The Benefit of Stereoscopic Vision for Autonomous Vehicles

Nov 18, 2020

Currently, the auto industry is

undergoing an evolution to vehicle autonomy. And with the emergence of

technology companies in this sector, innovation is happening at an

unprecedented rate. Currently, vehicles are equipped with partial autonomy

capabilities – specifically, they are able to maneuver on their own in highway

settings (in the presence of a human driver).

The next logical step will autonomous

driving in urban settings (again, in the presence of a human driver). However,

maneuvering in cities is a complex, and thus expensive, problem to solve.

Autonomous vehicles (AV) must take into account a plethora of new variables,

including traffic lights, vulnerable road users, and constant changes in speed

and traffic density. As a result, the industry has hit a barrier with highway

autonomy – there is simply nothing on the market today that can enable urban

vehicle autonomy.

A major reason as to why the

industry is stuck at highway autonomy is due to the current unscalable sensor

configuration that is driving in cities. Presently, to capture image data, eight

monochromatic cameras are mounted on various places around the car. Given that

there needs to be two sources of depth information – along with a RADAR

adjacent to each image sensor, there must be a single LiDAR integrated onto the

car. The total cost all of this, mostly due to the costly LiDAR, is [around

$8000](https://www.forbes.com/sites/forbestechcouncil/2020/10/26/how-to-practically-enable-vehicle-autonomy-in-urban-settings/?sh=3b1396573234).

Alternatively, one can replace the

monochromatic cameras with stereoscopic image sensors, which also act as

sources of depth information. As a result, the costly LiDAR becomes obsolete –

it can be eliminated. With solely stereo cameras being used in conjunction with

the same RADAR configuration elaborated upon above, the total cost of the

system is much cheaper than the current, unscalable configuration. This newfound

scalability will allow car OEMs to make the smooth transition to urban autonomy

as the industry evolves, allowing them to be competitive in the long run.

Unfortunately, today, there is no

platform capable of processing stereoscopic image data. Solutions in cars today

are based on legacy technology originally developed for different use cases.

Because of their constraints, they are not purpose-built for the monumental

task of self-driving. A novel product must be integrated into vehicles to allow

them to process stereoscopic vision, therefore enabling advanced autonomous

capabilities in a scalable manner.

To process image data from

stereoscopic cameras, an AV must be equipped with a platform that generates a

minimum of 75 Tera-Operations-Per-Second (TOPS) per watt of power consumption. We

@ Recogni are developing a solution with such capabilities. Through leveraging

key innovations in ASIC architecture, AI, and mathematics, our product has

unmatched capabilities, at 100 TOPS per watt. As a result, we can enable

urban autonomy in a practical manner through our ability to support the

functioning of stereoscopic image sensors. OEMs should integrate our product into

their vehicles to adapt with the evolving market and enable urban autonomy.
