Abstract

The invention provides a method and device for collecting crop type samples, comprising the following steps: obtaining sample data with location information from a social network data platform; performing vector conversion processing on the text data to obtain text vector data according to the location information in the text data , and obtain the remote sensing data corresponding to the position information; respectively calculate the position confidence of the sample data according to the text vector data, calculate the spectral confidence of the sample data according to the remote sensing data, and calculate the image matching degree of the sample data according to the picture data; based on the preset sample Screening rules to determine the availability of sample data based on the location confidence, spectral confidence, and image matching of the sample data. The present invention can solve the problems of time-consuming and labor-intensive acquisition of sample points, inability to obtain historical samples, doubtful accuracy and limited range in the current method of obtaining sample points.

Description

technical field [0001] The invention relates to the technical field of remote sensing mapping, and more specifically, to a method and device for collecting crop type samples. Background technique [0002] Remote sensing technology has the advantages of large-scale, long-term and dynamic monitoring. Different ground features exhibit different spectral characteristics, which makes remote sensing technology widely used in land cover mapping. Crop area mapping is a further subdivision of agricultural land types in land cover mapping. There are many types of crops, and the rotation of planting areas changes frequently. Opportunities and challenges coexist. [0003] In the process of remote sensing mapping of crop planting areas, efficiently obtaining relatively accurate and considerable sample points is the first step in remote sensing mapping, and it is also a difficult problem to solve. [0004] Current research often obtains sample points through the following three methods...
