【摘要】 为了提高高功率激光装置中各组成系统调试阶段的工作效率,利用OpenGL图形软件建立靶了定位仿真系统,使得靶定位算法的调试和初步验证在实验平台等硬件条件尚未完善的情况下能够独立进行。利用模板匹配和3-CCD空间定位法对靶丸进行定位监测,并考虑姿态调整过程中由于靶杆长度引起的位置偏移,在算法中给予补偿。仿真系统不仅实现了目标靶丸、送靶机构等虚拟构建,还运用OpenGL成像技术实现了CCD仿真图像的采集。最后利用该仿真系统对靶丸特征检测、空间位姿计算、补偿式姿态调整等算法进行了调试。结果表明,通过相机监测可将靶丸由任意位姿调至目标零位,验证了该检测与定位算法应用于实际工程的可行性。更多还原

【Abstract】 To improve the operating efficiency of high power laser facility project, a simulation system using"OpenGL"graphics software is built to evaluate the target positioning algorithm at the debugging phases, which is independent on unperfect hardware experimental environment. The proposed positioning method calculates the target′s spatial coordinate and rotational angles by integrating the feature values abtained by three CCDs,and adjusts the target-sending mechanism to put the target in a desired position. The simulation results show the target-sending mechanism is confirmed to be able to adjust the target in a desired position based on the measurement results, which verifies the practicality of the proposed positioning algorithm to be used in the real ICF physical experiment.更多还原
