簡介：LiDAR激光探測與測量，也就是激光雷達。是一種遙感技術(shù)，它使用快速激光脈沖來繪制地球表面的地圖。LiDAR 在用于創(chuàng)建用于各種業(yè)務(wù)應(yīng)用程序的高分辨率數(shù)字表面、地形和高程模型時非常有用。
Introduction: LiDAR laser detection and measurement, also known as LiDAR. It is a remote sensing technology that uses fast laser pulses to map the surface of the Earth. LiDAR is very useful for creating high-resolution digital surface, terrain, and elevation models for various business applications.

機載激光雷達最近最大的變化是在數(shù)據(jù)處理方面。現(xiàn)在，數(shù)據(jù)處理更加自動化和精簡，通常使用完全基于云的架構(gòu)，還包括云中的手動編輯和質(zhì)量保證（QA）。這種基于云計算的方法使現(xiàn)場和辦公室之間的周轉(zhuǎn)時間大大加快，并具有更多的通用性。
現(xiàn)在，在飛機降落回停機坪后，很快就可以上傳項目數(shù)據(jù)，在某些情況下，后處理的數(shù)據(jù)也會在云端交付。
The biggest recent change in airborne LiDAR is in data processing. Nowadays, data processing is more automated and streamlined, typically using a completely cloud based architecture, including manual editing and quality assurance (QA) in the cloud. This cloud computing based approach greatly accelerates the turnaround time between on-site and office operations, and has more versatility.
Now, after the plane lands back on the apron, project data can be uploaded quickly, and in some cases, the post-processing data will also be delivered in the cloud.
對比傳統(tǒng)的航測系統(tǒng)，無人機搭載激光雷達系統(tǒng)進行測繪主要有幾大優(yōu)勢：分辨率高，激光雷達可以獲得極高的角度、距離和速度分辨率，可以利用多普勒成像技術(shù)獲得非常清晰的圖像。
Compared to traditional aerial surveying systems, unmanned aerial vehicles equipped with LiDAR systems have several major advantages in surveying: high resolution, LiDAR can achieve extremely high angle, distance, and velocity resolution, and Doppler imaging technology can be used to obtain very clear images.
精度高，激光直線傳播、方向性好、光束非常窄，彌散性非常低，精度很高。抗有源干擾能力強，與微波、毫米波雷達易受自然界廣泛存在的電磁波影響的情況不同，自然界中能對激光雷達起干擾作用的信號源不多，因此激光雷達抗有源干擾的能力很強。
激光雷達系統(tǒng)擁有強大的內(nèi)置信號處理、大視野和多段測量功能，可以產(chǎn)生關(guān)鍵的距離數(shù)據(jù)以及進行高效的障礙物檢測，可實現(xiàn)長輸線路的高精度通道測量、線路桿塔的塔傾和沉降檢測、線路垂弧預(yù)警及線路周圍樹木、山體、地質(zhì)災(zāi)害對線路的威脅預(yù)警。
High accuracy, laser linear propagation, good directionality, very narrow beam, very low dispersion, high accuracy. Strong ability to resist active interference, unlike microwave and millimeter wave radars, which are susceptible to the widespread influence of electromagnetic waves in nature. There are not many signal sources in nature that can interfere with LiDAR, so LiDAR has a strong ability to resist active interference.
The LiDAR system has powerful built-in signal processing, wide field of view, and multi segment measurement functions, which can generate critical distance data and perform efficient obstacle detection. It can achieve high-precision channel measurement of long-distance transmission lines, tower tilt and settlement detection of transmission towers, line sag warning, and threat warning of trees, mountains, and geological disasters around the line to the line.

無人機相比傳統(tǒng)人工巡檢不僅效率高而且更簡單和安全，無人機可自動巡航自動采集，上傳影像信息，自動分析缺陷，并自動形成缺陷報告。
采購方需根據(jù)自己工作性質(zhì)選購設(shè)備，如果是靈活機動性則優(yōu)先考慮多旋翼和垂起固定翼無人機，若固定線路常態(tài)化巡檢則考慮無人機機場。另外，如果需經(jīng)常爬山涉水則考慮輕小型便攜無人機。
Compared to traditional manual inspections, drones are not only more efficient but also simpler and safer. They can automatically cruise and collect, upload image information, analyze defects, and generate defect reports.
The purchaser needs to choose equipment based on their job nature. If it is flexible, priority should be given to multi rotor and vertical fixed wing drones. If the fixed line is subject to regular inspection, drone airports should be considered. In addition, if you need to frequently climb mountains and wade in water, consider light, small, and portable drones.
