Greetings Jian-Hong,
I understand that you’d like to use the data shown by “capture_example.m” app. You can obtain these sensor readouts by writing a script of your own that utilizes the functions provided by the “realsense” library.
One such example is provided in the Readme file of the library: https://github.com/IntelRealSense/librealsense/blob/development/wrappers/matlab/readme.md
I suggest that you go through “capture_example.m” as it contains the logic for reading and processing sensor data apart from the code for the app UI. Your script would then look something like this:
function camera_example_without_ui()
% Make Pipeline object to manage streaming
pipe = realsense.pipeline();
% Make Colorizer object to prettify depth output
colorizer = realsense.colorizer();
% Start streaming on an arbitrary camera with default settings
profile = pipe.start();
% Set the frame rate for image caputre
period = 1.0;
% Register a function reads and processes a frame at an interval of
% "period" seconds
timer( ...
'ExecutionMode', 'fixedRate', ... % 'fixedSpacing', ...
'Period', period, ...
'BusyMode', 'queue',... % 'drop', ...
'TimerFcn',@tmProcess ...
);
pipe.stop();
end
Please add a handle to your own timer function in place of "@tmProcess" using the logic from "tmProcess" and "set_motion_data" functions in “capture_example.m”.
I hope this helps!
Thanks & regards,
Suraj.
