  • 融合SNIC超像素与Canny边缘检测,分步优化图像分析
  • 在哨兵2号数据上实现高精度农田边界提取,效果稳定可靠
  • 适合大规模农业遥感监测,尤其适用于云平台处理

高效利用耕地是农业可持续发展和保障粮食安全的关键。随着发达国家卫星技术的快速发展,亟需更准确、可操作的耕地识别方法。基于卫星影像光谱分析的农田边界识别被认为是现代农业中最优且精确的方法之一。本文提出一种新方法,利用谷歌地球引擎(GEE)平台获取的卫星数据,结合“简单非迭代聚类(SNIC)超像素”与“Canny边缘检测”两种算法,实现对耕地适宜性及绿度指数的评估。SNIC将影像像素聚合成具有相似特征的较大区域(超像素),提升分析质量;Canny方法则检测图像中突变边缘,精确定位农田边界。本研究基于哨兵2号(Sentinel-2)高分辨率多光谱数据及GEE JavaScript API开展,结果表明该方法能有效、可靠地分类随机选取的农田地块。二者协同使用可降低卫星图像中异常值的影响,显著提高农田边界判定精度,为大范围农业监测与资源管理提供更准确的地图支持。同时拓展了云平台与人工智能在农业领域的应用潜力。

原文摘要 · Abstract (English)

Efficient use of cultivated areas is a necessary factor for sustainable development of agriculture and ensuring food security. Along with the rapid development of satellite technologies in developed countries, new methods are being searched for accurate and operational identification of cultivated areas. In this context, identification of cropland boundaries based on spectral analysis of data obtained from satellite images is considered one of the most optimal and accurate methods in modern agriculture. This article proposes a new approach to determine the suitability and green index of cultivated areas using satellite data obtained through the "Google Earth Engine" (GEE) platform. In this approach, two powerful algorithms, "SNIC (Simple Non-Iterative Clustering) Super Pixels" and "Canny Edge Detection Method", are combined. The SNIC algorithm combines pixels in a satellite image into larger regions (super pixels) with similar characteristics, thereby providing better image analysis. The Canny Edge Detection Method detects sharp changes (edges) in the image to determine the precise boundaries of agricultural fields. This study, carried out using high-resolution multispectral data from the Sentinel-2 satellite and the Google Earth Engine JavaScript API, has shown that the proposed method is effective in accurately and reliably classifying randomly selected agricultural fields. The combined use of these two tools allows for more accurate determination of the boundaries of agricultural fields by minimizing the effects of outliers in satellite images. As a result, more accurate and reliable maps can be created for agricultural monitoring and resource management over large areas based on the obtained data. By expanding the application capabilities of cloud-based platforms and artificial intelligence methods in the agricultural field.
