摘要
施工扬尘是现今影响城市生态环境的关键因素之一。因施工场地规模大、施工环节繁琐,影响施工扬尘污染监测,提出基于GPRS的施工扬尘污染远程监测方法研究。引入GPRS技术搭建监测图像数据传输网络结构,并确定数据包格式,应用大律法分割处理监测图像,以背景分割处理后的监测图像为依据,提取监测图像特征值,通过朴素贝叶斯分类器分类监测图像,从而实现施工扬尘污染的远程监测与识别。实验数据显示:应用提出方法获得的监测图像传输时间更短,监测图像正确分类比更大,充分证实了提出方法扬尘污染远程监测效果更佳,适合大力推广与应用。
Construction dust is one of the key factors affecting the urban ecological environment. Due to the large scale of the construction site and the cumbersome construction links, the monitoring of construction dust pollution is affected. A research on remote monitoring method of construction dust pollution based on GPRS is proposed to solve the problem. GPRS technology is introduced to build the monitoring image data transmission network structure in order to determine the data packet format, apply big law segmentation to process the monitoring image, and extract the characteristic value of the monitoring image based on the monitoring image after background segmentation. The study classified the monitoring image through naive Bayesian classifier, so as to realize the remote monitoring and identification of construction dust pollution. The experimental data show that the transmission time of the monitoring image obtained by the proposed method is shorter and the correct classification ratio of the monitoring image is greater, which fully proves that the proposed method has better effect on dust pollution remote monitoring and is suitable for vigorous promotion and application.
