Disclosed in embodiments of the present invention are a personnel state detection method and apparatus based on eyelid feature information. The method comprises: obtaining a face image containing a face of a target person; detecting two-dimensional position information of a face feature point from the face image; constructing a target three-dimensional face model based on a preset three-dimensional face model; determining projection position information of an eyelid space point at a specified position in the face image based on a projection matrix; determining the current opening and closing length between upper and lower eyelids based on the two-dimensional position information of the eyelid feature point at a position corresponding to the specified position in the face image, three-dimensional position information of the eyelid space point at the specified position, and projection position information; and determining the current state of the target person based on the current opening and closing length, so as to determine the eyelid feature information of the human eyes. The accuracy of the detection result of the opening and closing state of the human eyes is improved by using the eyelid feature information, and the accuracy of the detection result of the current state of the person is improved.
