摘  要:为了提高数显仪表的识别率,设计了一种传统图像处理方法和深度学习技术相结合的算法,即一种基于改进的卷积神经网络的数显仪表识别算法。首先通过传统图像处理技术对图像进行图像预处理、字符分割等操作,然后由基于注意机制的卷积神经网络算法对字符进行识别。实验结果表明,该方法不仅有效提高了字符的准确率,字符识别率高达98.5%,还提高了网络的收敛速度。该方法基本可以满足各种数显仪表的识别,能够满足实际应用的需求。In order to improve the recognition rate of digital display instruments, an algorithm combining traditional image processing method and deep learning technology is designed, that is, an algorithm for digital display instrument recognition based on an improved convolutional neural network. Firstly, the traditional image processing technology is used to perform image preprocessing, character segmentation and other operations, and then the characters are recognized by the convolutional neural network algorithm based on the attention mechanism. The experimental results show that this method not only improves the character accuracy effectively, the character recognition rate is up to 98.5%, but also improves the convergence speed of the network. This method can basically meet the recognition of various digital display instruments and meet the requirements of practical application.
