Hyperspectral imaging method, device and system

Abstract

The invention provides a hyperspectral imaging method, device and system and relates to the technical field of spectral imaging. The method comprises the steps of: controlling a linear array detectorto perform shooting in a first track in a first direction; after the shooting of the first track is finished, controlling the linear array detector to move to a second track along a second direction so as to control the linear array detector to perform shooting in the second track in the first direction; completing the shooting of all the tracks in the first directions in the same manner to obtaina hyperspectral image. All the tracks in the first direction are arranged in the second direction. The field angle of hyperspectral imaging can be increased and the hyperspectral imaging quality canbe improved.

Description

technical field [0001] The present invention relates to the technical field of spectral imaging, in particular to a hyperspectral imaging method, device and system. Background technique [0002] Hyperspectral remote sensing technology combines spectral technology and imaging technology, and is an important direction for the development of earth observation sensing technology in the world. Specifically, hyperspectral imaging technology adds a spectral dimension to two-dimensional imaging. The radiation of the measured object is decomposed into spectral radiation of different bands through the spectrometer system, and dozens of images per pixel can be obtained in a spectral interval. Even hundreds of continuous narrowband information. Hyperspectral data is of great significance for the identification and analysis of ground features, and has been widely used in many fields such as mineral exploration, agricultural and forestry resource investigation, environmental monitoring, ...
