Abstract

The invention provides a remote sensing image target detection method and system. The method comprises a target recognition and extraction step and a false alarm elimination step. According to the characteristics of on-satellite data processing, corresponding feature description, detection and matching algorithms are designed by utilizing the characteristics of invariance of edges, shapes, scales and the like of typical large ground targets such as airports, bridges and oil depots, and are optimized, so that real-time and accurate detection processing of the on-satellite large ground targets is realized. By applying the remote sensing data processing method provided by the invention, the fixed target can be quickly and accurately detected and recognized from the high-resolution remote sensing image; and meanwhile, the multi-feature matching model is established as a classification basis of the fixed target, so that the target recognition precision can be effectively improved.

Description

technical field [0001] This application relates to the field of data processing technology, especially on-board remote sensing data processing technology. Background technique [0002] The problem of target detection has always been an important research direction of computer vision. Its main task is to determine whether there is a target to be detected in the image, and to extract and accurately locate it. To solve this problem, comprehensively use methods such as mathematics, physics, and information science to realize the inversion from object data recording to object characteristics and their temporal and spatial distribution and changes, involving remote sensing, pattern recognition, machine vision, etc. , is a typical interdisciplinary problem. [0003] With the development of sensor technology, space technology, information processing technology, and small satellite technology, the temporal, spatial, and spectral resolution capabilities of remote sensing images have ...
