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

大都市地区准确的航空数据的需求超出了传统的数据产品，因为快速变化的城市环境需要更频繁的频率，因此更有效地更新地理空间底层层。bob综合app下载

The Leica CityMapper-2 is specifically designed for airborne urban mapping and offers twice the data collection performance to addresses the urgent need for 3D data. The world’s only hybrid oblique imaging and LiDAR airborne sensors, captures two nadir (RGB/NIR) and four oblique 150 MP images every 0.9 seconds providing the highest resolution to visualise every corner of the city. With a new generation 2 MHz pulse rate LiDAR, this sensor breaks all conventional barriers of urban mapping.

The newly developed Leica MFC150 optical system is equipped with Leica Geosystem’sunique 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 decrease shutter and aircraft speeds 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.

性能助推器

Allowing users to collect at 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 of莉卡实体，CityMapper-2旨在在最短的时间内创建数字双城市，运营费用最低。

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.
