Dalsa-Ginie相机二次开发步骤.doc

Dalsa-Genie相机二次开发步骤Genie相机为Coreco公司的产品，因此采集使用CamExpert，开发使用SaperaLT。用户安装完SaperaLT后可查看安装路径下的帮助文件与例程进行开发（建议使用6.2或以上版本的SaperaLT，其提供更全面的例程）。函数帮助文档：DALSASaperaHelp - Sapera+Prog例程：DALSASaperaDemosClassesVC GigeCameraDemo：基本单帧采集功能，可更改buffer大小、进行显示设置GigESeqGrabDemo：连续采集与保存功能GigEFlatFieldDemo：平场校正等附加功能一 Sapera+介绍Sapera+是Sapera LT为用户提供的API. Sapera+ 包含两大类：基础应用类（Basic Classes）和GUI类（GUI Classes）。以下为Sapera应用结构图：1. 基础应用类：提供了用户进行图像开发的基本函数，命名方式为Sap类功能名，其结构如下图所示：常用类： SapAcqDevice：读写、控制相机 SapBuffer：操作bufferSapBufferWith Trash：实时处理时建立trash buffer用于存放转换数据（常用于处理速度跟不上数据采集速度时）SapTransfer：管理一般的传递过程SapView：显示buffer中存储的内容至屏幕2. GUI类：提供了许多常用设置对话框，用户可根据自己的需要选用；其结构如下图所示。常用对话框：CAbortDlg：等待对话框CAcqConfigDlg：相机配置文件导入对话框CAcqDlg：动态修改相机设置CBufDlg：Buffer设置对话框CLoadSaveDlg：导入与保存对话框二 Genie相机开发步骤：与基于Dalsa采集卡开发的CameraLink相机相比，Gig-E相机只在初始化和导入相机配置文件时有不同。1加载动态链接库：(1) 使用Basic Classes： 在Project | Settings | C/C+ | Preprocessor | Additional include directories 中加入路径C:DALSASaperaClassesBasic； 在Project|Add to Project | Files 中加入C:DALSASaperaLibSapClassBasic.lib 和 SapClassBasicD.lib； 在 Project | Settings| General中将SapClassBasic.lib 选为Exclude file from build； 在Project | Settings | C/C+ | Code Generation | Use run-time library中选择choose the option Multithreaded DLL (在release模式下) or Debug Multithreaded DLL (在debug模式下) ；在头文件中加入SapClassBasic.h。(2) 使用GUI： 在Project | Settings | C/C+ | Preprocessor | Additional include directories 中加入路径C:DALSASaperaClassesGui； 在Project|Add to Project | Files 中加入C:DALSASaperaLibSapClassGui.lib 和 SapClassGuiD.lib； 在 Project | Settings| General中将SapClassBasic.lib 选为Exclude file from build for Win32 Release； 在In Project | Settings | C/C+ | Code Generation | Use run-time library中选择choose the option Multithreaded DLL (在release模式下) or Debug Multithreaded DLL (在debug模式下) ；在头文件中加入SapClassGui.h。2 初始化资源：m_AcqDevice= new SapAcqDevice(dlg.GetLocation(), dlg.GetConfigFile();m_Buffers= new SapBufferWithTrash(2, m_AcqDevice);m_Xfer= new SapAcqDeviceToBuf(m_AcqDevice, m_Buffers, XferCallback, this);m_View = new SapView(m_Buffers, m_viewWnd.GetSafeHwnd();使用SapAcqDevice类：The SapAcqDevice Class provides the functionality for reading/writing features from/to devices such as a GigE-Vision camera. The class also contains functions for sending commands and registering events to devices.3连接相机：首先在CamExpert中配置好相机参数并保存为.ccf文件，当相机初始化完成后，导入此文件。用户可使用GUI-CAcqConfigDlg对话框方便操作。使用SapLocation类：The SapLocation Class identifies a Sapera server/resource pair。4完成采集与处理功能后释放资源。三更改相机参数获得相机信息：SapAcqDevice:GetFeatureInfo设置相机信息：SapAcqDevice:SetFeatureValue常用相机参数信息：1相机与芯片信息：Interface = GigE Vision = 0DeviceVendorName = DALSADeviceModelName = Genie M640 for Genie M640DeviceScanType = Areascan = 0ColorType = Monochrome Sensor = 0SensorWidth = Width of the sensor in pixelsSensorHeight = Height of the sensor in linesPixelSize = Number of bits per pixel2Binning: BinningHorizontal = Disabled = 1, 2 pixels = 2BinningVertical = Disabled = 1, 2 lines = 23曝光控制：FrameRate = 0.1 Hz up to max.
