The comparison score characterizes the degree of similarity of motion between the scoring video and the control video.
The preset difference represents the highest difference between the comparison score value and the lowest examination score, when the comparison difference is larger than the preset difference, the terminal server needs to mark the scoring video, which indicates that the score of the scoring video is too low by a commentator teacher, so that the scoring evaluation needs to be carried out again on the marked scoring video. When the comparison difference is equal to or smaller than the preset difference, the terminal server does not need to mark the scoring video, and the score of the scoring video is normal by a comment teacher, so that the scoring evaluation of the marking scoring video is not needed again.
The preset difference value mentioned here can be set manually in advance, and can be set to any value, in this embodiment, 15 is preferred, which indicates that the difference between the comparison difference value and the preset difference value is 15 minutes, so as to indicate that the score of the score video by the panelist is at a normal value.
Here, in order to prevent the occurrence of aesthetic fatigue of the test taker, the comparison difference is the difference between the comparison score value and the lowest test score, and the comparison is not performed with respect to the highest score, because it is considered that the test taker can directly feel the score of the test taker through the subjective score of the individual, such as the overall test state of the test taker and the management of the expression during the test, and the like, and thus the score of the other test taker is not measured.
