摘要
设计了一种利用单脉冲正向峰值探测电路构成的CCD二值化阈值自动调节方法。分析了峰值探测电路产生漂移现象的原因,提出了解决方法。实验结果表明,该方法可达到100倍左右的自动调节范围,实现了野外自然光照明条件下的CCD输出信号二值化阈值的自动调节。
A kind of automatic adjustment method of CCD binary threshold was designed, which is based on the peak detection circuit of positive single pulse. The cause of peak detector drift was analyzed and solved. The result of the experiment shows that the automatic adjustment range is about 100 times , which realizes automatic adjustment of CCD binary threshold in the natural light.
