Test Patterns (dart E)

相机的 Test Patterns 功能可让您检查相机的基本功能及其传输图像的能力。

Test patterns 可用于维护目的和故障诊断。它们是由相机本身生成的，即相机的光学元件和成像传感器未参与其创建。

该功能的使用

显示测试图案

显示测试图案，请执行以下操作:

1. 通过将 TestPattern 参数设置为所需的测试图像来选择测试图案。
2. 至少采集一张图像以显示所选的测试图案。如果要在 pylon Viewer 中显示测试图案，请单击工具栏中的“单拍”或“连拍”按钮。

示例代码

C++ (Native)C++ (Generic)C#C (Generic)PythonC

// Select test image 1
camera.TestPattern.SetValue(TestImageSelector_Testimage1);
// Acquire images to display the selected test image
// ...
// (Insert your own image grabbing routine here.
// For example, the InstantCamera class provides the StartGrabbing method.)

INodeMap& nodemap = camera.GetNodeMap();
// Select test image 1
CEnumParameter(nodemap, "TestPattern").SetValue("Testimage1");
// Acquire images to display the selected test image
// ...
// (Insert your own image grabbing routine here.
// For example, the InstantCamera class provides the StartGrabbing method.)

// Select test image 1
camera.Parameters[PLCamera.TestPattern].SetValue(PLCamera.TestImageSelector.Testimage1);
// Acquire images to display the selected test image
// ...
// (Insert your own image grabbing routine here.
// For example, the InstantCamera class provides the StartGrabbing method.)

#define CHECK(errc) if (GENAPI_E_OK != errc) printErrorAndExit(errc)
GENAPIC_RESULT errRes = GENAPI_E_OK;  /* Return value of pylon methods */
/* Select test image 1 */

CHECK(errRes);

camera.TestPattern.Value = "Testimage1"
# Acquire images to display the selected test image
# ...
# (Insert your own image grabbing routine here.
# For example, the InstantCamera class provides the StartGrabbing method.)
