以下仅使用大疆的图片作为参考，每种图片自定义的媒体信息有所不同，debug即可获得实际key值；

public static String[] getImageParam(InputStream inputStream) {
	try {
	    String[] param = new String[5];
	
	    Metadata metadata = JpegMetadataReader.readMetadata(inputStream);
	    for (Directory directory : metadata.getDirectories()) {
	
	        //获取图片的Exif拍摄时间
	        if (directory instanceof ExifIFD0Directory) {
	            ExifIFD0Directory exifIFD0Directory = (ExifIFD0Directory) directory;
	            exifIFD0Directory.getName();
	            param[4] = DateUtil.format.format(exifIFD0Directory.getDate(306));
	        }
	
	        if (directory instanceof XmpDirectory) {
	            XmpDirectory xmpDirectory = (XmpDirectory) directory;
	            Map<String, String> xmpProperties = xmpDirectory.getXmpProperties();
	
	            String degree = xmpProperties.get("drone-dji:GimbalYawDegree");
	            String lat = xmpProperties.get("drone-dji:GpsLatitude");
	            String lon = xmpProperties.get("drone-dji:GpsLongtitude");
	            String relativeAltitude = xmpProperties.get("drone-dji:RelativeAltitude");
	
	            param[0] = degree;
	            param[1] = lat;
	            param[2] = lon;
	            param[3] = relativeAltitude;
	        }
	    }
	    return param;
	} catch (Exception e) {
	    return null;
	}
}

该方法可以读取以下几种文件形式；JpegMetadataReader.readMetadata
