Java解析照片拿到GPS位置数据的详细步骤

Java解析照片拿到GPS位置数据的详细步骤

目录1.前提条件2.代码环境

java代码逐步解析照片拿到GPS位置数据，附上步骤讲解，附上源代码和jar包依赖

1.前提条件

第一，检查你图片是否是高清原图；第二，检查你的图片是否来自IPhone设备;第三，检查你拍照片时，是否打开了GPS；三者缺一不可

2.代码环境

A：需要的Jar包：

com.drewnoakes

metadata-extractor

2.12.0

B：开发环境

1.maven 引入jar包2.JDK 1.83.windows OS

C：核心代码

import com.drew.imaging.jpeg.JpegMetadataReader;

import com.drew.imaging.jpeg.JpegProcessingException;

import com.drew.metadata.Directory;

import com.drew.metadata.Metadata;

import com.drew.metadata.Tag;

import java.io.File;

import java.io.IOException;

import java.util.Iterator;

public class PictureTest {

public static void readPic() {

System.out.println("开始读取图片信息...");

File jpegFile = new File("18.jpg");

Metadata metadata;

try {

metadata = JpegMetadataReader.readMetadata(jpegFile);

Iterator it = metadata.getDirectories().iterator();

while (it.hasNext()) {

Directory exif = it.next();

Iterator tags = exif.getTags().iterator();

while (tags.hasNext()) {

Tag tag = (Tag) tags.next();

System.out.println(tag);

}

}

System.out.println("图片信息读取完成！");

} catch (JpegProcessingException e) {

e.printStackTrace();

} catch (IOException e) {

}

}

}
