halcon相機拍照設置

HOperatorSet.SetFramegrabberParam(camera_acq_handle, "grab_timeout", -1);    超時設置  無窮

HOperatorSet.SetFramegrabberParam(camera_para_1.camera_acq_handle, "external_trigger", "true");
剛開始采集圖像，需要設置外觸發

HOperatorSet.SetFramegrabberParam(camera_para_1.camera_acq_handle, "external_trigger", "false");
軟件關閉前設置，需要關閉外觸發，相機才能正常退出來


相機初始化

 HOperatorSet.OpenFramegrabber("SaperaLT", 1, 1, 0, 0, 0, 0, "default", 8, "default", -1, "true",

                        "./SysFile/Camera1.ccf", "Xtium-CL_MX4_1", -1, -1, out camera_para_1.camera_acq_handle);
HOperatorSet.SetFramegrabberParam(camera_para_1.camera_acq_handle, "external_trigger", "true");

開始采集圖像循環

            HOperatorSet.SetFramegrabberParam(camera_para_1.camera_acq_handle, "grab_timeout", -1);

            HOperatorSet.GrabImageStart(camera_para_1.camera_acq_handle, -1); 

                HOperatorSet.GrabImageAsync(out SmallOriginalImage, camera_para_1.camera_acq_handle, -1);

軟件關閉 
HOperatorSet.SetFramegrabberParam(camera_acq_handle, "external_trigger", "false");
HOperatorSet.CloseFramegrabber(camera_para_1.camera_acq_handle);
