halcon相机拍照设置

HOperatorSet.SetFramegrabberParam(camera_acq_handle, "grab_timeout", -1);    超时设置  无穷

HOperatorSet.SetFramegrabberParam(camera_para_1.camera_acq_handle, "external_trigger", "true");
刚开始采集图像，需要设置外触发

HOperatorSet.SetFramegrabberParam(camera_para_1.camera_acq_handle, "external_trigger", "false");
软件关闭前设置，需要关闭外触发，相机才能正常退出来

 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");

开始采集图像循环

            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);

软件关闭 
HOperatorSet.SetFramegrabberParam(camera_acq_handle, "external_trigger", "false");
HOperatorSet.CloseFramegrabber(camera_para_1.camera_acq_handle);
