摘　　要：设计并实现了一种智能音乐播放控制系统,可根据人脸表情识别结果选择合适的播放音乐。硬件系统由PYNQ_Z2开发板、摄像头、HDMI显示屏、音箱组成;软件系统在ARM+FPGA的核心芯片上通过Haar特征与Adaboost算法进行人脸检测,通过LDA与K近邻算法完成表情识别。利用置信度对表情识别结果做二次分类,并利用PID控制算法对置信度进行调节,提高不均匀光照时系统的鲁棒性。本系统延迟小、鲁棒性强、人机交互丰富,具有较为广泛的应用场景。An intelligent music playback control system,which can select the appropriate music to play according to the facial expression recognition result,is designed.The hardware system consists of PYNQ_Z2 development board,camera,HDMI display and audio.The software system performs face detection on the core chip of ARM+FPGA through Haar feature and Adaboost algorithm,and realizes expression recognition through LDA and k-nearest nearest neighbor algorithm.The expression recognition results are sub-classified by confidence,and the PID control algorithm is used to adjust the confidence to improve the robustness of the system during uneven illumination.The system has low delay,strong robustness and rich human-computer interaction,and has a wide range of application scenarios.
