To determine the temperature of the camera's core board or sensor board, get the value of the DeviceTemperature parameter.
The temperature is given as a floating-point value in degrees Celsius.
The camera also provides a TemperatureSelector parameter. This allows you to choose the location within the device where the temperature is measured.
On Basler cameras, the parameter is preset and can't be changed.
// Get the current device temperature
double d = camera.DeviceTemperature.GetValue();
INodeMap& nodemap = camera.GetNodeMap();
// Get the current device temperature
double d = CFloatPtr(nodemap.GetNode("DeviceTemperature"))->GetValue();
// Get the current device temperature
double d = camera.Parameters[PLCamera.DeviceTemperature].GetValue();
// Get the current device temperature
double d = Pylon.DeviceGetFloatFeature(hdev, "DeviceTemperature");
/* Macro to check for errors */
#define CHECK(errc) if (GENAPI_E_OK != errc) printErrorAndExit(errc)
GENAPIC_RESULT errRes = GENAPI_E_OK; /* Return value of pylon methods */
double d = 0;
/* Get the current device temperature */
errRes = PylonDeviceGetFloatFeature(hdev, "DeviceTemperature", &d);
CHECK(errRes);
You can also use the pylon Viewer to easily set the parameters.
