机载激光雷达最近最大的变化是在数据处理方面。现在，数据处理更加自动化和精简，通常使用完全基于云的架构，还包括云中的手动编辑和质量保证（QA）。这种基于云计算的方法使现场和办公室之间的周转时间大大加快，并具有更多的通用性。

现在，在飞机降落回停机坪后，很快就可以上传项目数据，在某些情况下，后处理的数据也会在云端交付。

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.

对比传统的航测系统，无人机搭载激光雷达系统进行测绘主要有几大优势：分辨率高，激光雷达可以获得极高的角度、距离和速度分辨率，可以利用多普勒成像技术获得非常清晰的图像。

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，激光直线传播、方向性好、光束非常窄，弥散性非常低，精度很高。抗有源干扰能力强，与微波、毫米波雷达易受自然界广泛存在的电磁波影响的情况不同，自然界中能对激光雷达起干扰作用的信号源不多，因此激光雷达抗有源干扰的能力很强。

激光雷达系统拥有强大的内置信号处理、大视野和多段测量功能，可以产生关键的距离数据以及进行高效的障碍物检测，可实现长输线路的高精度通道测量、线路杆塔的塔倾和沉降检测、线路垂弧预警及线路周围树木、山体、地质灾害对线路的威胁预警。

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.

无人机相比传统人工巡检不仅效率高而且更简单和安全，无人机可自动巡航自动采集，上传影像信息，自动分析缺陷，并自动形成缺陷报告。

采购方需根据自己工作性质选购设备，如果是灵活机动性则优先考虑多旋翼和垂起固定翼无人机，若固定线路常态化巡检则考虑无人机机场。另外，如果需经常爬山涉水则考虑轻小型便携无人机。

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.
