| 摘 要: 为了防止计算器数字的误读，本文采用了一种基于穿线法的识别数字装置对计算器数字进行识别。识别 功能由图像预处理、二值化、形态学处理、图像分割、穿线法找出数字特征这几大步骤构成。穿线法是识别数字的关 键，通过实验表明，该识别方法的识别率可以达到100%，配有该识别数字装置的计算器可以有效地提高数字的识别精 度，降低误识率。 |

| Abstract: In order to prevent the misreading of the calculator numbers,this paper uses a device based on OpenCV to identify the calculator numbers.The recognition function consists of image preprocessing,binarization,morphological processing,image segmentation,and threading to find the digital features,in which the threading method is the key to identifying numbers.Experiments show that the identification rate of the method can reach 100%,and the calculator equipped with the identification device can effectively increase the accuracy and reduce the rate of misreading. |
