Leica AHAB DragonEye Dual Head Oblique

Leica AHAB DragonEye Dual Head
Oblique LiDAR System
Industry-leading 1 MHz airborne oblique LIDAR system
Equipped with two oblique scanner heads, Leica AHAB DragonEye Dual Head is the first airborne LiDAR system able to capture, digitize
and analyze full waveform LiDAR data in real time at pulse rates up to 1 MHz. In the same sensor head, DragonEye Dual Head includes a Leica RCD30
camera which simultaneously captures 80 MPIX RGB + near infrared high-resolution photos.
The innovative dual scanner head design creates not only a preeminent point density (>16 pts/m2 @1000m AGL), but also features a unique oblique
scan pattern. In one single pass, each ground target will be illuminated by four laser shots at multiple incidence angles from ±8 to ±20 degrees,
maximizing vertical surface definition and minimizing shadows in the survey data.
Such innovative design makes DragonEye Dual Head a perfect tool for complicated applications such as city modelling and forest survey. Moreover, the
true Multiple-Pulse-in-Air (MPiA) feature allows the system to fully utilize the high laser pulse rate by collecting multiple pulses in the air up to 1600 m
AGL. DragonEye Dual Head is compatible with the Leica PAV100 Gyro-stabilized mount, which compensates for the aircraft movement and significantly
improves both the data accuracy and survey efficiency.
