We’ve been using the ZED2i camera for industrial applications and initially had no issues when it was mounted using 3D-printed brackets. However, after switching to a mild steel (metal) mount, we started noticing significant depth inaccuracies—up to 10 cm—within our preferred depth range of 0.3 to 1.0 meters. This issue is visible even in the ZED SDK (v4.2.5). Could the metal mount be causing this problem?
Hi @Dharaneesh
Please send a picture of your metal mount.
Is it forcing the structure of the camera, causing a misalignment of the optics?
The mount seems good to me. Are the fixing holes placed correctly?
They must be precise in order to not modify the case structure of the camera…
Yes, they are precision-cut with a slotted design, so they definitely don’t alter the structure. Additionally, one of the cameras became miscalibrated simply from being used handheld near the mount, without actually being mounted.
As I mentioned earlier, the same structure doesn’t cause any issues with my 3D-printed version, but problems arise when using the metal one. Could you please look into this? More than three of my cameras have shown inaccurate behavior with this metal mount.
Hi @Dharaneesh
Please write an email to support@stereolabs.com
Please add SVO files recorded with ZED Explorer when the camera works correctly (plastic frame) and when it doesn’t (metallic frame).
It would be great if the camera points to a static calibration chessboard when recording the SVO files.
