Embodiment 1

[0049] see Figure 1~3 , an intelligent scoring system for plane mirror imaging experiments, the system includes

[0050] Image Acquisition Module: Obtain the image of the current experimental table from the top camera, decode the video according to the relevant codec protocol of the Haikang camera, and obtain image information that can be used for image processing. The size of the obtained normal image information will be changed from 2560 *1520 is scaled to 832*832 as the input of the deep detection network;

[0051] Image detection module: mainly composed of two parts, namely the YOLOv5 target detection network and the FLD line segment detection algorithm that can intelligently identify each experimental device in the experimental process;

[0052] Post-detection processing module: reprocess the detected line segment to determine the required line segment. According to the requirements of some scoring points, some line segments need to be stored in the form of pixels where...

Embodiment 2

[0070] see figure 2 , a method for using an intelligent scoring system for plane mirror imaging experiments, the system includes the following steps

[0071] Step 1. Camera video collection on the top of the experimental table: Obtain the operation video of the plane mirror imaging experiment from the top shooting angle of the experimental table, and obtain the information of each device itself and related operation actions;

[0072] Step 2. Video decoding: Decode the video of the plane mirror imaging experiment operation into a picture, and prepare to input it to the detection and recognition model after preprocessing;

[0073] Step 3. Target detection and target reprocessing: transfer the acquired pictures to the trained YOLOv5 network for real-time target detection; filter the detected target information and perform reprocessing by means of line segment detection and other means;

[0074] Step 4. Image target analysis and score judgment: Combine the processed target infor...

Abstract

The invention discloses an intelligent assignment system for a plane mirror imaging experiment. The system comprises an image acquisition module, an image detection module, a detection post-processing module, an experiment specification and assignment judgment module and a display module. The system comprises the steps of video collection of the top shooting camera of the experiment table, video decoding, target detection and target reprocessing, picture target analysis and score judgment, and experiment result display. The system has the beneficial effects that according to the score points given by the examination questions, the video streams obtained by the students in the process of operating the plane mirror imaging experiment are analyzed in time through a real-time detection technology, so that the related score points are scored correctly, then intelligent score scoring of the experiment operation is realized, and the pressure of educational resources can be well relieved.

Description

technical field [0001] The invention relates to a scoring system, in particular to an intelligent scoring system for plane mirror imaging experiments, and belongs to the technical field of automatic scoring for junior high school physics experiment examinations. Background technique [0002] The plane mirror imaging experiment is a part of the junior high school physics experiment, and it is one of the test questions for the high school entrance examination. Due to the real-time nature of scoring in the operation experiment test, people's attention is limited to a certain extent. Each candidate needs to be assigned a scoring teacher during the exam, which poses a great challenge to the existing teacher resources. If the experimental operation can be judged intelligently, the pressure on educational resources can be well relieved. [0003] At present, there is no solution for the imaging experiment of plane mirrors in the market. The video stream obtained during the experi...
