Description

Technical Field

[0001] The present disclosure relates to the technical field of spectral imaging, and in particular to a visible infrared spectral imaging device for a high-altitude unmanned aerial vehicle. Background Art

[0002] The imaging spectrometer combines optical imaging technology with spectral analysis technology to obtain the spectral image data cube of the target, thereby analyzing and identifying the target in terms of geometric shape and spectral characteristics. According to the different imaging methods, it can be divided into three categories: swing scanning, push scanning and staring. According to the different spectroscopic methods, it can be divided into three spectroscopic methods: grating (filter) spectroscopic, prism spectroscopic and interference spectroscopic.

[0003] At present, aerial imaging detection in a single visible near-infrared wavelength range or a single infrared wavelength range is not sufficient to fully monitor complex natural environment conditions. In addition, spectral image data cubes characterized by geometric shapes and spectral information cannot simultaneously obtain aircraft attitude information and target latitude, longitude, altitude and other geographic information. Finally, due to the inevitable pitch, roll and drift of drones flying at high altitudes, the continuity and stability of image quality are often difficult to guarantee.

[0004] Therefore, there is an urgent need for an infrared spectral imaging device that can improve the detection range, image quality continuity and stability of aerial imaging. Utility Model Content
