Research on Extraction Method of Shoreline Based on Airborne Remote Sensing Image

Abstract

Shoreline information extraction is an important basis for marine supervision and development. Due to the high-time-cost and low-extraction-accuracy of the traditional shoreline extraction method based on field investigation and artificial interpretation, a new shoreline extraction method based on airborne remote sensing and segmentation technology was proposed. First, the visible and thermal infrared images were matched into the same size and the two images were fused by the method of image processing. Then, the triangle threshold method was used to segment the image for separating the land and the sea. Finally, the shorelines were extracted by removing speckles. The experiment result shown that the segmentation algorithm based on UAV remote sensing image is simple and easy to realize, which can extract shorelines quickly, accurately and intelligently.
