Remote sensing detection method based on UAV platform

Abstract

A remote sensing detection method based on an unmanned aerial vehicle platform belongs to the field of remote sensing and surveying and mapping. The invention aims at the problem that existing spectrum image data and lidar point cloud data cannot be effectively fused due to multi-source heterogeneity. Including: mount the spectrum detector and LiDAR detector as an overall frame under the UAV; use the UAV ground station to control the UAV flight controller to send data acquisition commands to the microcontroller, and then detect the spectrum detector and LiDAR Synchronous acquisition and control of the IMU / GPS integrated navigation unit; data registration to obtain the spatial correspondence between the two data; up-sampling of the collected data to achieve spatially consistent sampling of the data; and then according to the spatial correspondence, the spectrum The image data and LiDAR point cloud data are fused to obtain multi / hyperspectral point cloud data. On the basis of realizing integrated detection of image-spectrum-space multi-dimensional data, the present invention fuses spectral and spatial information to finally generate a spectral point cloud.

Description

technical field [0001] The invention relates to a remote sensing detection method based on an unmanned aerial vehicle platform, and belongs to the field of remote sensing and surveying and mapping. Background technique [0002] Remote sensing (Remote Sensing) is defined as a means of acquiring and measuring environmental (target, material, phenomenon) attribute information without direct contact. In terms of space technology, remote sensing usually refers to a method of recording the electromagnetic energy emitted or reflected by the earth's land surface, oceans, regions or objects in the atmosphere; The data collected by remote sensing can realize the distinction of different types of objects. Remote sensing data are generally collected by remote sensing instruments installed on aircraft or Earth-orbiting spacecraft, which gives scientists the opportunity to observe and analyze geographical areas of larger scenes; therefore, in fire monitoring, glacier monitoring, coastal ...
