Calibration Resolution

Nerian, I wanted to ask quick if there were any recommendations as to what resolution you should calibrate the camera at? The system we have runs at 800x320 and I wasn't sure if it might be more accurate to calibrate at the highest resolution possible and then modify the yaml file to be instead for ...

Re: Parallelizing Disparity Matching and ML

I also wanted to ask, why is it that the latency does not decrease when you move from 192 max disparity to 32 max disparity?

Parallelizing Disparity Matching and ML

Nerian, Would it be possible to pass images directly through the scene scan rather than packaging them up with the disparity map after it has been processed? This would be extremely useful for anyone doing any ML/object detection on the images prior to depth estimation. Given the typical latency on ...

Re: Karmin Syncing Process

Thanks Konstantin, is it an actual synchronization process? or more of a time translation process (i.e. is it an actual clock on the cameras or is it a counter or something)?

are there any details of how this is done over USB3?

Re: Karmin Syncing Process

Hey Konstantin, what I'm curious about is how are the trigger pulses from the trigger cable (which are time stamped in terms of the SSP's clock) associated with a frame that returns via USB. Another way to ask the question would be, how are images that come immediately after a dropped frame time sta...

Re: Karmin Syncing Process

just to clarify, I'm curious as to how this is actually done (not how the user enables it)

Karmin Syncing Process

Nerian,

are there any resources available that explain the process for time syncing the karmin camera to the SSP? And also approximately how accurate it is?

Re: SSP Troubleshooting

Hey Konstantin, 1) please find a link to the bag with the failure mode here. The first 2 cones are a-okay but it is the third cone (on the left) that has its point cloud half in the background and half in the foreground. You can rviz the left_image and point_cloud topic to view. Is there anything yo...

Re: SSP Troubleshooting

Hey Konstantin, thanks for the response re issue 1: we figured out the two problems with it, for 1 (the Process stereod stalled issue) it turns out that the hardware we are using (Nvidia Jetson Xavier) has some issues with communicating with the SSP, this has been an issue we've faced for months and...
