Google is updating its augmented reality SDK so that phones with dual cameras can catch better depth info. As noted by Android Police, the most recent upgrade to the Google Play Services for AR app, which is how Google distributes ARCore features, now notes “Dual cam stereo depth on supported gadgets” in its changelog.
In the meantime, it appears that the support will be restricted to Googles own Pixel 4 and Pixel 4 XL, which were both launched in 2019. The list of suitable ARCore gadgets on Googles developer site states that double video camera support will roll out in the coming weeks.
Notably, this means that the Pixel 5 and 4a 5G, both of which are 2020 Pixel phones with double cameras, wont see the advantages for now. That might be since their secondary cameras are ultrawides instead of the Pixel 4 and 4 XLs telephotos, which would have implications for how they could produce more detailed depth maps.
In any case, its another consequence of Googles indecision on Pixel camera lenses. The company long firmly insisted that it just needed a single electronic camera due to computational functions like Super Res Zoom on the Pixel 3, then confusingly added a telephoto lens on the Pixel 4 anyhow, then backtracked and switched it out for an ultrawide on the Pixel 5.
