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 s2100/s210a 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. In order to keep IR enabled, you must set the IR value after turning on the device.
