OpenNI2 extension introduction

n order to support the framework in OpenNI2 to implement the call to the Smart module, the corresponding driver library samrttof.dll is provided in the SDK, This driver follows the definition of OpenNI2 in OniDriverAPI.h, which mainly includes DriverService, DriverBase, DeviceBase, StreamBase In these several categories, the driver source code for smarttof.dll is released in the SDK.

SmartToF module settings

All related parameter settings and use of filtering functions in SmartToF are performed through the setProperty function in the smarttofStream class, according to setProperty set the corresponding propertyId.

The following table lists the property ID of the property:

function ID	Description
PROPERTY_ID_PARAM_SET	Module parameter setting IDID
PROPERTY_ID_PARAM_GET	Module parameter acquisition ID
PROPERTY_ID_FILTER_LEN_CALIB_ENABLE	Lens filter enable
PROPERTY_ID_FILTER_LEN_CALIB_DISABLE	Lens filter disable
PROPERTY_ID_FILTER_PIXEL_CALIB_ENABLE	Pixel filtering enabled
PROPERTY_ID_FILTER_PIXEL_CALIB_DISABLE	Pixel filtering disabled
PROPERTY_ID_FILTER_AMP_CALIB_ENABLE	Amplitude filtering enabled
PROPERTY_ID_FILTER_AMP_CALIB_DISABLE	Amplitude filtering disabled
PROPERTY_ID_FILTER_AUTO_INTG_ENABLE	Auto exposure enabled
PROPERTY_ID_FILTER_AUTO_INTG_DISABLE	Auto exposure disabled
PROPERTY_ID_FILTER_TEMP_MONITOR_ENABLE	Temperature monitoring enabled
PROPERTY_ID_FILTER_TEMP_MONITOR_DISABLE	Temperature monitoring disabled
PROPERTY_ID_FILTER_HDR_ENABLE	HDR function enable
PROPERTY_ID_FILTER_HDR_DISABLE	HDR function disable

Sample code for module setup under OpenNI2

In OpenNI2, you can set the property ID in the above list to the SmartToF module through setProperty. For specific setting code examples, please refer to the setting of integration time code below.:

dmcam_param_item_t wparam;  //setting integration time
wparam.param_id = PARAM_INTG_TIME;
wparam.param_val.intg.intg_us = intg;
wparam.param_val_len = sizeof(wparam.param_val.intg.intg_us);
depth.setProperty(PROPERTY_ID_PARAM_SET, (void *)&wparam, sizeof(wparam));

The code to get the module settings is as follows:

dmcam_param_item_t rparam;  //getting framerate
rparam.param_id = PARAM_FRAME_RATE;
rparam.param_val_len = sizeof(rparam.param_val.frame_rate.fps);
depth.getProperty(PROPERTY_ID_PARAM_GET, &rparam);
printf("frame rate:%d fps\n", rparam.param_val.frame_rate.fps);
