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.
