Javaでオリジナル写真を解析して位置情報を取得する（ソースコード付き、テスト済み、利用可）

1. 前提条件

まず、お使いの画像がHDのオリジナル画像であることを確認してください。



次に、画像がアイフォン端末のものであるかどうかを確認します。



3つ目は、撮影時にGPSがオンになっているかを確認することです。



3つのうち1つが欠けている

2. コード環境

A: 必要な Jar パッケージ。

 <dependency>
            <groupId>com.drewnoakes</groupId>
            <artifactId>metadata-extractor</artifactId>
            <version>2.12.0</version>
 </dependency>

B：開発環境

1. maven to introduce jar packages
2.JDK 1.8
3.windows OS

C: コアコード

        System.out.println("Start reading picture information... ");
        File jpegFile = new File("18.jpg");
        Metadata metadata;
        try {
            metadata = JpegMetadataReader.readMetadata(jpegFile);
            Iterator<Directory> it = metadata.getDirectories().iterator();
            while (it.hasNext()) {
                Directory exif = it.next();
                Iterator<Tag> tags = exif.getTags().iterator();
                while (tags.hasNext()) {
                    Tag tag = (Tag) tags.next();
                    System.out.println(tag);
                }
            }
            System.out.println("Image information reading complete! ");
        } catch (JpegProcessingException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}
