Optionally, if the position difference is greater than a preset threshold, it indicates that the measured position of the target measuring point is wrong under the target assessment task, at this time, an assessment result that the assessment does not pass can be directly obtained according to a preset assessment algorithm, so as to improve the assessment efficiency, and of course, according to an actual application scenario, the assessment can be further refined to obtain the assessment score of each operation, so that an assessment user knows the specific assessment condition.
For example, if the measurement position of the target measurement point under the target assessment task is correct, the assessment score of the operation can be obtained as 50 points according to a preset assessment algorithm, if the measurement state of the multimeter under the target assessment task is correct, the assessment score of the operation can be obtained as 50 points according to the preset assessment algorithm, it can be understood that if both operations of the assessment user under the target assessment task are correct, the assessment score of the assessment user is 100 points, which indicates that the assessment user passes the assessment, otherwise, indicates that the assessment user fails the assessment. Of course, the actual evaluation method is not limited to this, and the evaluation may be performed according to the grade, and the present application is not limited thereto.
Of course, it should be noted that the execution sequence of step S401 and step S402 is not limited herein, and may be flexibly adjusted according to the actual application scenario.
