| 摘 要： | 破片参数测量系统中,摄像机的定位造成了上位机CPU的空闲,降低了测量系统的实时性和测量效率.采用多线程技术能有效解决此问题.文中详细介绍了C++Builder中多线程技术的要点以及该技术在本系统中的实现方法.本系统共创建两条线程,第一线程(主线程)负责上位机与下位机之间的通信,第二线程负责图像处理.系统运行结果表明不采用多线程技术时单个破片测量时间为57s,而采用多线程技术时单个破片的测量时间为31s.由此可见,多线程技术能显著提高系统的实时性和测量效率.

| Abstract: | In fragment parameter measurement system,the upper machine's CPU leisure is caused by camera positioning,and the real-time and measurement efficiency of the measurement system are reduced greatly.The multithread technology can effectively solve this problem.The principle and implementation of multithread technique in C++ Builder were introduced.To meet the requirement of real-time,this system created two threads totally.The first thread(main thread) was responsible for communication between the upper machin... |
