MTK平台Camera人脸识别算法灵敏度参数

我是靠谱客的博主活力橘子，这篇文章主要介绍MTK平台Camera人脸识别算法灵敏度参数，现在分享给大家，希望可以做个参考。

当我们在使用MTK平台的相机时，如果默认使用MTK自带的人脸算法，可能会出现人脸识别不准确或者误识别等情况，这个问题MTK也提供了部分参数可供修改，我们接下来看一下应该如何修改。

（1）Log查看

先打开如下宏开关：

adb shell setprop vendor.debug.camera.log.ZoomRatioConverter 1
adb shell setprop vendor.debug.hal3av3.log 1
adb shell pkill camera*
adb logcat -G 20M

当算法识别到人脸数后Log中会有提示NumFace = x，如下：
