The invention relates to a facial expression recognition method and system based on AI recognition. The method comprises the following steps: preprocessing a to-be-detected image to obtain a to-be-detected preprocessed image; performing facial expression recognition by using the to-be-detected preprocessed image to obtain a facial expression recognition result, and performing background denoising processing by using the to-be-detected image to obtain an initial to-be-detected image; and performing image graying processing by using the initial to-be-detected image to obtain a to-be-detected pre-processed image, processing the selected neural network based on an actual application scene, and performing interference removal processing on the acquired image, so that the influence of other data on the recognition process is avoided, the recognition rate is improved, and the recognition speed is increased. 本发明涉及一种基于AI识别的面部表情识别方法与系统，包括：利用待检测图像进行预处理得到待检测预处理图像；利用所述待检测预处理图像进行面部表情识别得到面部表情识别结果，利用待检测图像进行背景去噪处理得到初始待检测图像；利用
