With the continuous progress of computer technology and artificial intelligence research, Facial Expression Recognition (FER) is the core problem of artificial psychology and emotion research, and it is also an important direction of human-computer interaction technology. This paper discusses the design of the expression recognition system in depth, especially the improvement of the feature extraction-related algorithm, in order to improve the accuracy of expression recognition and ultimately achieve the goal of the expression recognition system. This paper uses a method based on the improved AdaBoost algorithm and Haar features to improve the accuracy and speed of face detection. Comparing the training time and accuracy rate of the algorithm before and after

In order to reduce the error and improve the calibration accuracy, the calibration parameters obtained by the solution are nonlinear iteratively based on the plane checkerboard calibration method to minimize the reprojection error and find the global optimal solution. After analyzing the theoretical imaging model of the camera and studying the nonlinear camera imaging model after introducing distortion parameters, the camera transformation matrix and the parameters in the camera are solved, and finally the calibration results are optimized. The experimental results show that the mean calibration error of this method is 0.1402 and the standard deviation is 0.0207, which has higher accuracy and better stability than the traditional calibration method and has certain engineering practical significance.
