Leica CityMapper-2 High-Performance Urban Mapping Sensor

对于城市快速有效的数字化，这种混合倾斜成像和LiDAR解决方案提供了最高的生产率和无与伦比的数据精度

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设计create digital twins of cities in the shortest time, with the lowest operating expense.

出色的准确性

The newly developed Leica MFC150 cameras with customised low-distortion lenses can deliver pixel sizes as small as 2 cm at high flying speeds thanks to mechanical forward-motion-compensation (FMC). The 2 MHz linear-mode LiDAR sensor delivers 3 cm range accuracy and is optimised for data collection in urban environments.

Operational Flexibility

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.
