Oak-D as a linescan camera

HikerGlenn

I have an application that needs to utilize linescan video and wonder what would be needed to have the Oak-D Lite prepare the linescan by either snipping a single vertical line and sending that or converting the linescan to video frames where each frame moved the prior image left one pixel and then appended a vertical scan line from the camera on the right side. Any advice on how this can be accomplished would be appreciated.

Hi,

Have you had any luck with the line scanning application? I just posted a near identical question before seeing yours.

Not as yet. I found a few python apps that do rudimentary linescan with opencv which would work with Oak-D when it acts like a webcam. I'm hoping to find time this winter to see if an Oak-D app can be done which just returns the single line to reduce bandwidth and cpu overhead. But, for my application I really need optical zoom so something like a DSLR may be the solution but would be overkill for getting a single scan line. If you come up with something please let me know! Where did you post your question? I'd like to follow it too.

Thanks for the reply,

Re-reading your post, I’m not sure if we’re after the same thing or not. Here is the link to my post:

https://discuss.luxonis.com/d/892-line-scanning-for-2d-depth-profile

I am trying to pull X and Z spatial coordinates for a horizontal strip across a depth frame, allowing me to plot the 2D cross-section of that slice. Had some luck with shifting the roi over with each new frame, but would prefer to pull the whole set of coordinates from a single frame.

Sound anything like your application?

I have created a simple multi-ROI spatial location calculator example, see PR here. I hope this helps!
