DepthAI Viewer data recording

Schotchaicharin

I am currently using the OAK-FFC ToF 33D with OAK-FFC 4P for ToF application.I would like to continuously record Depth/IR data and save the output as Depth/IR images.

However, I found that the DepthAI viewer only save the data as .rrd file and save just 1 frame.

Is it possible to continuousely record to Depth/IR data using DepthAI viewer?

Hi @Schotchaicharin
Recording with viewer is currently not supported. You can try our recording scripts: luxonis/depthai-experimentstree/master/gen2-record-replay

Hi,
Thank you very much for your reply.
I checked the given git hub directory, I found the Depth recording but I could not find IR recording.
Is this project support IR image recording?
If not, how can I get the IR data?

The OV9282 mono cameras have IR bandpass at 940nm, so the can see the IR light.

Hi, Jaka

Thank you for your reply.
Are you saying that there is no way to get IR data from the OAK-FFC ToF 33D module?

For evaluating my ToF application, I would like to get the depth and IR data consequetively.

If the OAK-FFC ToF 33D module IR data is available, Could you tell me how can I get the IR data?

Thanks

Hi @Schotchaicharin
What do you mean by IR data? The emitter pulsates are 80 and 100 Mhz and calculates depth based on the time taken for light to return. You get back raw values which are decoded to (640 × 480) depth image.

Hi,
By "IR data", I mean the returned signal intensity (red circle in the attached image) which usually been saved in grayscale image.
I would like to associate the acquired depth and the IR for ToF application evaluation.
Is it possible to access this data?

Hi @Schotchaicharin
The TOF node has amplitude output which should be what you are looking for.

Thanks,
