| 摘要: |
| 采用计算机图像视觉的方法，利用MATLAB强大的图像处理功能，对拍摄的喷雾图像进行了去噪及二值化等初步处理，提取其边缘图像，对不规则的喷雾图像边缘进行了最小二乘拟合，得到了最近似于该边缘的2条相交直线，二者夹角即为所要求的雾化角。根据最小二乘拟合的定义，该方法的误差平方和最小，从而使雾化角的确定精度大大提高。 |

| Abstract: |
| This paper introduces a computer image vision method.Taking advantage of the powerful image processing function in MATLAB,the atomization image taken by a video camera was pre-processed with de-noise processing and binaryzation processing.And the image edges were extracted.Then the irregular edges of atomization image were fitted to regression lines using the least square fitting function.Two intersected straight lines most approximative to the edges were obtained.The angle between the two lines was just the wanted atomization angle.According to the definition of least square fit,its error sum of squares is the least.Thus,the precision for determining the atomization angle is improved greatly. |
