Fig. 4: Real-time hyperspectral UAV scene reconstruction.

From: Hardware-accelerated integrated optoelectronic platform towards real-time high-resolution hyperspectral video understanding

Fig. 4

a Distribution of spectral reconstruction difference for a reconstructed hyperspectral frame image (inset) at 204 bands using the platform of Fig. 2 at 30 FPS and a commercial SPECIM IQ operating at 0.016 FPS. b Camera module with hardware encoders integrated on DJI Matrice 300 RTK drone, the inset shows a closeup of the camera. c Raw frames in the hyperspectral UAV video sequence. d Visualization of a single hyperspectral frame acquired by the drone at 30 FPS. e Power density spectrum (PDS) retrieved at the spatial pixel p in panel d. f Reconstructed three-dimensional hyperspectral map from the video sequences, with spectral distribution visualized via K-MEANS clustering. g Cluster’s spectral distribution. Source data are provided as Fig. 4 data.
