OpenCVForUnreal

how to use face/body recognize and more in unreal engine

Attention

1. You need to manually download the model yourself, and place it under the directory "OpenCVForUnrealOpenCVForUnrealConfig"
2. The latest version has modified the HiKVisonActor to OpenCVForUnrealActor , which may have had a slight impact on previous projects.

Description

1. Currently all compilations are OK on UE5.2,and you should download pre-traning-model from https://github.com/spmallick/learnopencv/tree/master/FaceDetectionComparison/models
2. UE4 uses the OpenCV library plugin
3. UE4 Multithreaded FRunnable Usage
4. UE4 asynchronous calls
5. Use DNN deep neural network face recognition, gender, age, object detection, etc
6. Comparison of various face recognition models
7. Mat image to UE4 UTexture2D picture, Mat picture cropping, etc
8. Adjust the brightness of the picture, for example, the picture is dark at night, you can adjust it
9. The Python version is used for separate identification, if UE4 does identification and affects other performance, it can be communicated separately through Python scripts
10. If you need to use version 4.27, use the tag's version,

中文

1. 目前已经支持UE5.2，如果需要使用4.27版本，请使用tag版本
2. UE4使用OpenCV库插件，OpenCV版本已经升级位4.7.0
3. UE4多线程FRunnable使用
4. UE4异步调用
5. 使用DNN深度神经网络人脸识别，性别，年龄，对象检测等
6. 各种人脸识别模型对比
7. Mat 图片转UE4的UTexture2D图片Mat图片裁切等
8. 调整图片亮度，比如晚上图片比较暗，可以调整
9. Python版本是用做单独识别，如果UE4里面做识别影响其他性能，可以单独通过Python脚本来通信
10. 需要自己手动下载模型放在目录OpenCVForUnreal\OpenCVForUnreal\Config下面
11. 最新版本已经将HiKVisonActor修改OpenCVForUnrealActor,这或许对之前项目有一点影响。
