A method for acquiring a gaze point of an eye and a test system are provided. In the method operated in a computing device, position of a human face is frame-by-frame determined from continuous frames captured by a camera. Image features of the face are extracted for obtaining the positions of two eyes. A deep-learning model is operated to calculate confidences of multiple feature points of the eyes. One of the eyes is selected based on total confidences of the two eyes. User calibration is performed for eliminating an offset between the gaze point and a target point due to individual error. Therefore, a gazing direction is computed.

In a second stage, the teacher model performs prediction on unlabeled data and generates pseudo labels according to a prediction result. The student model learns labeled data and unlabeled data based on the pseudo labels. A soft label filter is used to filter for obtaining high-quality pseudo labels, a positive sample loss function is used to eliminate a problem of incorrect model convergence due to the pseudo labels with incomplete information, and the parameters of the student model are updated via a backward propagation process. In a third stage, the parameters of the student model are transferred to the teacher model through an exponential moving average operation, so that the teacher model and the student model are under a same architecture.
