In the pre-processing stage, in order to eliminate the ignition frequency of different scene brightness of the proposed automatic brightness adjustment methods, the LED light automatically adjust the current, making the frame images collected at different frequencies to achieve basically the same brightness. 在预处理阶段,为了消除不同点火频率对场景亮度的影响,提出了亮度自动调整方法,对LED曝光电流实现自动调整,使得采集到的帧图像在不同频率下的亮度达到基本一致。
Subject to the beef quality detection as an example, apply the brightness adjustment algorithm based on the goal of the RGB color space, and automatically adjust the brightness of the image acquisition to minimize brightness factors. 课题以牛肉品质检测为例,采用基于RGB色彩空间的目标亮度调节算法,对所采集的图像的亮度进行自动调节,以减小亮度因素的影响。
