在網(wǎng)上搜索半天,沒(méi)有找到關(guān)于Sentech相機(jī)和halcon聯(lián)合編程的例子,先將自己的代碼發(fā)布如下.

sentech相機(jī)驅(qū)動(dòng)和sdk 下載地址 

參考PvPipelineSample這個(gè)例子,自己修改后就可以連接相機(jī).

SDK獲得圖像類(lèi)型是其自定義的 PvBuffer

                           PvImage  pvImage =  lBuffer.Image;
                           Int32 width = (Int32)pvImage.Width;
                           Int32 height = (Int32)pvImage.Height;
                           Bitmap bitMap = new Bitmap(width, height);
                           pvImage.CopyToBitmap(bitMap);
                           HObject hObject = HImageConvertFromBitmap32(bitMap);

</pre><p></p><p></p><pre code_snippet_id="1638895" snippet_file_name="blog_20160408_3_2876536" name="code" class="csharp">        private static HObject HImageConvertFromBitmap32(Bitmap bmp)
        {
            HObject ho_Image;
            HOperatorSet.GenEmptyObj(out ho_Image);
            unsafe
            {
                System.Drawing.Imaging.BitmapData bmpData = bmp.LockBits(new System.Drawing.Rectangle(0, 0, bmp.Width, bmp.Height), ImageLockMode.ReadOnly, System.Drawing.Imaging.PixelFormat.Format32bppRgb);
                unsafe
                {
                    HOperatorSet.GenImageInterleaved(out ho_Image, bmpData.Scan0, "bgrx", bmp.Width, bmp.Height, -1, "byte", bmp.Width, bmp.Height, 0, 0, -1, 0);
                }
                return ho_Image;
            }
        }

第二種方法是使用指針,

在網(wǎng)上看到一段代碼,是如何獲取byte[]的指針

                           //byte[] outputData = new byte[2];
                           //void* p;
                           //IntPtr ptr;
                           //fixed (byte* pc = outputData)
                           //{
                           //    p = (void*)pc;
                           //    ptr = new IntPtr(p);
                           //}

byte* pter = pvImage.DataPointer;

于是聯(lián)想到halcon的gen_image1最后一個(gè)參數(shù)也是需要指針

void HImage.GenImage1(string type, int width, int height, IntPtr pixelPointer)

于是便有了下面的代碼

                           HImage hObject1 = new HImage();
                           byte* pter = pvImage.DataPointer;
                           hObject1.GenImage1("byte", width, height, new IntPtr(pter));

使用bitmap方法我的電腦耗時(shí)約為100ms,使用后面這種指針?lè)椒ê臅r(shí)約為5ms
