基于目标检测算法的HEPS-BPIX4 DAQ实时在线图像压缩研究

open access: yesHe jishu
面向高能同步辐射光源(High Energy Photon Source,HEPS)的高性能像素阵列探测器(HEPS-BPIX4)的数据获取系统(Data Acquisition,DAQ)需满足高实时性要求。通过在线压缩图像数据,可有效降低后续传输与存储的压力。针对传统压缩算法在压缩率和实时性方面的不足,本文提出了一种基于深度学习目标检测的图像数据在线压缩方法。采用端到端的YOLO(You Only Look Once)目标检测算法,对深度学习模型进行高效训练,并验证了其在HEPS-BPIX4 ...

抽油杆直线度摄像测量方法与系统

open access: yesShiyou jixie, 2015
直线度是机械加工中重要的测量参数,抽油杆直线度直接关系到其产品质量,但一直没有较好的测量手段。为此,提出一种基于阵列摄像的机器视觉测量方法。测量系统通过采集抽油杆的边缘轮廓图像,进行形态学的图像处理,得到一段抽油杆表面轮廓直线,通过激光线条提供直线基准,与20台相机测量的轮廓线比对,获得10 m抽油杆的全长直线度。测量系统通过旋转抽油杆,获得多个圆周方向上的直线度,其测量精度为0.5 mm/m,测量速度为2根/min,可实现非接触、高精度的快速直线度测量。
