D415 depth error, not matching with color image

Hi,

we are using mutiple D415 cameras connecting to one pc, usually working fine. lately we found several sensors collect incorrect depth map Irregularly, about 10 times in last 3 month. see this image set.

as you can see, the color image is correct. but for unknow reason the depth map is not matching.

after reinitializing the sensor, it gets correct.

extra info.

* we are using color 1920/1080 depth 1280/720, 6Fps

* sensor connecting to pc using usb extension cables and hubs

what could be the issue?

There was a similar case to yours a couple of days ago, where a RealSense user had been using multiple D415 cameras for a while and then the depth on some of their cameras started having problems. In the end, they found that updating their cameras to the latest 5.10.3 version of the firmware helped.

Hi,

After update the firmware to 5.10.3, our system still has problem as follows.

Both normal and error are streamed same time. Our system uses RGB and DEPTH except IR data.

our system streams 3 frames from every sensor at once scanning.

Looking at error depth image, Depth output seems to freeze.

What causes this issue?

Streaming is not stacked. I think there is some trouble in depth system.

With your multiple camera setup, are you using hardware sync cables?

If you are, if the sync cables are long (for example, 3 m or more) then electrostatic discharge can cause a reset of the counters. The D415 model is more vulnerable to this problem than the D435.

In this case, I don't use synchronous trigger.

Every sensor is free_running. Because the object doesn't move, and very short scanning time.

I should use synchronous trigger if the object move and the scanning time is long.

e.g.

Do you have any way to let the Depth sensor restart image capturing?

If you are writing your own application, you can put a hardware_reset() instruction near the start of your script, and this acts like an automated USB unplug-replug of the camera to reset it.

Thank you for information. I will discuss with software engineer about that.

Hi Fayefaye_Li,

 

 

Thank you for your interest in the Intel RealSense D415 camera.

 

Did you try updating the cameras to the latest 5.10.3 firmware version? Did it solve your issue?

 

 

Regards,

 

Alexandra
