Google's automatic driving car processes 1 GB per second of data, this is the world seen from Google car

An image showing how much data is processed by Google 's fully automated driving car (self driving car) when curving and how the world is being viewed and analyzed is posted on Twitter.

This is the keynote speech for the event "Embedded Linux Conference 2013", the content that Andrew Chatman, who is in charge of automatic driving cars, made a presentation and said what it said. Below are the contents and movies of the keynote, but you can see that it handles a huge amount of information due to only one move "turning to the left".

The title is "Google's automatic driving car: About technology and performance, challenge"


The number of traffic accidents occurred in the United States in 2010 was 5,419,000. The number of injured people was 1,542,000 and the dead were 30,196. 93% of accidents are caused by human errors.


The average work time for American workers is 26 minutes. With an average of 200 hours, considering that 150 million workers are commuting in the same way, the total commuting time is over 30 billion hours / year. Of that, I spend 4 billion hours in transportation.


So, what Google thought was an automatic driving car that human beings do not have to drive. Development has been in progress since 2009.




Google's approach is divided into four stages


First step is to make a car. Various equipment is attached to the automatic driving car


Inside of the car, like this, the driver's seat has a handle like a normal car, but the passenger side has a display for soft operation etc. attached.


The OS uses a lightweight Ubuntu.


The second stage of the approach, "Find the car". In the world where there is nothing at the beginning, there is only the data of the car in the world.


I will use the GPS to superimpose the map there.


Information on what the lane is like is added. With this, it is possible to run on an unmanned road.


Phase 3 "Perceive the world". A state like a sim city that the road exists but nothing is running, can not be reality. We will incorporate information such as what is in the neighborhood, what is happening to the signal, how the traffic jam situation is.


Finally, you can finally enter the fourth stage "Move the car". Based on information such as road conditions and surrounding environment, we decide to "run this route".


The curves are processing information such as the radius of curvature, the speed at which to enter, the color of the signal and the location of the stop line.


The overlapping map is not just a road map, but also height information. Basically it is said that people's hands are working with the help of computers.


Indeed, on the car, create a surrounding pixel map like this. This is a bird's eye view ... ...



Obviously it becomes necessary to look down from the oblique view.


I can see how the topography around the road is like this from the car.


Although this is going up a winding pass road, it is easy for the radar to grasp the situation at the front, so the running speed is relaxed.



Location where pedestrian is forward. I am running following the former vehicle (green shadow) ......


As I approached the pedestrian crossing, something (shown in yellow shadow) that is not a car came across and stopped.


It seems that this is grasping the running on the expressway from the sky. The truck running behind has passed and we are slowing down the speed a bit because the distance between the car and the front is obstructed.



Lane tracking, this isRound aboutRunning.


Stop at the intersection. You can see that pedestrians are traversing or are grasping cars trying to turn left or right at the intersection center.


The amount of data processed by the automatic driving car seems to be as much as 1 GB per second, but by doing this, we realize "automatic driving" without human hands.


When will we be able to ride an automatic driving car in Japan, when will it be around?


· Bonus
Automatic driving car-like car that everyone in New York finds and is taking pictures. I just thought that it was "Google's automatic driving car!", But it is an ordinary car that is made to look like that.
