Hi, I compared two OAK-D Pro W(ov9782). The sencond one has some issue with its depth performance. please check it out and guide us to enhance its performance. And both of cameras was working same distance, position and time (1 minute later). **First camera: it seems normal working)** [URL=https://i.imgur.com/h0D09Uk.png][IMG]https://i.imgur.com/h0D09Ukh.png[/IMG][/URL] **Second camera: it seems not ok with depth performance** [URL=https://i.imgur.com/Z99DMjj.jpg][IMG]https://i.imgur.com/Z99DMjjh.jpg[/IMG][/URL] **And they are working with same code below.** depthai-python\examples\StereoDepth> python.exe .\depth_preview.py Best regards, Ryan.

Hi @"RyanLee"#p6088 , Seems like the calibration is way off on the second OAK. Could you perhaps try to [recalibrate it](https://docs.luxonis.com/projects/hardware/en/latest/pages/guides/calibration.html)? Thanks, Erik

Hi,

I compared two OAK-D Pro W(ov9782). The sencond one has some issue with its depth performance. please check it out and guide us to enhance its performance. And both of cameras was working same distance, position and time (1 minute later).

First camera: it seems normal working)

Second camera: it seems not ok with depth performance

And they are working with same code below.

Hi RyanLee ,

error: (-215:Assertion failed) sz.width % 2 == 0 && sz.height % 3 == 0

Looks like color image (NV12/YUV420) size isn't ok - either width/height isn't divisible by 2. We will take a look at it.
Thanks, Erik
