面向机器阅读的地图名称注记类别识别方法

Identification Method of Map Name Annotation Category for Machine Reading

  • 摘要: 地图在人们的生产生活中发挥着重要作用,地图注记中蕴含大量信息,识别地图名称注记类别对未来计算机阅读地图以及进一步绘制地图具有重大意义。近年来,热门的深度学习技术尤其是卷积神经网络对解决图像分类问题具有良好效果,使用训练集对卷积神经网络进行训练,神经网络模型可以提取出数据集图片中的特征,并不断调整模型参数直到训练完成。以谷歌的开源框架TensorFlow作为实验的深度学习平台,对多部地图集的多份注记数据集进行智能分类研究,从地图集中人工获取注记图片作为样本数据集,构建卷积神经网络模型并尝试混合训练和分开训练两种方式。实验表明,混合训练方式获得的模型表现更加出色。

     

    Abstract: Maps play an important role in people's production and life. There is a lot of information in annotations. Identifying map name annotation categories is of great significance for computer reading maps and further drawing maps in the future. Recently, popular deep learning technologies, especially convolutional neural networks, have a good effect on solving image classification problems. Training sets are used to train deep neural networks, and deep neural networks can extract the features of the data set pictures themselves and continue to adjust model parameters until the training is completed. This paper uses Google's open source framework TensorFlow as the experimental deep learning platform to conduct intelligent classification research on multiple annotation datasets of multiple Atlases. Manually obtain annotation images from the Atlas as sample datasets to construct a convolutional neural network model and try to use two methods of mixed training and separate training to train the models. Experiments show that the model obtained by the mixed training method performs better.
