Grabbing Zivid data in halcon takes at least 2.5 sec more then the Zivid studio

[HM102]

I am using the provided code to grab the zivid data:

info_framegrabber ('GenICamTL','device', Information, Devices)
get_first_available_zivid_device (Devices, Device)
open_framegrabber ('GenICamTL',1, 1, 0, 0, 0, 0, 'progressive', -1, 'default', -1, 'false', 'default', Device, 0, 0, AcqHandle)

This code takes at least 2.5 sec more the the zivid studio.

Is there an option or parameter in the framegrabber to make it faster?

It is expected that the first time you connect to a camera takes time; see from our Changelog (for SDK 2.7): _* The connection time to the camera is increased, due to initialization of the compute pipeline:

• The first time a camera is connected to in a process can take 6-10 seconds longer than in SDK 2.6.
• This increase in connection time will only happen once per camera model, per Zivid::Application object._ source: https://www.zivid.com/hubfs/softwarefiles/releases/2.8.1+dd4dffea-1/Changelog.md

Also, we know there is some overhead when using GenICam for Halcon. You could be right that it is consistently 2.5 seconds slower to connect to a camera in GenICam compared to SDK/Studio. It could also be that it is not consistent; in general, in SDK/Studio, it takes 10-20 seconds depending on the PC, and on the same PC it could be +/- 2-3 seconds around the average connection time.

In general, we recommend using .hdev (via GenICam) for development, but C++ or C# (Zivid SDK + Halcon SDK) for deployment/production. This is because using Zivid SDK+Halcon SDK is faster and also because not all Zivid SDK features are exposed via GenICam (for example CaptureAssistant and Capture2D).
