摘要

在复杂的测控、发射、跟踪等系统的制造和使用中,分系统或部件间的安装位置偏差会影响控制、跟踪、发射的精度和系统其他指标测量结果的准确性,因而需要进行测量和校正。提出了基于视觉图像定位光斑中心的轴偏角测量方法,并基于LABVIEW虚拟仪器平台构建了机器视觉测角系统。以某大型武器系统为测试平台,对不同属性的轴(如发射轴、瞄准轴、激光指示器轴、制导中的测量基线等)进行归一化测量和校准,得到了满意的效果。

Abstract

In the manufacture and application of the complicated controlling, launching, tracking systems, the angular error caused by the deviation of mounting position of subsystems or assemblies in a whole system will influence the controlling, tracking and launching accuracy or other measurement results, so the error must be measured and corrected. It is very important to control the position error.A new method for measuring the boresight error between optical axes based on facular center located with vision image is presented. A machine vision angle metering system based on LABVIEW ( a virtual instrument platform ) was also constructed. It was used to align some axes (e.g.axis of launch, axis of targeting, axis of laser designator, etc.) in a large weapon system, and a satisfactory test result was got.
