Basler Pylon 簡單抓圖

簡單抓圖步驟：

• StartGrabbing 開始抓取，狀態 isGrabbing
• RetrieveResult 接收數據，完成后觸發 StopGrabbing
• 數據由 CGrabResultPtr 指針接收，狀態 GrabSucceeded
• runtime 由 PylonInitialize 初始化，並由 PylonTerminate 銷毀

具體代碼如下：

 Step0：初始化 Pylonruntime

    // Before using any pylon methods, the pylon runtime must be initialized.
    PylonInitialize();
    //Pylon::PylonAutoInitTerm autoInitTerm;

 

Step1: 創建 Camera 實例

        // Create an instant camera object with the camera device found first.
        IPylonDevice *pDevice = CTlFactory::GetInstance().CreateFirstDevice();
        CInstantCamera camera;
        camera.Attach(pDevice);

 

Name of Class	Usable for Device Type	Device-specific
Pylon::CInstantCamera (recommended)	All cameras	No
Pylon::CBaslerUniversalInstantCamera (recommended for novice users)	All cameras	No
Pylon::CBasler1394InstantCamera	IIDC 1394 compliant cameras	Yes
Pylon::CBaslerGigEInstantCamera	GigE Vision compliant cameras	Yes
Pylon::CBaslerUsbInstantCamera	USB3 Vision compliant cameras	Yes
Pylon::CBaslerCameraLinkInstantCamera	Camera Link compliant cameras	Yes

 

step2：開始抓取

        // Start the grabbing of 1 images.
        // The camera device is parameterized with a default configuration which
        // sets up free-running continuous acquisition.
        camera.StartGrabbing(1);

 

step3：構造智能指針接收抓取數據

        // This smart pointer will receive the grab result data.
        CGrabResultPtr ptrGrabResult;

 

step4：判斷抓取狀態，並接收數據

        // Camera.StopGrabbing() is called automatically by the RetrieveResult() method
        // when c_countOfImagesToGrab images have been retrieved.
        int flag = 0;
        while ( camera.IsGrabbing())
        {
            // Wait for an image and then retrieve it. A timeout of 5000 ms is used.
            camera.RetrieveResult( 5000, ptrGrabResult, TimeoutHandling_ThrowException);

 

step5：判斷抓取結果，並處理

            // Image grabbed successfully?
            if (ptrGrabResult->GrabSucceeded())
            {
                // Access the image data.
                cout << "SizeX: " << ptrGrabResult->GetWidth() << endl;
                cout << "SizeY: " << ptrGrabResult->GetHeight() << endl;
                const uint8_t *pImageBuffer = (uint8_t *) ptrGrabResult->GetBuffer();

 

step6：釋放 plyon runtime

    // Releases all pylon resources.
    PylonTerminate();

 

調試時，相機意外中斷，連不上的處理

The device is controlled by another application. Err: An attempt was made to access an address location which is currently/momentary not accessible. (0xE1018006)

設置環境變量 PYLON_GIGE_HEARTBEAT =1000 即可。
