| void rs_enable_motion_tracking_cpp | ( | rs_device * | device, |
| rs_motion_callback * | motion_callback, | ||
| rs_timestamp_callback * | timestamp_callback, | ||
| rs_error ** | error | ||
| ) |
Enables and configures motion-tracking data handlers.
Note:
The rs_enable_motion_tracking_cpp() method is responsible for activating the motion module on-board the device. One of the services it provides is to produce shared and high-resolution timestamps for all components that are connected to it. For Depth, IR, Color and Fisheye sensors, librealsense takes care of that and copies the timestamps on the relevant frames.
However, when you have an external device (such as a compass, magnetometer, light sensor, or other) and wish to synchronize it precisely with image and motion streams, you can connect that sensor to a GPIO that is available on some devices. Every time the sensor signals, you get a timestamp callback with a frame number, source ID, and a timestamp. This timestamp callback allows advanced users to synchronize compass events (presumably coming though I2C or some other method) with RealSense data.
This variant of rs_enable_motion_tracking() is provided specifically to enable passing lambdas with capture lists safely into the library.
- Parameters
-
[in] device Relevant RealSense device [in] motion_callback User-defined routine to be invoked when motion data arrives [in] timestamp_callback User-defined routine to be invoked on timestamp [out] error If non-null, receives any error that occurs during this call, otherwise, errors are ignored.
