摘要
目前研究的航天器目标跟踪控制系统控制有效率低,追踪图像与实际目标不同,准确率低;基于图像轮廓检测设计了一种新的航天器目标跟踪控制系统,根据系统硬件的不同性能与结构进行模块式划分,同时将图像轮廓检测数据准则添加入中心管理系统中,时刻保证数据的检测安全系数处于系统操作允许范围内;调整原有的软件结构状态,采集航天器轮廓图像并提取轮廓信息,选用适当的图像轮廓检测阈值,集中检验跟踪目标的运动方向,调控方向数据,以此降低图像的像素变化程度,得到准确的航天器目标跟踪控制结果;实验结果表明基于图像轮廓检测的航天器目标跟踪控制系统控制有效率达到了84%,跟踪目标更加准确。
The currently studied spacecraft target tracking control system has low control efficiency,the tracking image is different from the actual target,and the accuracy is low.A new spacecraft target tracking control system is designed based on image contour detection,which is divided into modules according to the different performance and structure of the system hardware,and the image contour detection data criterion is added to the central management system to ensure the safety of data detection at all times.The coefficient is within the allowable range of system operation;adjust the original software structure state,collect the contour image of the spacecraft and extract the contour information,select the appropriate image contour detection threshold,centrally check the movement direction of the tracking target,and adjust the direction data to reduce the image The degree of change of the pixels can get accurate spacecraft target tracking control results.The experimental results show that the control efficiency of the spacecraft target tracking control system based on image contour detection is 84%,and the target tracking is more accurate.
