In childhood education, there are lessons that teach children to perform basic movements, such as basic grasping movements that teach children to grasp a glass ball in front of the eye. Although this action is simple, it is not easy for children to grasp, and some children cannot grasp the glass ball successfully, but cannot grasp the glass ball permanently, and throw the glass ball away.
In one embodiment, the determining whether the child has completed the predetermined job task according to the child job action video includes:
determining a child and a teaching tool in the video by adopting a target detection algorithm for any image frame in the child operation action video;
wherein, the teaching tool can be a glass ball.
Determining the coordinate value of the central point of the marking frame of the child face and the coordinate value of the central point of the marking frame of the teaching tool;
and determining whether the child completes the operation task according to the coordinate value of the central point of the marking frame of the child face and the coordinate value of the central point of the marking frame of the teaching tool.
In one embodiment, the determining whether the child completes the task according to the coordinate value of the center point of the mark frame of the child face and the coordinate value of the center point of the mark frame of the teaching tool includes:
the coordinate values of the central point of the marking frame of the child face comprise an abscissa and an ordinate;
the coordinate values of the central point of the marking frame of the teaching tool comprise an abscissa and an ordinate;
calculating a difference value N1 between the vertical coordinate of the mark frame of the child face and the vertical coordinate of the mark frame of the teaching tool;
judging whether the difference value N1 is less than or equal to a preset vertical coordinate difference value threshold value or not; if yes, calculating a difference value N2 between the abscissa of the marking frame of the child face and the abscissa of the marking frame of the teaching tool;
judging whether the difference value N2 is less than or equal to a preset horizontal coordinate difference value threshold value or not; if so, it is determined that the child completed the action task.
The vertical coordinate difference threshold and the horizontal coordinate difference threshold can be flexibly set.
In one embodiment, if the difference value N1 is less than or equal to a predetermined vertical coordinate difference threshold value and the difference value N2 is less than or equal to a predetermined horizontal coordinate difference threshold value; determining that the action is qualified and the score is a first grade; if the difference value N1 is greater than a predetermined vertical coordinate difference threshold value or if the difference value N2 is greater than a predetermined horizontal coordinate difference threshold value, the action is determined to be disqualified and the performance is the second grade.
The above-mentioned horizontal coordinate difference threshold may be flexibly set according to actual situations, and may be set as the length of the arm of the child, that is, if the difference N1 is greater than the difference threshold, it is determined that the child has not successfully grasped the object.
The difference threshold of the vertical coordinate can be flexibly set according to the actual situation, and can be set as the vertical distance from the center point of the face of the child to the longitudinal direction of the arm. If the difference N2 is greater than the difference threshold, it is determined that the child has not caught the object in front.
If the difference value N1 is less than or equal to a predetermined ordinate difference threshold value and the difference value N2 is less than or equal to a predetermined abscissa difference threshold value; determining that the child grabs the object in front of the child and the action is qualified;
further, it is also possible to count the time when the child grabs the object, that is, calculate the duration T1 during which the difference N1 is less than or equal to the predetermined vertical coordinate difference threshold and the difference N2 is less than or equal to the predetermined horizontal coordinate difference threshold. The longer the time, the longer the object held, indicating that the child grabbed, the higher the performance.
Therefore, in one embodiment, the capture time threshold T2 may be set, and when T1 is greater than T2, the action is determined to be acceptable.
In one embodiment, the specific action of the child grasping the glass ball can be identified, for example, the action of pinching the ball with the thumb and forefinger. The action can exercise the flexibility of the fingers of the children and improve the coordination of the actions of the children.
Specifically, the parents upload the shot video of the action of grabbing the glass ball by the children to the server.
In the server, for any image frame in the video, the image in the image frame is identified by adopting an image identification model which is trained in advance, and the identification result is output, wherein the result is yes or no.
If the motion in the image frame is the motion of pinching the ball by the thumb and the index finger, the output result is yes, and if the motion is not the motion of pinching the ball by the thumb and the index finger, the output result is no.
