Abstract

The invention discloses an image flow-based near-real-time remote sensing image online target detection method, and belongs to the technical field of remote sensing image processing. The method comprises the steps of obtaining a basic parameter of an image; obtaining the maximum size of a target; calculating maximum pixels occupied by the target; obtaining a time calculation complexity function ofa target detection algorithm; calculating the number of image blocks needed to be subjected to target detection; calculating total calculation complexity of image division; obtaining a row number ofeach detection; performing target detection on block images by utilizing the target detection algorithm; and the like. According to the method, image target detection can be performed while image production is performed, so that remote sensing image storage resources and calculation resources can be reduced; and the method has extremely low calculation complexity during block processing.

Description

technical field [0001] The invention relates to the technical field of remote sensing image processing, in particular to an image stream-based near real-time remote sensing image online target detection method. Background technique [0002] With the rapid development of satellite remote sensing technology, especially the development of high-resolution remote sensing technology, multi-source, high-resolution remote sensing data is growing explosively, and the storage and processing of remote sensing data has encountered unprecedented challenges. In remote sensing image applications, such as military applications, users are often interested in the part of the image that contains the target. For these users, a large number of background images are invalid information, and the storage and processing of these data not only waste a large amount of storage and computing resources, but at the same time, the effective information is submerged in the massive data, making it more diffi...
