摘要
目前,图像测量作为一种非接触式的位姿测量技术,已经在航空航天领域的空间探测与测量任务中得到了广泛应用。该技术通过视觉成像装置对空间目标进行拍摄,并根据目标的三维空间特征和其经相机成像后在图像中的二维投影求解位姿参数。首先,介绍了箭载图像测量装置的发展现状,并总结了其面临的主要问题及应对策略;然后,从箭体分离和火箭喷管姿态测量两个具体应用出发,梳理了航天领域中箭载图像测量的关键技术原理及其发展过程;最后,基于研究现状总结和关键技术分析,探讨了箭载图像测量技术目前存在的主要难题,并给出后续发展的建议。
Image measurement,as a noncontact pose-measurement technology,has been widely applied in various space exploration and measurement tasks in the aerospace industry.It captures spatial targets through visual imaging devices,combines the three-dimensional(3D)spatial features of the targets and their two-dimensional projections in the image,and calculates the pose parameters of the targets.This paper introduces the current development status of a rocket-borne image-measurement device and summarizes the problems it encounters and the corresponding solutions.Based on two specific applications,namely the separation of the rocket body and the measurement of the rocket-nozzle attitude,the principles and development of key technologies for rocket-borne image measurement in the aerospace field are summarized.Finally,based on the current research status and key technology analysis,the main challenges of rocketborne image-measurement technology are discussed and recommendations for future development are provided.
