摘　　要：考虑高能电子束冲击实验中韧致辐射靶丝对精确复位的需求,设计了用于靶丝精确复位的辅助系统。首先,根据双目视觉原理推导了用于复位系统的重要公式;然后,根据实际使用的工况,设计了靶丝精确复位系统方案,包括硬件指标论证和软件算法设计。最后,在模拟真实工况环境下,搭建了实验平台,对系统的复位精度误差进行了测算。测试结果显示所研制的复位系统的复位精度误差为2%。半实物仿真实验结果显示,这套复位系统实现了高能电子束冲击实验中对韧致辐射靶丝的精确复位。由于研究对象是复位系统,而非定位系统,不需要进行标定,因此不存在标定误差,其研制成功保证了高能电子束冲击实验的可靠性。In consideration of the demand of bremsstrahlung conversion target filament for accurate re- storing in high-energetic particle burst experiments,a service device for target filament accurate resto- ring was designed. First, some key formulas of restoring system were derived according to the stereo-scopic theory. Then, a scheme for design of an accurate restoring system of the micro target filament was proposed according to the real application. Finally, an experiment platform to simulate real condi- tions was established to test the restoring accuracy error of this system. The experiment results indi-cate that the accuracy error of this restoring system is 2 %. The semi-physical simulation experiment il- lustrates that this restoring system reaches the accurate restoring of the bremsstrahlung conversion target filament in the high-energetic particle burst experiments. As the research object is a restoringsystem rather than a positioning system, it do not need to be calibrated, so there is no calibration er- ror. The target filament accurate restoring system developed ensures the reliability of high energy e-lectron beam burst experiments.
