Abstract
In the field of remote sensing imaging, multispectral imaging can obtain an image of the observed scene in several bands, while the light detection and ranging (LiDAR) can acquire the accurate 3D geometric information of the scene. With the development of remote sensing technology, how to effectively integrate the two imaging technologies in order to collect and process simultaneous spectral and 3D geometric information has been one of the frontier problems. Most of the present researches on simultaneous spectral and geometric data acquisition focus on the design of physical multispectral LiDAR system, which inevitably lead to an imaging system of heavy weight and high power consumption and thus inconvenient in practice. Different from the present researches, a UAV-based integrated multispectral-LiDAR system is introduced in this paper. Through simultaneous multi-sensor data collection and multispectral point cloud generation, a low-cost and UAV-based portable 3D geometric and spectral information acquisition system can be achieved.
