Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that the data obtained based on remote sensing technology needs to be compared with the images in the process of interpretation. The comparison method is relatively complicated, which is not intuitive enough for interpreters, and makes the interpretation work difficult. It requires more experience and time, the selection of samples is not objective and accurate enough, and the accuracy of classification results is not high. However, providing convenient and intuitive operation can improve the efficiency and accuracy of remote sensing interpretation, and reduce the interpretation experience requirements for interpreters. A Method of Field Sampling to Improve the Efficiency of Remote Sensing Interpretation

example 1

[0040] Example 1, using a method for improving the efficiency of remote sensing interpretation provided by the present invention to conduct field sampling to investigate a certain target area, such as figure 1 As shown, the specific operation includes the following steps:

[0041] Step 1), Field Sampling: After receiving the crop area identification task, send field investigators to the target area to conduct investigations. Field investigators carry mobile information collection terminals such as mobile phones or tablet computers, and according to the remote sensing interpreters delineated Sampling area, draw some plots by random sampling along the road ( figure 2 The schematic diagram of the demarcated sampling area is shown), and the sample area report is formed by observing the sample site conditions and collecting the sample site information, such as image 3As shown, you can intuitively input and record plot attribute information and planting crop information directly ...

example 2

[0047] Example 2, using the existing commonly used remote sensing technology interpretation method provided in the background technology to investigate a certain target area, the specific operation includes the following steps:

[0048] ① Establishment of interpretation signs;

[0049] ② Select the sample area on the image according to the established interpretation mark;

[0050] ③ According to the selected samples, choose the appropriate method for classification and interpretation;

[0051] ④ Check and modify the results after classification to complete the interpretation.

[0052] It can be seen from the above process that the first thing that must be done in the interpretation process is to establish the interpretation flag, which is directly related to the basis and accuracy of the later machine classification. Several important steps must be followed to establish interpretation marks, including understanding image characteristics, conducting field surveys, field selec...

Abstract

The invention belongs to the technical field of remote sensing data interpretation methods and relates to a method for improving the remote sensing interpretation efficiency by field sampling, which can reduce the workload of interpreters and improve the image interpretation precision. The method comprises the steps that field sampling is conducted through drawing software of a mobile terminal, asampling result is exported from equipment to a computer terminal, an exported result (vector data) is superposed on a remote sensing image, and interpretation is completed by comparing a sampling photo and the image. The method for improving the remote sensing interpretation efficiency by field sampling provided by the invention has the advantages that the operation is convenient and visual, theremote sensing interpretation efficiency and precision can be improved, and the requirement on interpretation experience of interpreters is reduced.

Description

technical field [0001] The invention belongs to the technical field of remote sensing data interpretation methods, and in particular relates to a method for field sampling and improving remote sensing interpretation efficiency, which can reduce the workload of interpreters and improve image interpretation accuracy. Background technique [0002] The extraction of remote sensing crop area requires the use of remote sensing data to calculate the area through image interpretation. Only correct image interpretation can ensure the accuracy of crop area.
