High-resolution hyperspectral imaging method and device based on dual-optical-path RGB fusion

The invention discloses a high-resolution hyperspectral imaging method and device based on double-light-path RGB fusion. The method comprises the steps that RGB images of two light paths of the same scene are fused to obtain a fused image; performing reversed-sequence uniform sampling on the time steps from the maximum time step number T; the method comprises the following steps: firstly, calculating noise-added high-frequency information when a time step is the maximum time step number T; secondly, for each time step, solving the noise-added high-frequency information of the time step according to the noise-added high-frequency information of the time step until the noise-free high-frequency information is obtained; and finally, adding the fused image and the noise-free high-frequency information to obtain a hyperspectral image. The invention aims to obtain the high-resolution hyperspectral image for the RGB images of the two light paths of the same scene, so that the acquisition precision of the hyperspectr
