Issue with Depth calculation of Intel Realsense camera

[RohanKurane]

Hello, I am having an issue with the depth calculation of the intel realsense camera frame. It always seems to return me a 0. Here is how I get it after receiving a frame from rs_wait_for_frames() uint16_t *depth = ( uint16_t* ) rs_get_frame_data( camera, RS_STREAM_DEPTH, &e); No error is returned from the above (e is NULL)

I then use it to calculate the rgb values as

               for( int i = 0, end = 640 * 480; i < end; ++i )
               {
                   //rgbdata[ i ].r = depth[ i ] * 60 / 999;
                   rgbdata[ i ].r /= 4;
                   rgbdata[ i ].g /= 4;
                   rgbdata[ i ].b /= 4;
               }

What am I doing wrong ? Without that the video is extremely blurry.

Im not sure if this is a depth issue or what. The video appears all dark. How can I get more color ? I increased BIRGHTNESS to max 255. Still same

I think its an issue with the RGB intensity values ? Should I use the RGB values for each frame as they are or should I process them like above divides each by 4 ? @lfelipe @anselmolsm any idea ?

Here is a pic how the video appears like on QGC. @lbegani @lucasdemarchi @lfelipe @anselmolsm Any idea what setting of the camera needs to be changed ?

Hey @RohanKurane . Unfortunately not sure exactly what might be the problem you're facing here.

This particular repository here is not being maintained anymore as the product has been discontinued. I saw you already posted on the Intel Aero Forum, but would suggest possibly asking this particular question on the Realsense forums to see if anyone there might be able to help you out (as it doesn't seem to be particularly drone specific and more related with properly obtaining/interpreting data from the realsense camera itself).

[RohanKurane]

Thanks @lfelipe I will do that. Yea,this seems odd.

[RohanKurane]

hey @lfelipe just wanted to give an update - I tried this outside and the video worked just fine. do you know what setting on the realsense camera I need to adjust for it to work in less light or the dark as well ?

[RohanKurane]

think it might be the Infrared. But I cant seem to turn it off. Tried disabling the infrared stream. Also disabling the Emitter.
