acquiring an image of an object;
wherein the step of obtaining an image of the object further comprises, before the step of obtaining an image of the object:
it is determined whether the object is located in a preset area,
the device for acquiring the image of the object is generally a camera, the general object is a person, and the shooting distance of the camera is limited, so that whether the object is in a preset area or not, namely the position where the camera can shoot, needs to be judged first, or whether the area is in the preset area or not is judged through the shot picture or video.
When the object is located in a preset area, acquiring an image of the object;
when the object is positioned around the camera, the object can be accurately obtained through shooting, and the image of the object can be directly obtained;
when the object is located in the preset area, the image of the object is not acquired.
And when the object is positioned in a preset area, judging whether the object is in a working state, and when the object is in the working state, acquiring an image of the object.
The recognition that the object is in the working state may be an office table set at home, and when the object is seated on the office table, it may be determined that the object is in the working state.
When the object is in a motion state, obtaining motion information of the object;
judging whether the object is close to a preset barrier or not according to the motion information of the object, and sending out prompt information when the object is close to the preset barrier;
and when the object is not close to the preset barrier, no prompt message is sent.
Preset the barrier can be table corner edge or the sharp object etc. in the family, and when children were close to these sharp objects etc., in time send out prompt message, remind information can be for sending modes such as audio frequency of "colliding carefully" through the mode of pronunciation, avoid children to collide the sharp object, lead to injury scheduling problem.
And when the object is in a non-working state and a non-motion state, the camera continues to collect the object. The object may be watching television or doing other leisure at this time.
When the object is not at the position of the camera, the camera cannot shoot the image of the object.
Carrying out face recognition on the image to acquire a face in the image;
the method specifically comprises the following steps: based on YCbCr color space, a two-dimensional Gaussian distribution mathematical model based on skin color is established,
and combining the skin color similarity and the human face shape characteristic to perform face recognition on the image to acquire the face in the image.

counting the eye closing frequency of the facial features in a plurality of groups of images according to a PERCLOS algorithm to obtain a statistical result;
judging whether the statistical result exceeds a preset threshold value,
when the statistical result exceeds a preset threshold value, judging that the object is in a fatigue state;
and when the judgment object is in the fatigue state, broadcasting voice prompt and playing preset music. The preset music may be music selected by the subject.
And when the statistical result does not exceed a preset threshold value, judging that the object is in a non-fatigue state.
When the statistical result exceeds the blinking frequency of normal people, the fatigue state can be judged.
In order to improve the accuracy of fatigue state identification, correct information characteristic communication and comparison of a human body can be carried out in real time by utilizing a mobile network and a background database. The background database can further supplement and update the state characteristic information of the human body in the process of recognizing and collecting the human body state sample data by using the existing state image data set. The method ensures that the human body state can be accurately positioned to provide required built-in function assistance, reduces the probability of judging errors of the fatigue state of the object reminding based on information comparison and storage of the network, and adjusts the actual preset threshold value through the real-time mobile network, thereby improving the accuracy of fatigue state identification.
