我正在使用Firebase ML从图像获取文本。它可以很好地处理图像。但是问题是从图像中获取了特定的文本。
我想从下面3张图像中获取文本值。
https://i.stack.imgur.com/vkFxk.jpg
https://i.stack.imgur.com/GrpTW.jpg
https://i.stack.imgur.com/CSbJ3.jpg
所需的输出（*为第一张图像）：
序列号：350813（可以是字母数字）
颜色印象数：487
黑人印象：21116
彩色大印象数：4
总印象数：21653
但是我坚持要从这些图像中获得适当的价值。 Firebase ML套件在不同的时间为我提供了不同的格式。因此，我无法放置任何正则表达式来获得准确的结果。
那么，有人可以帮助我如何从这些图像中获得正确的结果吗？
我没有发布所有代码。这是我的主要方法，将在从图像中捕获数据后运行。
