Subaru’s EyeSight and the Drive pilot system in Mercedes’ EQS, among others, use stereo vision systems deployed in tighter formations to negate that – though they do also work in tandem with radar. They can potentially fall out of alignment owing to road vibrations and temperature shifts in the chassis this poses a problem when the cameras need to maintain an alignment within one-100th of a degree. The challenge, he says, is that stereo vision cameras spread farther apart present their own challenges, he says. Apart from aligning cameras with the sideview mirrors, he says placing cameras near the headlights can also work well, particularly for off-road vehicles.

While Rosen has not examined the Tesla system himself, he says that cameras that sit too close together find it harder to accurately gauge longer distances.

Tesla places the three cameras in its tri-focal system close to one another just behind the windshield, in a setup similar to how manufacturers equip smartphones with long-range telephoto, wide-angle and ultra-wide-angle lenses.

By developing a 3D camera system that sees farther and more clearly, it could help autonomous driving systems better assess the environment up ahead, says Brad Rosen, Nodar’s chief operating officer. Nodar is a Massachusetts-based startup working on Hammerhead 3D, its own proprietary camera system named for the hammerhead shark, the animal considered to have the best depth perception because of how far apart its eyes are situated. While there is no consensus among experts, some vehicle camera system vendors believe they have the cutting-edge technology needed to close the gap and avoid collisions, particularly with stationary vehicles or objects.

It was a surprising move that raised questions about whether a purely camera-based system could offer the same level of safety and performance.
