1：假如单独调用FindShapeModel()方法执行所需要时间为100mms ;那我用多线程调用FindShapeModel()\FindShapeModel1()所用的时间应该也是100ms 左右，但实际测试发现会大于100*2ms ,偶尔有100ms左右的情况出现。
2：求解原因，代码中有设置让线程运行在不同的CPU上，但根据实没时间，好像还是运行在同一个CPU上。
3：FindShapeModel()\FindShapeModel1()方法内容一样的，只是名称不一样。
4：硬件配置 intel core(TM)-i7-7700 CPU
private void FindShapeModel()
{
Thread.BeginThreadAffinity();
IntPtr handle = GetCurrentThread();
int id = Thread.CurrentThread.ManagedThreadId;
uint id1 = GetCurrentThreadId();
UIntPtr rtn = SetThreadAffinityMask(handle, new UIntPtr(0x000F));
uint rtn1 = GetLastError();
QueryPerformanceCounter(ref time[15]);
isFinish[0]= FindShapeModel(hv_ModelID,ho_Image);
Thread.EndThreadAffinity();
}
private void FindShapeModel1()
{
Thread.BeginThreadAffinity();
IntPtr handle = GetCurrentThread();
int id = Thread.CurrentThread.ManagedThreadId;
uint id1 = GetCurrentThreadId();
UIntPtr rtn = SetThreadAffinityMask(handle, new UIntPtr(0x0001));
uint rtn1 = GetLastError();
FindShapeModel1(hv_ModelID, ho_Image1);
Thread.EndThreadAffinity();
}
MyThread[0] = new Thread(new ThreadStart(FindShapeModel));
MyThread[0].Start();
MyThread[1] = new Thread(new ThreadStart(FindShapeModel1));
MyThread[1].Start();
