深海集矿机视频测速中目标定位算法研究

Research of Target Orientable Algorithm for Speed Measurement of Deep-sea Mining by Video Image

实现深海集矿机视频测速的关键难点是在间隔已知时间的两幅视频帧图像中找到可以作为测速目标的对应块。根据集矿机行走作业的深海底环境,以锰结核区域为对应块,采用灰度差水平叠加投影的方法,构造可以代表其鼓形区域的函数,以其作为定位结核区域的判别函数。此算法能够快速、准确地定位到结核区域,从而为深海集矿机视频测速的关键难点提出了一种切实可行的解决办法。

According to the speed equation of speed measurement of Deep-sea Mining by video image,the key point to get the speed,is to look for a way to get the position of same block in the two images,if we have two images which the acquisition time between them has been known, A fast manganese block locating method based on Deep- sea bed haracteristic and horizontal gray level difference projection was provided to solve the main difficulty of the algorithm,The rapid and accurate algorithm indicate the possibility to offer areal-time system and to measure speed of Deep-sea Mining by video.
