Method and device for automatically extracting contour of coastal zone breeding factory

Abstract

The invention provides a method and device for automatically extracting the contour of a coastal zone breeding factory, a convolutional neural network model is constructed to extract the position and reference contour of the breeding factory in a remote sensing image, and the contour of the breeding factory in the remote sensing image is extracted according to the features of different breeding factories in a large area in combination with ground feature linear features and an image segmentation algorithm. And corresponding line segment information, corner point information and azimuth information are extracted, so that ground object vector optimization and contour information correction are completed, and the requirement of rapid extraction is met. According to the method, the problems of much human intervention, long acquisition time, non-uniform standard and the like in the existing cultivation factory contour extraction are solved, and the requirements of users on high-frequency contour extraction of the monitoring area in different application scenes can be met, so that the coastal zone cultivation factory contour information product is automatically extracted.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a method and device for automatically extracting the outline of a coastal zone breeding factory. Background technique [0002] Digitization and precision of fishery breeding settings are the core content of the development of smart fishery. Therefore, it is very important to quickly and accurately extract the contours of fishery breeding facilities. At the same time, these contour information are of great significance for quickly locating the location of the breeding factory and monitoring the dynamic changes of the breeding. [0003] At present, the outline extraction methods of fish farming settings can be summarized into three categories: one is based on the traditional on-site measurement of the information of each landmark point of the building, and then obtains the outline of the breeding factory in the form of computer-aided mapping; the other is the use of high-r...
