Hello

We want to calibrate the camera using nvmedia.

we found next sample.

home/NVIDIA/Drive/5050bL_SDK/DriveSDK/drive-t186ref-linux/samples/nvmedia/img_cc/drive-px2-a/dvp_o_ar0231_raw12_hdr_1920x1236_ab_ta_rccb_v7

What do the following parameters mean in the file?

How do I modify parameters to proceed with camera calibration?

EX) in the file
#line 68

Exposure control

20 3362 00 00 # C_GAIN 1.0 → How to modify parameters to GAIN 1.2??

Thanks

hello jinsankim12,

please refer to below,

Exposure control

20 3362 00 00 # C_GAIN 1.0
3362 <== this is the register address for DC_GAIN,
00 00 <== the input values settings

you should also contact the sensor vendor, and please check AR0231 register map for details,
you may also found the documentation under …/nvmedia/docs/nvmimg_cc_user_guide.md, please also refer to the notes and requirement for ar0231 calibration.
thanks

Thanks

We have analyzed the example and this is an example for initial setting of camera parameters.

I want to change the camera parameter values ​​in real time.

The features I want are in the following document links.

https://docs.nvidia.com/drive/nvvib_docs/index.html#page/NVIDIA%2520DRIVE%2520Linux%2520SDK%2520Development%2520Guide%2Fipp_framework.html%23

Where can I find the NvMedia IPP framework sample code?

thanks
