摘　　要：对气泡幕中气泡粒子的识别及尺寸计算进行了分析,详细介绍了将延伸率、紧凑率、似圆程度和惯性因子作为主要因素的特征向量法对气泡粒子的识别和计算。由分析可知,基于激光切片的技术可以先对图像进行二维分析,然后将所获得的数据叠加进而实现三维分析,更有助于气泡幕的探测。This paper analyzes the identification and size calculation of bubble particles in bubble curtain,and introduces the identification and calculation of bubble particles in detail by the feature vector method,which takes the elongation rate,compactness rate,roundness degree and inertia factor as main factors.The results show that the technique based on laser slice can firstly analyze the image in two dimensions,and then overlay the obtained data to realize three-dimensional analysis,which is more helpful for bubble curtain detection.
