摘要

为降低计算复杂度和系统响应时间

提出了图像采集卡硬件参数自动优化的工程实现算法。通过统计图像直方图两端的数据量获得信息熵的九种状态

并依据所处状态的不同对采集卡硬件参数进行动态调整

从而改变图像的亮度和对比度获得图像最大熵。实验结果表明在单帧时间延迟的条件下

此种方法可以完成对图像采集卡硬件参数的自适应优化。

Abstract

In order to simplify computation and reduce system response time

an algorithm has been proposed for automatic optimization of image board parameters. Maximum entropy is obtained by establishing nine different states of image entropy from statistics at both ends of image histograms

dynamically adjusting the image board parameters in accordance with the states of image entropy

and then changing the brightness and contrast of images. Experimental results indicate that under the condition of single-frame time delay

this algorithm can be applied for adaptive optimization of image board parameters.
