Google Earth Engine——无人机影像进行分类处理

本次我们是利用无人机影像采集的影像数据，对特征点的一些特征进行提取分析，然后再加载的矢量转化的过程中出现了以下问题，主要是超限，另外还有几个函数可以

ee.Algorithms.Image.Segmentation.seedGrid(size, gridType)
选择用于聚类的种子像素。

参数。
size（整数，默认：5）。
超级像素的种子位置间距，单位是像素。

gridType（字符串，默认为 "方形"）。
网格的类型。正方形 "或 "六角形 "之一。

返回。图像

ee.Algorithms.Image.Segmentation.SNIC(image, size, compactness, connectivity, neighborhoodSize, seeds)
基于SNIC（简单非迭代聚类）的超级像素聚类。输出一个群集ID的频段和每个输入频段的每一个群集的平均数。如果没有提供 "种子 "图像作为输入，输出将包括一个包含生成的种子位置的 "种子 "带。见。Achanta, Radhakrishna和Susstrunk, Sabine，"使用简单非迭代聚类的超级像素和多边形"，CVPR，2017。

参数。
image（图像）。
用于聚类的输入图像。

size（整数，默认：5）。
超级像素种子位置的间隔，单位是像素。如果提供 "种子 "图像，则不产生网格。

compactness（浮点数，默认为1）。
紧凑度系数。较大的数值会使集群更加紧凑（方形）。将此设置为0会使空间距离加权失效。

connectivity（整数，默认：8）。
连通性。4或8都可以。

neighborhoodSize（整数，默认为空）。
瓦片邻域大小（避免瓦片边界伪影）。默认为2*大小。

seeds（图像，默认为空）。
如果提供，任何非零值的像素都被用作种子位置。相互接触的像素（由 "连通性 "指定）被认为属于同一个集群。

返回。图像

ee.Reducer.countEvery()

Returns a Reducer that computes the number of inputs.

No arguments.

Returns: Reducer

返回一个计算输入数的Reducer。
