Leica Geosystemsannounces major efficiency improvement to airborne urban mapping solution

(Heerbrugg, Switzerland, 17 September 2019) –Leica Geosystems, part of Hexagon, introduces the Leica CityMapper-2. This next generation hybrid oblique imaging and LiDAR sensor provides fast and efficient digitisation of cities.

As part of Leica Geosystems’ RealCity solution, which combines the CityMapper-2 with the Leica HxMap high-performance processing workflow, the new sensor is designed to provide faster updates while preserving image quality over a wide range of flying conditions.

最显着的改进来自新开发的光学系统，其中包括两个Nadir（RGB＆NIR）和四个使用CMOS技术的斜肌150 MP度量摄像机，并配备了Leica Geosystem的独特机械前进动力补偿（FMC）。激光雷达传感器的脉冲重复频率已增加到2 MHz，并具有无量化的多脉冲（MPIA）技术。

“这款新开发的混合动力成像和LiDAR传感器是市场上最先进的机载传感器，用于高度生产的3D数字双胞胎，”said John Welter, Hexagon's Geospatial Content Solutions president。“我们很高兴提供一种解决方案，以改变我们的行业实现我们生活的世界数字化的方式，以最有效地帮助管理它。”

The new optical system uses backside illumination (BSI) CMOS technology and customised low-distortion lenses specifically designed to deliver the highest image quality and photogrammetric accuracy without reducing collection efficiency. While traditional camera systems restrict operators to high shutter speeds or decreased aircraft speed to control image blur, mechanical FMC allows the CityMapper-2 to capture high quality imagery even in difficult lighting conditions with no reduction in efficiency.

LIDAR传感器可提供3厘米范围的精度，并在城市景观中进行了优化的数据捕获，以提供非常准确的数据，甚至在整个数据集中分布。

Leica CityMapper-2 is a compact package with embedded system controller and storage which makes it easy to install in any survey aircraft.该系统有两种配置可用于标准和高空飞行，以满足客户的需求和当地飞行法规。

The sensor is supported by HxMap, the unified multi-sensor high-performance processing workflow available for all Leica Geosystems airborne sensors. The software suite has the capability to process imaging and LiDAR data in the same user interface, reducing the training requirements for staff when processing data from different sensors. Combining the new CityMapper-2 with HxMap offers the foundation to produce all airborne data products for smart decision making in rapidly changing urban environments.
