Abstract

The invention discloses a multispectral imaging method and device based on an RGB camera and a deep neural network, and the method comprises the following steps: designing a convolutional neural network which takes a mosaic image as an input and takes a corresponding multispectral image as an output; training the convolutional neural network by using the existing multispectral data set to obtain an optimal network model; and shooting by adopting an RGB color camera to obtain a current mosaic image of an actual scene, and taking the mosaic image as the input of the optimal network model to obtain a target multispectral image. According to the method, calculation imaging from mosaic images to multispectral images can be directly completed by utilizing the deep neural network, and the methodis more suitable for practical application and is simple and easy to implement.

Description

technical field [0001] The invention relates to the technical field of computational photography, in particular to a multispectral imaging method and device based on an RGB camera and a deep neural network. Background technique [0002] Multispectral imaging technology emerged in the 1980s. It combines spectral technology and imaging technology to obtain information of multiple bands for each pixel of the image. Compared with ordinary color cameras, such as the three spectral channels of RGB cameras, multispectral imaging systems generally contain dozens or even hundreds of spectral channels, and each spectral band can be regarded as a static grayscale image, representing different bands. Intensity information, images on different spectral bands contain more spatial information and spectral information of the observed object. Compared with traditional imaging technology, multispectral imaging technology has great advantages. It can understand and recognize observation targe...
