For the depth sensing, what is the range for the ZED cameras in terms of measuring distances and the accuracy of the detection?
Last updated: October 23, 2026
All ZED stereo cameras use passive stereo vision combined with the AI-powered Neural Depth Engine of the ZED SDK to estimate depth. The depth range depends on the camera model, the stereo baseline, and the focal length of the optics.
The table below summarizes the depth specifications of each camera model and lens option, as reported in the official product datasheets:
Camera model | Optics (focal length) | Baseline | Depth range | Ideal range | Depth accuracy |
|---|---|---|---|---|---|
Wide, 2.2 mm | 120 mm | 0.3 m to 20 m | 0.3 m to 12 m | < 0.8% at 2 m, < 4% at 12 m | |
Narrow, 4.6 mm | 120 mm | 1.0 m to 35 m | 1.0 m to 20 m | < 0.4% at 2 m, < 7% at 20 m | |
Wide, 2.2 mm | 50 mm | 0.1 m to 8 m | 0.1 m to 4 m | < 1.6% at 2 m, < 3% at 4 m | |
Narrow, 4.6 mm | 50 mm | 0.15 m to 12 m | 0.15 m to 6 m | < 1.0% at 2 m, < 3% at 6 m | |
2.8 mm (fixed) | 18 mm | 0.03 m to 2 m | 0.05 m to 1.5 m | < 0.2% at 0.05 m, < 1.2% at 1.5 m | |
Wide, 2.1 mm | 120 mm | 0.3 m to 20 m | 0.3 m to 12 m | < 0.8% at 2 m, < 4% at 12 m | |
Narrow, 4.6 mm | 120 mm | 0.5 m to 35 m | 0.5 m to 20 m | < 0.4% at 2 m, < 5% at 20 m | |
3.06 mm | 63 mm | 0.1 m to 15 m | 0.1 m to 9 m | < 1.0% at 2 m, < 1.8% at 4 m | |
ZED 2 (legacy) | 2.12 mm | 120 mm | 0.3 m to 20 m | n/a | < 0.8% at 2 m, < 4% at 12 m |
Notes:
The depth range is the maximum range supported by the camera; for the best accuracy, we recommend working within the ideal range.
Stereo depth error grows quadratically with the distance: the accuracy values above are specified at the reference distances reported in the table and degrade beyond them.
The minimum and maximum distances used by the ZED SDK can be configured with the
depth_minimum_distanceanddepth_maximum_distanceinitialization parameters; see the Depth Settings documentation.For custom baselines and extended ranges, a virtual stereo system can be built using two monocular cameras of the ZED X One family (ZED X One GS, ZED X One S, or ZED X One Core); the resulting depth range depends on the chosen baseline and optics. See Setting up your Stereo Rig with two ZED X One cameras.
