Available in two variants:

Both the Fixed-Focus and Auto-Focus variants have fixed-focus grayscale stereo cameras. The Auto-Focus vs. Fixed-Focus variants of OAK-D-Lite differ only in the 12.3 MP color camera. Fixed-Focus has the lens fixed in place mechanically and cannot move, whereas Auto-Focus has an electromagnet that controls the lens position dynamically.

• Auto-Focus can focus on objects dynamically, which is mainly useful for objects within 50cm of the device
• Fixed-Focus is recommended for heavy-vibration applications (e.g., drones, lawnmowers, bikes w/out suspension, etc. (see video)

Both Auto-Focus and Fixed-Focus can clearly see objects beyond 50 cm, working between 50 cm and infinity. Auto-Focus has the advantage that it can focus on objects as close as 10cm (see video).

Laser dot projector projects many small dots in front of the device, which helps with disparity matching, especially for low-visual-interest surfaces (blank surfaces with little to no texture), such as a wall or floor. The technique that we use is called ASV - conventional active stereo vision - as stereo matching is performed on the device the same way as on OAK-D (passive stereo).

Blanket IR LED illumination allows perceiving low-light and no-light environments. You can run your AI/CV processes on frames that are illuminated by the IR LED. Note that the color camera doesn’t perceive IR light, so you would need to use a mono camera stream for your AI/CV processes.‍
