Embodiment 1
[0073] image 3 is a schematic flow chart of the method for creating an eye template provided by this embodiment, such as image 3 As shown, when creating the eye template, step S301 is first performed to extract the face image of the current frame.
[0074] The face image of the current frame is acquired by using the face detection method in the prior art.
[0075] Step S302, determining the eye region of the face image of the current frame through simple region division.
[0076] In this embodiment, the face image of the current frame is described as a square image, and the simple area division can be assuming that the side length of the face area is 1 (the unit is the length unit), please refer to Figure 4 ,Such as Figure 4As shown, assume that the coordinate origin (0,0) is the upper left corner of the face area, starting from the origin, the horizontal direction to the right is the X direction, and starting from the origin, the vertical downward direction is the Y di...
Embodiment 2
[0121] This embodiment is a specific embodiment based on the technical solution of the detection method of the human eye state. In this embodiment, by judging whether the left eye and the right eye are blinking respectively, it is detected whether the eye state is in the eye-open state or blinking. state.
[0122] Such as Figure 7 As shown, step S701 is firstly executed to create a left-eye template and a right-eye template respectively.
[0123] The method for creating an eye template provided by the present invention can be used to create a left-eye template and a right-eye template respectively, which will not be repeated here.
[0124] Step S702 is executed to determine whether the face detection is successful.
[0125] After creating the eye template, when starting to detect the eye state, you need to perform face detection first to obtain the eye area to be detected. In this step, if it is judged that the face detection fails, create an eye-opening template according ...
