使用arcore和ml kit firebase检测到二维码后，如何使用增强现实来更改二维码的颜色

Question

我需要开发一个允许我扫描条形码的 android 应用程序，如果该条形码保存在预定义的列表中，请使用 arcore 和 ml 套件将条形码的颜色更改为绿色，如果不更改为红色

Answer 1

The easiest solution that can be developed in no time is to add a green/red rectangle around the QR code. Otherwise you would have to update the screen pixels where you have the black (or white as you wish) and replace them with green/red pixels. From the developement point of view the second solution is far more complex than the other one, considering the techology that you are using.
