高精度：無人機(jī)測繪具有很高的精確度，航拍測繪的實際測量精度達(dá)到了亞米級，測圖精度一般可以達(dá)到1:1000。
環(huán)保：無人機(jī)測繪具有很高的靈活性和安全性，環(huán)境產(chǎn)生的變化對無人機(jī)的影響較小。
安全：和傳統(tǒng)的測量技術(shù)相比無人機(jī)測繪具有更加普遍的應(yīng)用空間，具有更高的靈活性。無人機(jī)的利用可以使得地質(zhì)災(zāi)害預(yù)測、礦區(qū)地質(zhì)分析、部分危險區(qū)域測繪工作開展得更加順利。
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.
實景建模：無人機(jī)使得外業(yè)數(shù)據(jù)采集效率大幅提升，實景模型成果直接展示成果，能夠更好地進(jìn)行地籍測量和管理。地形測量：無人機(jī)能進(jìn)行1:500免像控地形測量，作業(yè)效率大概是傳統(tǒng)采集方式的5-10倍。
可以根據(jù)需求提供DOM、DSM、實景三維模型、數(shù)字線劃圖等成果。城鄉(xiāng)規(guī)劃：能夠高效構(gòu)建實景三維模型，直觀地反映地貌與建筑信息，輔助設(shè)計人員進(jìn)行科學(xué)規(guī)劃。
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.
應(yīng)急快速測量：無人機(jī)針對應(yīng)急災(zāi)害地區(qū)測繪時可以及時對監(jiān)測地區(qū)進(jìn)行大范圍監(jiān)測，并快速轉(zhuǎn)化成監(jiān)測地區(qū)的高清圖像數(shù)據(jù)信息。每臺無人機(jī)的周監(jiān)測量可以達(dá)到2100平方千米左右，監(jiān)測效率得到大幅提升。
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.
多角度轉(zhuǎn)換：無人機(jī)傾斜攝影可以在實際應(yīng)用中通過視點移動以及視角轉(zhuǎn)換等，對同一物體的不同角度進(jìn)行全面采集，實現(xiàn)三維模式的設(shè)定。
通過不同的視角變換以及計算機(jī)對不動產(chǎn)結(jié)構(gòu)進(jìn)行重建,整體重建高度還原，可以達(dá)到細(xì)節(jié)百分百的重現(xiàn)。實現(xiàn)此技術(shù)可以有效解決傳統(tǒng)攝影測繪技術(shù)的單一性缺點。
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：無人機(jī)測繪的效率較高，測繪工作中會有許多面積較小的區(qū)域，容易受到地理環(huán)境的影響，大幅降低工作效率。無人機(jī)就能很好地避免這些問題，不容易受地理的影響，獲取影像的周期也較短，減輕了工作人員的壓力，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，除了傾斜攝影和小面積測繪會采用多旋翼，一般工程測繪主要采用固定翼無人機(jī)或垂直起降無人機(jī)。采購方需根據(jù)需求選配無人機(jī)飛行平臺（多旋翼/固定翼），測繪測量設(shè)備一般比較貴重，建議選擇知名廠家產(chǎn)品。小面積推薦選配多旋翼無人機(jī)，大面積推薦固定翼無人機(jī)，當(dāng)然也得看其負(fù)載能力的大小，具體情況視情況而定。
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.
