基于图像的导弹姿态角的仿真实验研究

为了适应现代靶场的测量空间目标姿态角的需要，介绍了一种在实验室进行了空中目标姿态角的测量的仿真实验，从实验需要出发，开发了一种精度较高的定标方案，并给出了交会测量、目标姿态角测量的数学模型，对该姿态测量的仿真系统的测量精度进行了计算与分析，给出了实验图像预处理过程，最终实验验证了该数学模型与该测量方案是可以用来进行空间目标姿态角的测量，姿态角的测量精度首先受目标特征点的坐标测量精度的影响，其次和测量精度关系比较密切的是2个测量面的交会角，该角越接近垂直测量精度越高。

Simulation for Measuring the Missile Attitude Angle Based on Image Processing

A method of measuring the 3-D pose o f the remo te revolv ing targ et such as ro cket or missile by using the intersected measuring system w ith a proper algor ithm is described. An emulate ex periment that measuring the 3-D pose of the tar get is carr ied out in lab. A new calibrat io n method on dua-l CCD intersect ion measurement is described w hich is more accurate. This paper creates a math model o f measuring the 3- D pose of the targ et; T he measur ing pr ecision of this metho d is analyzed by using the relat ive erro r. The simulat io n result s show that this method can be used in the pract ical pr oject , The measuring precision is hig her than 0. 5b if the measuring stat io ns are arranged cor rect ly in lab.
