Leica CityMapper-2高性能城市地图传感器

For fast and efficient digitisation of cities, this hybrid oblique imaging and LiDAR solution provides the highest productivity and unmatched data accuracy

The need for accurate aerial data in metropolitan areas goes beyond traditional data products because the fast-changing urban environments require more frequent and hence more efficient updates of geospatial base layers.

Leica CityMapper-2专为空降城市地图而设计，并提供了两倍的数据收集性能，以满足3D数据的迫切需求。世界上唯一的混合倾斜成像和LIDAR空中传感器，每0.9秒捕获两个Nadir（RGB/NIR）和四个倾斜的150 MP图像，提供了最高的分辨率，以可视化城市的每个角落。使用新一代2 MHz脉搏率激增，该传感器打破了所有常规的城市映射屏障。

新开发的Leica MFC150光学系统配备了Leica Geosystem的unique mechanical forward-motion-compensation (FMC), which allows to capture high quality imagery even in difficult lighting conditions with no reduction in efficiency, unlike traditional camera systems that have to increase the shutter speed and decrease the aircraft speed to control image blur.

The CityMapper-2 is the best equipped airborne solution in the market for highly-productive creation of 3D digital twins of cities. The sensor transforms how we digitise the world we live in and allows you to create the most detailed geospatial base layer including orthophotos, point clouds, 3D building models and meshes, all from one single flight.

Performance Booster

允许用户收集在higher flying heights and speeds while still delivering the same GSD and positional accuracy, this system provides unmatched efficiency for urban mapping applications. As part ofLeica RealCity, CityMapper-2 is designed to create digital twins of cities in the shortest time, with the lowest operating expense.

Outstanding Accuracy

新开发的带有定制低距离镜头的Leica MFC150摄像头可以在高飞行速度下以机械前进速度（FMC）提供高至2 cm的像素尺寸。2 MHz线性模式LIDAR传感器可提供3 cm范围的精度，并在城市环境中进行了优化。

操作灵活性

The system is available in three configurations for low, standard and high-altitude flights to meet customers’ needs and to adapt to local weather and flight regulations. The CityMapper-2 is a compact package with embedded system controller and storage, which makes it easy to install in any survey aircraft.

Highest Data Throughput

TheLeica HxMaphigh-performance workflow was upgraded to meet the demands of CityMapper-2 data processing. Edge computing creates fully calibrated high quality image data for rapid QC and emergency response applications. On the LiDAR side, discrete returns are extracted from the full waveform for the fastest processing speeds.
