分析CCD成像跟踪系统的组成及常用跟踪算法,针对激光干扰图像的特点,结合机器视觉中背景杂波的量化方法,提出一种基于小波能量与平方和根的图像尺度,并将其应用于激光干扰对成像跟踪性能的影响分析。该尺度利用小波能量尺度在成像跟踪系统方面以及平方和根尺度在目标局部对比度方面各自的优点,适用于激光干扰后跟踪算法性能的评估。激光视场内干扰与视场外干扰的实验结果表明,该尺度能够较好地反映激光干扰图像对于CCD成像跟踪算法性能的影响,初步验证了尺度的有效性。
Based on the characteristics of laser jamming images and the quantification of background clutter in machine vision, an image scale based on wavelet energy and square root is proposed and applied to laser Influence of Disturbance on Imaging Tracking Performance. This scale makes use of the respective advantages of wavelet energy scale in imaging tracking system and square root scale in the target local contrast, and is suitable for the evaluation of tracking performance after laser jamming. Experimental results of laser field interference and field interference show that the scale can reflect the influence of laser interference image on the performance of CCD imaging tracking algorithm and validate the validity of the scale.
