libargus not working as expected

kjasper · February 29, 2020, 1:23am

Hello, I am running a modified version of example 13 to control two csi-2 cameras without ISP autocontrols.

This is my main loop:

while (true) {
                for (uint32_t j = 0; j < 2; j++)
                {
                    ICaptureSession *iCaptureSession = interface_cast<ICaptureSession>(captureHolders[j].get()->getSession());
                    Request *request = captureHolders[j].get()->getRequest();
                    IRequest *iRequest = interface_cast<IRequest>(request);
                    IAutoControlSettings *iAutoControlSettings = interface_cast<IAutoControlSettings>(iRequest->getAutoControlSettings());
                    if (!iAutoControlSettings)
                        ORIGINATE_ERROR("Failed to get AutoControlSettings interface");
                    iAutoControlSettings->setIspDigitalGainRange(Range<float>(1.0));
                    iAutoControlSettings->setAwbMode(AWB_MODE_OFF);
                    iAutoControlSettings->setColorCorrectionMatrixEnable(true);
                    ISourceSettings *iSourceSettings = interface_cast<ISourceSettings>(iRequest->getSourceSettings());
                    if (!iSourceSettings)
                        ORIGINATE_ERROR("Failed to get SourceSettings interface");
                    iSourceSettings->setFrameDurationRange(Range<uint64_t>(1e9/FPS));
                    iSourceSettings->setGainRange(Range<float>(100.0));
                    iSourceSettings->setOpticalBlackEnable(true);
                    iSourceSettings->setOpticalBlack(0.04);
                    iSourceSettings->setExposureTimeRange(Range<uint64_t>(140000000));
                    if (j == 1) {
                        iAutoControlSettings->setColorCorrectionMatrix(g_matrix);
                    }
                    uint32_t frameId = iCaptureSession->capture(request);
                    if (frameId == 0)
                        ORIGINATE_ERROR("Failed to submit capture request");
                }
            }

Even though I am setting the gain, exposure, etc., the exposure is fluctuating and the setGainRange is ignored. Here is the log output:

hello lancehxh2z,

it’s not correct that you have implementation without ISP autocontrol.
please refer to Camera Software Development Solution chapter, and you may refer to [Camera Architecture Stack] session for software architecture.
could you please verify gain control works well with argus_camera application?

kjasper · February 29, 2020, 1:58am

1) it's not correct that you have implementation without ISP autocontrol.

What do you mean by this? I simply want the ISP to debayer my image to NV12/YUV/RGB. You’re saying libargus can’t do this? I would expect a low level imaging library not to force me to color correct my image.

hello lancehxh2z

I would like to revise your understanding,

Hello, I am running a modified version of example 13 to control two csi-2 cameras without ISP autocontrols.
you’re running example 13 which actually with ISP autocontrols.
thanks

kjasper · February 1, 2020, 7:16am

OK, well please provide settings to prevent the ISP autocontrols from color correcting the image. Every time I turn on the sensor through libargus the image looks different even with AWB off.

Also, why does the system lock for 60 seconds before I can turn on jetson_clocks.sh? I’d like to use the system without waiting a minute.

JerryChang · May 6, 2020, 5:42pm

hello kjasper,

may I know what’s your environment setups,
could you please share several captured images through libargus to demonstrate the difference.
for your second question about system lock,
had you tried to configure the [System Settings]->[Brightness & Lock] and [System Settings]->[Power] to disable system suspend.

kjasper · May 7, 2020, 4:56pm

I have attached 2 iamges showing the difference. These were run back to back with the same settings. It looks like the black levels are different when I am setting this explicitly in libargus.
I don’t mean the screen is locking, I mean when I call jetson_clocks.sh in /etc/rc.local it doesn’t take effect.

linuxdev · May 6, 2020, 5:43pm

“rc.local” may be calling jetson_clocks.sh prior to having all cores ready or prior to being able to write to the DVFS tables. As an experiment to test if this is the case, at the end of rc.local try this, but wait a bit more than 60 seconds to test after boot:

sleep 60; /home/nvidia/jetson_clocks.sh

JerryChang · February 29, 2020, 1:58am

hello kjasper,

may I know which JetPack release you’re working with.
could you please try input some control properties, to check if you’re able to get the identical results.
for example,

gst-launch-1.0 nvcamerasrc fpsRange="30 30" auto-exposure=1 exposure-time=0.033 wbmode=2 ! nvoverlaysink

kjasper · May 7, 2020, 4:56pm

Jetpack 3.2
The images look pretty similar using that command. I am still seeing banding noise though.

I have attached 3 images taken with the lens cap on. The image contains 2 sensors side by side like this:

------------- ------------
|             |            |
|     1       |     2      |
|             |            |
|             |            |
 ------------- ------------

Each time I start the program using libargus with the same settings the amount of noise changes in each sensor. I have attached dmesg output to show my driver is writing the same settings to both sensors. Could this be a clock issue with the TX2? I am running 4096x2778 RAW12 @ 30fps streams.

hello kjasper,

these seems like power noise,
could you please also arrange your hardware engineer to check the power.
or you should contact your sensor vendor to examine your hardware.
thanks
