基于直方图相似度度量的中央空调风管附尘度检测

对于主从控制中央空调清洁机器人，操作人员依据视频很容易就可判断出风管是否清扫干净。在机器人自主清洗中央空调风管时，为了能够使机器人识别管道内灰尘附着程度，文章采用了直方图相似度作为清洁机器人自动判断管道附尘度和清洁与否的标准。文章给出了相关的原理和算法，并进行了试验验证，结果表明该方法具有快速性、实时性和准确性等特点。

Dust Thickness Detection for Air-Duct of Central Air-Conditioning Based on Histogram Similarity Measurement

For the master-slave control central air-conditioning cleaning robot, the operator can easily judge the cleanness of the air-duct according by the video. The paper adopts the histogram similarity as a standard such that the cleaning robot can autonomously judge the dust thickness. The principle and algorithm are proposed in the article. The test result indicates that the method is rapid, real-time and accurate.
