The invention relates to the technical field of robots, in particular to a humanoid robot face bionic driving structure with high-degree-of-freedom expression control, an eyebrow module and an eye module of the humanoid robot face bionic driving structure are both arranged on a fixing frame, a mouth module is arranged below the fixing frame, assembly is more convenient and faster, the space utilization rate is higher, and the maintenance cost is lower. A first movement device, a second movement device and a third movement device in the eye module are vertically and horizontally arranged in a staggered mode. The eyeballs are fixedly connected with the third movement device and can be controlled to rotate up and down and left and right. Eye corner connecting positions on one side of the lower eyelid and one side of the upper eyelid are rotationally connected to the supporting seat, and an eye corner on the other side of the lower eyelid is rotationally connected with an eye corner on the other side of the upper eyelid. The first movement device and the second movement device are matched to drive the upper eyelids and the lower eyelids to move up and down so as to open or close the eyes, so that the structural movement smoothness of the eyes is higher, and the movement of the eyes is more natural and vivid.

The invention provides an inflatable doll with a light effect, which comprises eyes and a light-emitting device, the light-emitting device is specifically arranged at the eyes, the light-emitting device comprises a plurality of light sources which are vertically arranged, the light sources are firstly extinguished one by one from top to bottom and then are lightened one by one from bottom to top, the action that the eyes of the inflatable doll are opened after being closed is simulated, and the light-emitting device is used for emitting light. Therefore, a blinking lamp effect is formed, and the attention of people can be attracted.

The application provides a dim environment closed-eye detection method and system, and belongs to the technical field of computer vision detection.The dim environment closed-eye detection method is characterized in that the following steps are included: setting a lower threshold value and an upper threshold value, wherein the lower threshold value and the upper threshold value are both positive numbers, and the lower threshold value is smaller than the upper threshold value; receiving a video frame, calculating an EAR according to eye key point coordinate information; judging the EAR according to a double threshold method, and when a plurality of continuous frames meet the set condition, the closed-eye state is determined, wherein the execution method of the double threshold method includes: judging the EAR value, if the EAR value is smaller than the lower threshold value, starting counting, and if the EAR value is smaller than the upper threshold value, the number of times is accumulated, if the EAR value is not smaller than the upper threshold value, stopping and resetting the counting, and when the number of times reaches the set threshold number of times, the closed-eye state is determined.The application has the beneficial effect that the closed-eye state can be stably and accurately detected in a dim environment such as a mine, thereby providing support for a fatigue driving detection system.

Abstract Method (700), implemented by a data-processing device (202), for aligning a face (103a, 301) of an individual (103) in an image (I700), the method (700) comprising the following steps: (a) detecting (701), in an image (I700) of the face (103a, 301) of an individual (103), the positions of a left eye (503), of a right eye (504), of a midpoint (505) between the right eye (504) and left eye (503), and of a midpoint (506) of the mouth (501); (b) applying (702) a first geometric transformation (TG1) so that the positions of the midpoint (505) between the left eye (503) and right eye (504) and of the midpoint (506) of the mouth (501) coincide with reference points (801, 802); (c) applying (703) a second geometric transformation (TG2) so that the position of the closest eye (503, 504) in the depth of the image (I700) coincides with the position of a vertical reference line (901, 902).
