Abstract

The invention discloses a knowledge-constrained bridge target image pneumatic optical effect correction method. According to the method, a space constraint relationship knowledge base between a bridge target and a background area is established on a ground; ground preparation is carried out before a flight, and the space constraint relationship knowledge base is used to establish a multi-scale template; images taken during a high speed flight are preliminarily corrected by a pneumatic optical effect, then an interested bridge area is extracted, and then a target area of the interested bridge area is precisely corrected; and finally the corrected interested bridge target area and the background area are merged to obtain a processed real-time remote sensing flight image. In the invention, the space constraint relationship knowledge base is established; for the real-time bridge images captured in the hypersonic situation, the constraint knowledge is used to extract the interested bridge area to carry out the pneumatic optical effect precise correction; the correction accuracy of the bridge target is ensured; and the real-time performance of the correction is greatly improved.

Description

technical field [0001] The invention belongs to the intersection field of aerospace science and technology and digital image processing technology, and specifically relates to an airport image intelligent correction method based on knowledge constraints, which is applied to the navigation, remote sensing and detection of hypersonic aircraft. Background technique [0002] Remote sensing, detection, navigation and guidance of hypersonic vehicles is an important field in the development of the aerospace industry in the 21st century, and it has important scientific significance and application value in the future high-tech and national economic development. Remote sensing, detection, navigation, and guidance based on hypersonic vehicles face the challenge of aero-optical effects. [0003] Aero-optics is a subject that studies the influence of high-speed flow on imaging and detection of high-speed aircraft. When a high-speed aircraft with an optical imaging detection system flie...
