摘　　要：该设计实现了一种新型的试卷分数求和器,利用摄像头直接获取手写试卷分数栏信息,实现分数求和功能且能够自动适应不同的求分栏数目。求和器首先利用摄像头对试卷实时采样并对其进行二值化、图像定位和图像分割等预处理,然后利用BP神经网络对分割出的字符进行数字识别,最后将识别出的数字加和显示在GUI界面中。实验表明,该求和器能够以较高概率实现对手写试卷分数的自动求和,具有较大的应用前景。A novel score summer system for handwritten test paper is proposed in the paper. The summer system acquires the score information of handwritten test paper by digital camera,and then can automatically output the summation and can adap itself to different number of scorelines. The summer firstly captures the image of test paper by digital camera and then preprocess the image including binaryzation,image positioning and segmentation. The BP neural network is employed to accomplish the score value recognition based on the preprocessed result,and then the summation is displayed on GUI interface. The experiments based on real system show the proposed score summer system can implement automatic summation of handwritten test paper in high probability.
