摘　　要：利用Delphi 7编写的紫外图像分析软件获取光斑面积大小,并基于最小二乘拟合曲线的原理,利用MATLAB软件Cftool(Curve Fitting Too1)工具箱实现对现场试验数据的拟合,从而得到紫外成像光斑面积与距离的拟合曲线方程,实现了光斑面积的量化分析,并在实际应用中得以证明,这对电气设备放电状态评估具有指导意义。This paper uses UV image analysis software written by Delphi 7 to calculate facular area and takes the advantage of Cftool （Curve Fitting Tool） toolbox of MATLAB to realize data fitting on the spot experiment based on the least squares fitting curve principle, obtains the fitting curve equation about UV imaging faeular area and distance to realize facular area quantitative analysis, and verify it in practical application, which has guiding significance in Electrical equipment discharge condition estimating.
