Embodiment Construction

[0110] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with aspects of the present application as recited in the appended claims.

[0111]In order to automatically identify the connection relationship between the various instruments, a new set of wires and instruments for electrical experiments is designed in this embodiment. For wires, the two ends of the wire are terminals, and each terminal is provided with a label. The labels at both ends of the same wire are the same, but the labels set on different wires are di...

Abstract

The invention relates to a scoring method and a device for an electrical experiment, and belongs to the field of video monitoring. The method comprises the steps that N circuit diagrams correspondingto circuits are acquired according to an operation video of an electrical experiment operated by a to-be-scored person, and the N circuit diagrams are acquired according to continuous N frames of video pictures in the operation video; for any circuit diagram, the circuit diagram is subjected to splitting to obtain at least one branch circuit included in the circuit diagram, and instruments on eachbranch circuit are connected in series, wherein the at least one branch circuit comprises a plurality of branch circuits between two adjacent circuit intersection points in any one circuit diagram and a branch circuit between a power supply positive electrode and a power supply negative electrode in any one circuit diagram; the score of each scoring point of the electrical experiment can be determined according to at least one branch included in each circuit diagram and the N frames of video pictures; and the score of the electrical experiment can be calculated according to the score of eachscoring point included in the electrical experiment. According to the invention, the circuit scoring efficiency can be improved.

Description

[0001] This application is a divisional application for an invention patent with the application number 201910319758.4, the application date is April 19, 2019, and the invention name is "a scoring method and device for electrical experiments". technical field [0002] This application relates to the field of video surveillance, in particular to a scoring method and device for electrical experiments. Background technique [0003] Physics is a course in middle school education, physics experiment is an important teaching content of physics teaching, and electrical experiment is an important teaching content of physics experiment. When doing electrical experiments, students will use wires to connect different instruments to form circuits. These instruments can be power supplies, resistors, light bulbs, switches, voltmeters, ammeters, and sliding resistors. [0004] After the students connect the circuit, the teacher detects the connection relationship between the various instru...
