missing PacketDelay in Gentl with Lucid Camera

4 次查看(过去 30 天)
Hi,
I am able to run Lucid vision camera using Gentl driver.
however, I am not seeing the field 'PacketDelay' in the src structure.
On Lucid software, i can set this using parameter called 'Stream transmission delay'
That is set to 0, and the image looks garbled and broken. I have to set a delay to make it work.
But in Matlab I have no such option
Is there any way I can get this variable to show up on the matlab video object?
I have reached out to the vendor but I am told this is Matlab issue
Is this something in the API that I need to change?
Any help is appreciated

Bump?
I have more information...
Lucid team identified a problem with Matlab reading LUCID camera features. They have done the following steps:
- performed test with the latest version of Matlab:
imaqhwinfo
ans =
struct with fields:
InstalledAdaptors: {'gentl' 'gige'}
MATLABVersion: '9.13 (R2022b)'
ToolboxName: 'Image Acquisition Toolbox'
ToolboxVersion: '6.7 (R2022b)'
- using Matlab's gige AND gentl adapter:
Matlab gige adapter does not seem to read any camera node names starting with Gev including GevSCFTD, and incorrectly parses several Stream Channel nodes (highlighted in bold).
>> vid = videoinput("gige", "1", "Mono8")
>> src = getselectedsource(vid)
src =

- tried to reproduce the issue accessing and parsing LUCID XML on other third-party software, such as NI Max, Matrox, Peora without issues.
I hope this gets fixed.
