基于图像处理的便携式客观题阅卷系统研究

Research on Portable Objective Question Marking System Based on Image Processing

人工评分与统计的方式难以提高阅卷效率,对教师和科研人员的时间造成大量浪费。而光标阅读机,其成本高昂也不能普遍使用。鉴于手持智能设备的普及和高效完成阅卷的需求,本文采用基于手持设备的图像识别技术进行答题卡采集、分析、识别和评分统计,构建一种便携设备评分系统,供教师和科研人员使用。本文研究内容既有有充分的理论基础又有实际应用价值。

The manual marking and statistics approach makes it difficult to improve the efficiency of marking and causes a lot of waste of time for teachers and researchers.As for the cursor readers,their high cost also cannot be commonly used.In view of the popularity of handheld smart devices and the need for efficient completion of marking,this paper uses image recognition technology based on handheld devices for answer card collection,analysis,recognition and marking statistics to build a portable device marking system for teachers and researchers to use.The research content of this paper has both sufficient theoretical basis and practical application value.
