surveying and mapping, multi rotors will be used, and general engineering surveying and mapping mainly uses fixed wing UAVs or VTOL UAVs. The purchaser needs to select and equip unmanned aerial vehicle flight platforms (multi rotor/fixed wing) according to their needs. Surveying and measuring equipment is generally expensive, and it is recommended to choose products from well-known manufacturers. It is recommended to choose multi rotor drones for small areas, and fixed wing drones for large areas. Of course, it also depends on the load capacity, and the specific situation depends on the situation.
