It also wastes the teacher's research time. In order to reduce such unnecessary duplication of effort, asystem using VB technique plete results entry have been designed. Firstly, the original experiment report paper must bemodified slightly. Secondly, the images of paper lab reports are obtained by using the USB camera for system identification. Finally, the resulting digital information achieved is written into an Excel words: USB camera; college physics experiment result; entering system近年来,由于高校招生人数大量上升,使得在校大学生越来越多,特别是理工科学生占了大多数,而几乎所有的理工科学生都会有一门课程,就是大学物理实验。但是学校的物理实验教师只有几个,要负责全校所有院系的物理实验课,课后还要进行实验报告的收缴、批改和分数录入工作,这让物理实验教师感觉分身乏术,其中分数录入工
