在命令行窗口中使用BoofCV JAR读取二维码

Question

我使用Zxing库读取二维码，但是，读取二维码的失败率相当高，正在寻找替代方案。

根据测试，BoofCV看起来很好：https://boofcv.org/index.php?title=Performance:QrCode

然而，我正在努力让它工作，并在Windows命令行中找到使用JAR文件的任何教程。

我有最新的0.33.1发行库(https://sourceforge.net/projects/boofcv/files/v0.33.1/)：

​

有没有从命令行运行的简单方法，我希望是这样的：

java -jar boofcv-recognition-0.33.1.jar -inputQRCodeImagePath [path to local image with QR code]

然后在命令行中获得二维码编码的文本输出，我可以进一步处理。

提前感谢！

这个特性是几个月前添加的。下载BoofApplications，然后执行以下步骤：

解压缩BoofApplications.zip

• cd BoofApplications

• java -jar applications.jar BatchScanQrCodes

的

这将打印出帮助。要在路径中的所有目录中扫描二维码，请执行以下操作：

java -jar applications.jar BatchScanQrCodes --Recursive -i path/to/input -o path/to/output

每50个文件它会打印出扫描的文件数。花了不到一分钟的时间扫描了整个测试集的二维码562个图像。然后，您将拥有一个如下所示的文件：
