基于PBL的光电图像处理课程知识图谱建设研究

Research on the Construction of a Knowledge Graph for the Optoelectronic Image Processing Course Based on Project-Based Learning

摘要: 针对光电图像处理课程中知识点分散、理论与实践衔接不足及项目教学路径不清晰等问题，本文提出一种融合PBL教学模式与知识图谱技术的课程建设方法。结合课程内容体系与项目式学习需求，构建了包括项目任务设计、知识抽取与分类、关系建模、知识图谱构建与可视化、学习反馈与知识迭代在内的五阶段知识图谱构建流程。在此基础上，设计“项目需求–所需理论–适配工具–实施环节–考核标准”一体化PBL教学框架，并以“基于机器视觉的太阳能电池片缺陷检测”项目为例，给出面向PBL教学的多视角知识图谱可视化表达方案。本文研究可为光电图像处理课程的知识组织、项目化教学设计及教学资源整合提供参考，并为工程类课程教学改革提供一种可借鉴的实现路径。

Abstract: To address the problems of fragmented knowledge points, insufficient integration between theory and practice, and unclear pathways for project-based teaching in the Optoelectronic Image Processing course, this paper proposes a curriculum construction method integrating the PBL teaching model with knowledge graph technology. Based on the course content system and the requirements of project-based learning, a five-stage process for knowledge graph construction is established, including project task design, knowledge extraction and classification, relationship modeling, knowledge graph construction and visualization, and learning feedback and knowledge iteration. On this basis, an integrated PBL teaching framework is designed, covering project requirements, required theories, applicable tools, implementation procedures, and assessment criteria. Furthermore, taking the project of solar cell defect detection based on machine vision as an example, a multi-perspective knowledge graph visualization scheme for PBL teaching is presented. This study can provide a reference for knowledge organization, project-based instructional design, and teaching resource integration in the Optoelectronic Image Processing course, and offers a feasible path for the reform of engineering education.
