Abstract

The invention provides a method for splicing aviation multi-pixel parallel scanning images. According to the method, 'dimension plus rotation' transformational models are adopted in geometric transformational models of two adjacent frames, perspective projection models of area-array cameras are not adopted, the method adapts to the geometric transformational models between the adjacent aviation multi-pixel parallel scanning images, and the overall transformation problem between the adjacent images is well solved.

Description

technical field

[0001] The invention relates to the technical field of remote sensing image processing, in particular to a method for splicing aerial multivariate parallel-scanned images. Background technique

[0002] Aerial multiple parallel scanning is a panoramic photography camera derived from the traditional film era. It has a large side field of view and high resolution. It only needs a line array detector to obtain wide-format images. It is often used in infrared / Fast acquisition of night vision images. However, since the focal length of multiple parallel scanning cameras remains unchanged, the aircraft moves forward while scanning, and the non-linearity of the scanning mirror swing makes the image distortion more complicated. In order to obtain images of a certain area on the ground, multi-element parallel-scan cameras are often used to obtain images through the left and right sweeps of the objective lens during flight, and the adjacent images acquired before and a...
