Study on axial thermal disturbance imaging in vision measurement

摘要: 为研究热源干扰图像成像引发的图像畸变、模糊等失真问题，利用图像的特征点平均畸变位移、峰值信噪比、均方误差和互相关系数来评价热源轴向位移条件下成像图像的畸变程度、模糊程度以及总相似程度，得到热干扰成像变化与热源轴向位置之间的规律。实验表明，当热源在成像系统和成像目标之间作轴向运动时，其距离成像系统越近，成像的畸变程度、模糊程度以及失真程度越大，在D=300 mm处最大平均畸变位移达2.765 3 mm；当热源靠近成像目标时，成像图像的畸变程度、模糊程度以及失真程度降低，在D=0 mm处平均畸变位移减小至0.810 2 mm。Abstract: In order to study the image distortion and blurring caused by the heat source interference, the level of distortion, blurring and total similarity for the heat source axial displacement imaging were evaluated through using the feature points' average distortion displacement, peak signal to noise ratio, mean squared error and cross correlation coefficient. Furthermore, the correlative discipline between thermal disturbance imaging changes and heat source axial position was gained. Experiment shows that for the heat source axially moving between imaging system and imaging target, the level of distortion, blurring and imaging fault will be worse as the heat source comes closer to the imaging system, and the maximum average distortion displacement is 2.765 3 mm at D=300 mm; as the heat source comes closer to the imaging target, the level of distortion, blurring and imaging fault will be better, and the average distortion displacement decreases to 0.810 2 mm at D=0 mm.
