When can we expect camera triggering SDK release?

Software

One of the systems I am designing is heavily reliant on the ability to strobe lighting in sync with the camera, which means triggering the ‘shutter’ directly rather than using sl.grab. This feature was our primary reason for purchasing the zed-x cameras and the lack of it is causing serious headaches. Can you please provide a timeline for when this functionality will be available?

Hi @multicore-manticore
the external sync feature will be initially added to the new version of the GMSL2 capture card (4x inputs and 1x input) that will be released in Q4 2023.
We will also release an updated version of the 2x inputs card with this feature.

Will there be a software-based feature to allow for camera triggering before then?

As I understand it, sl.grab fetches the ‘latest’ frame from a constant feed at a known frame-rate. By grabbing a frame and noting the timestamp, we should be able to predict all future timestamps. Would we then be able to specify grab to fetch a frame with a specific timestamp rather than the ‘latest’?

I’m sorry, but this option is not available in the SDK.

I see that there are new capture cards available in the store now. Do these cards support external triggering of frame grabs now?

ie, if I were to purchase a replacement GMSL card, would I finally be able to trigger image capture, or would I still be reliant on sl.grab, and pre-fetched frames?

The feature will be released in Q1 2024 with the final launch of the new GMSL 2 Mono and Quad capture cards.
More information to come.

@Myzhar Hi, may I know the estimated timeline for this feature? We need this feature as soon as possible to continue our development and testing.

Hi @Alex-Beh
Welcome to the Stereolabs community.

We plan to release this feature in March 2024, along with the first batch of Quad and Mono GMSL2 capture cards.

Is the trigger function released too? I didn’t see it in the release notes for the new 4.1 SDK

@Myzhar any updates on this? I just got the Mono GMSL2 capture card and am waiting on this

The ZED Link Mono and the ZED Link Quad capture cards can now work as master emitting a pulse when images are acquired.
You can find the related documentation online.

Slave mode is not yet available because it requires more work. We will update the documentation as soon as it will be ready.
