Enable IR and its adjustments function
|
||
=======================================
|
||
|
||
Using the ``SetOptionValue()`` function of the API, you can set various control values for the current open device.
|
||
|
||
Enabling IR is setting ``Option::IR_CONTROL`` greater than 0. The greater the value, the greater the IR's intensity.
|
||
|
||
.. Attention::
|
||
* mynteye s21XX doesn't support this feature.
|
||
|
||
Reference Code:
|
||
|
||
.. code-block:: c++
|
||
|
||
auto &&api = API::Create(argc, argv);
|
||
|
||
// Detect infrared add-ons
|
||
LOG(INFO) << "Support infrared: " << std::boolalpha
|
||
<< api->Supports(AddOns::INFRARED);
|
||
LOG(INFO) << "Support infrared2: " << std::boolalpha
|
||
<< api->Supports(AddOns::INFRARED2);
|
||
|
||
// Get infrared intensity range
|
||
auto &&info = api->GetOptionInfo(Option::IR_CONTROL);
|
||
LOG(INFO) << Option::IR_CONTROL << ": {" << info << "}";
|
||
|
||
// Set infrared intensity value
|
||
api->SetOptionValue(Option::IR_CONTROL, 80);
|
||
|
||

At this point, if the image is displayed, you can see IR speckle on the image, as below:
|
||
|
||
.. image:: ../../../images/sdk/ir.png
|
||
|
||
|
||
.. attention::
|
||
|
||
The hardware will not record the IR value after being turned off and will reset to 0. In order to keep IR enabled, you must set the IR value after turning on the device.
