Embodiment Construction

[0082] The present invention will be further described below in conjunction with specific embodiments. The exemplary embodiments and descriptions of the present invention are used to explain the present invention, but not as a limitation to the present invention.

[0083] Such as figure 1 The shown infrared multispectral raw image processing method comprises the following steps:

[0084] 1) Image restoration: The image restoration includes missing element filling, front and back scan misalignment correction, front and back scan consistency correction, response consistency correction within the spectrum, B7 spectrum de-interference, B8 spectrum missing line filling, B9 band Interpolation, B9 band to remove pinstripes, B9 band to remove stripes and tailing:

[0085] Filling of missing elements: Due to the problems in the data transmission system, although the detector unit has received the surface radiation information, sometimes there will be a phenomenon of missing elements w...

Abstract

The invention discloses an infrared multispectral original image processing method comprising image restoration, radiation correction, and geometric correction. Image restoration includes missing element filling, forward and reverse scanning mismatch correction, forward and reverse scanning consistency correction, spectral response consistency correction, B7 spectrum interference removing, B7 spectrum missing row filling, B9 band interpolation, B9 band pinstripe removing, and B9 band stripe tail removing. Geometric correction includes correction of deformation caused by imaging and projecting modes, image distortion caused by earth curvature change, influence of atmospheric refraction and influence of earth rotation. Compared with the prior art, the image processing level is improved obviously, and the project image quality is obviously improved than ever before by adopting the method of the invention.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to an infrared multispectral original image processing method. Background technique [0002] Remote sensing is to carry out ground feature identification and special research through the processing, analysis and interpretation of gray level information reflecting the level of electromagnetic wave radiation of ground features. Due to the influence of various factors in the process of remote sensing imaging (such as satellite speed changes, the interaction between the atmosphere and ground objects reflecting and emitting electromagnetic waves, random noise, etc.), the actual gray value of the image is not entirely the size of the electromagnetic wave energy radiated by the ground objects. The reflection of the above factors also includes the results of the above factors, so before the remote sensing image processing, it is necessary to perform correction processing (image res...
