研制一种新型的基于视频图像的实时测量系统，其利用布设在甲板上的光电自准直平行光管和折转光管等相关设备，通过计算机视频判读判读系统实现实时测量艇体两维动态变形量。计算机视频判读系统接收两组光电自准直平行光管的视频信号，采用图像采集和图像处理并行工作方式，进行实时图像处理和判读，得出动态脱靶量，并对两路图像的测量结果进行叠加得出舰艇的相对变形量。Abstract: The new real-time measuring system based on video image utilizes photoelectric self-collimation parallel optic equipment 、replicate optic equipment and other equipment fixed on desk ,using computer video judge system to realize real-time measuring vessel distortion. Computer video judge system incepts two video signals, video collection and video disposing adopting parallel fashion, real-time disposes video image and judge, obtains undershoot values and relatively distortion of vessel by combining two measure results.Key words: real-time measure; video judge; undershoot value; image segmentation
