Abstract

摘要: 棉花杂质的有效检测和剔除对于棉花质量的控制具有重要意义. 本文提出了一种实用的棉花杂质高速检测方法. 该方法利用 3D-LUT 技术, 有效解决了颜色空间转换的时间耗损问题. 利用 HSI 颜色空间的色度和饱和度信息, 对棉花中的杂质进行高效检测和定位. 彩色运动补偿技术的应用, 弥补了相机在硬件上进行空间参数校正的不足, 降低了杂质的错误判别率. 实验结果表明, 该系统可以在 10ms 内完成 80 线棉流图像的采集、图像格式转换、杂质的检测和定位等全部过程. 在棉流速度为 18m/s, 杂质大小为 2×2mm2 的情况下, 杂质识别正确率可达到 95.4%. 关键词: HSI颜色空间 / 棉花杂质 / 查找表 / 运动补偿
