[0003] The current scoring method for students’ experimental operation is that the invigilator observes the whole process of the experimental operation of the candidates in the examination room. However, there are many candidates in the experimental examination, and it is difficult for the invigilator to observe the details of the experimental operation of multiple candidates at the same time.
In order to improve the accuracy of the judgment of the experimental operation and reduce the number of candidates who are invigilated by the invigilator at the same time, it is necessary to increase the number of invigilators in the examination room, so that the determination of the experimental score will consume a lot of human resources

The embodiment of the invention provides a method and device for determining an experiment score, electronic equipment and a medium, and relates to the technical field of educational informatization,capable of reducing manpower resources consumed for determining the experiment score. According to the scheme of the embodiment of the invention, the method comprises the steps: obtaining the positionof a specified object included in each video frame from an operation video of a target experiment, and obtaining the state of the specified object included in each video frame from the operation video of the target experiment; determining a video frame corresponding to each operation step included in the target experiment from the video frames, wherein the video frame corresponding to each operation step is used for judging the score of the operation step; and determining the score of the operation step according to the position and / or state of the specified object in the video frame corresponding to each operation step, and calculating the score result of the target experiment based on the score of each operation step.
Description
technical field [0001] The invention relates to the technical field of educational informatization, in particular to a method, device, electronic equipment and medium for determining an experiment score. Background technique [0002] Experimental examinations are one of the important means to test students' mastery of knowledge. Experimental examinations include physical experiments and chemical experiments. Among them, physical experiments include: measuring resistance, measuring the electric power of small bulbs, verifying the imaging law of convex lenses, etc. Chemical experiments include: gas inspection, gas preparation, liquid measurement, etc. [0003] At present, the scoring method for students' experimental operation is that the invigilator observes the whole process of the experimental operation of the candidates in the examination room. However, there are many candidates in the experimental test, and it is difficult for the invigilator to observe the details of th...
