MIL即为Matrox Imaging Library 的缩写，是加拿大Matrox公司提供的图像处理函数库，主要是针对其公司生产的Matrox系列图像采集卡。我使用的是一个Matrox Morphis四通路图像采集卡，需要使用MIL开发自己的视觉系统。
几个常用的函数如下：
MappAllocDefault（）；一个默认的配置，Application、System、Digitizer、Display、Buffer都是按照默认的情况进行配置。
MappAlloc（）；分配一个MIL应用，该函数要在使用其它MIL函数之前使用。
MsysAlloc（）；配置一个硬件环境，指定使用得板卡类型，使用板卡序号。该函数要在分配buffer，display，digitizer前使用。
MdigAlloc（）；配置一个抽象的图像采集卡，指定可以使用的采集卡通道数，然后才能使用图像采集卡的函数。
MdispAlloc（）；配置一个display，把摄像机采集的图像使用该抽象进行显示。
MbufAlloc2d（）；分配一个2维的内存区。
MbufAllocColor（）；分配彩色内存区。
MappControl（）；改变指定的MIL应用的属性。
MsysControl（）；改变指定的系统的属性。
MdigControl（）；改变指定的图采卡属性。
MdispControl（）；改变指定的显示属性
MappInquire（）；获取指定的应用配置情况
MsysInquire（）；获取指定的应用系统情况
MdigInquire（）；获取指定的采集卡配置情况
MdispInquire（）；获取指定的显示配置情况
MbufInquire（）；获取指定内存块的配置情况
我使用的Matrox Morphis有四个通路，现在有两个摄像机需要采集数据。黑白摄像机在插在0通路，为CCIR机制；彩色摄像机插在1通路，为PAL机制。
目前最广泛的标准视频是
黑白：RS—170，使用在北美、日本、台湾等地区； CCIR，使用在欧洲、中国等地区。
彩色：NTSC，使用在北美、日本、台湾等地区； PAL，使用在欧洲、中国等地区。
下面分别采集两个摄像机视频数据程序的核心地方

}
MbufFree(ColorMilImageDisp); MbufFree(ColorMilImage); MdispFree(ColorMilDisplay); MdigFree(ColorMilDigitizer); MsysFree(ColorMilSystem); MappFree(ColorMilApplication);
今天学习了如何对图像采集卡采集的每一帧图像进行图像处理，主要是从MIL的数据结构中读出图像的具体到像素的数据。SizeX为图像的长度，SizeY为图像的宽度，SizeBand为图像的颜色通道数。从读出的数据分析可以知道，具体图像像素数据是从上到下，从作到右存储的。
unsigned char *data=new unsigned char[SizeX*SizeBand*SizeY]; unsigned char red=0,green=0,blue=0; int k=10;//连续采集的10帧图像 int i,j; while(k--) { MdigGrab(ColorMilDigitizer, ColorMilImage8[0]);
MbufGetColor(ColorMilImage8[0],M_PACKED +M_BGR24,M_ALL_BANDS,data); for(i=0;i<SizeY/2;i++) for(j=0;j<SizeX*SizeBand;j+=SizeBand) { blue=*(data+i*SizeX*SizeBand+j+0); green=*(data+i*SizeX*SizeBand+j+1); red=*(data+i*SizeX*SizeBand+j+2); } MbufPutColor(ColorMilImage8[0],M_PACKED +M_BGR24,M_ALL_BANDS,data);
MbufCopyColor(ColorMilImage8[0],ColorMilImageDisp,M_ALL_BANDS );
} delete data;
设定两个线程分别采集两个摄像机的信号，同时主线程控制两个线程的运行。这个双摄像机同步弄了好久，终于调出来了，好高兴啊
