摘　　要：简要介绍了直升机传动系统同轴度测量设备。根据测量结果的实时显示要求,系统程序中采用了多线程技术。第一线程(主线程)负责与外设通信、结果处理及与用户交互;第二线程负责图像处理。实践表明两线程并行工作时视频图像及测量结果的显示满足系统的实时性要求。A method of measuring the coaxial degree for the helicopter transmission with laser beam is presented briefly. To meet the requirement of real-time, the main program adopts muhithread technology. The first thread takes charge of the communication with other device and the management of results. The images were processed in the second thread. In practice, the display of video and measurement meet the requirement of real-time when the two thread worked in parallel.
