| 中文摘要: |
| 本文提出了一种基于单摆法测量管道内风速的方法,该方法区别于传统的风速测量方法,是通过管道支架水平和垂直方向的摄像头获取摆球的水平偏角和垂直偏角,进而利用空间几何关系计算空间角,从而计算管道内的风速.图像处理是该方法实现的重要组成部分,包括图像灰度化处理、二值化处理、边缘检测技术以及Hough变换等步骤.通过试验证明该方法可行,并且具有结构简单,精度高的特点. |

| This paper proposes a method for measuring the wind velocity in the pipe.It differentiates from traditional wind speed measurement method which obtains the pendulum ball’s horizontal and vertical angle through horizontal and vertical camera of the piping racks.By further taking use of the space geometry relation,the wind speed in pipes can also be calculated.Image processing is an important part of this method,including such procedures as image gray processing,binarization processing,edge detection technology and Hough transformation,etc.It proves that this method is feasible,simple in construction and high in precision. |
