Principal Computer Vision Scientist NVIDIA

How to Train Your Self-Driving Car!

Scribe: Sam Peterson Introduced by: Kaj Pedersen

Rich Martin began the morning with a prayer.  Jim Gordon then led us in the Pledge of Allegiance and introduced our guest Quincy, Andrew Face’s daughter.

Tonya Franzen-Garrett made an announcement about the adoption party and how we are in partnership with the Bellevue Noon Rotary who also does an adoption party.  Their party is on March 23rd.  They need drivers.  She reminded us that the Noon Club helped our club and we should return the favor.

Wendi Fischer then asked some of the newer members to come to the front of the room to play a game.  The members told the audience their names, occupation, and what they were involved with in the club.  The audience then got to guess each newer member/contestant’s dream job.  This was a fun ice breaker that caused a few laughs.

We then recognized some Birthdays and sang Happy Birthday to Laura Cosacchi.

Chris Boland then reminded all of us to park in the top lot.

Wendi Fisher made an announcement to have all red badge members gather at the end of the meeting to review the necessary steps in order to obtain a blue badge.

Kaj Pedersen then introduced our guest speaker Michael Kroepfl.  Michael is a Principal Computer Vision Scientist at NVIDIA.  The topic was “How to train your self-driving car.”

Michael presented a slide show and started out with a picture of Kitt, the car from the 1982 show Knight Rider.  This was the vision back then.  Some of the features Kitt had were:

  • Instrument panel
  • Turbo Boost
  • Computer AI with personality
  • Voice Synthesizer, etc.

He then pulled up a picture of a modern Tesla.  The slide was called “2019 Reality Check.”  Some of the Tesla features were:

  • Microsoft Cortana
  • No Turbo Boost
  • Built in Vacuum, Radar, etc

Michael then described the different levels, 0-5, of “Human vs Machine”.  Level Zero means no active assistance system for the vehicle.  Level 5 would be no driver and fully automated.   Hands off and eyes off the road vehicles such as today’s Tesla’s are a level 3.

Autonomous driving requires sensors and algorithms.  Some of the features are camera based perception, ultrasound, radar, lidar, IMU, GPS and odometer.  Lidar based mapping and localization is also used.  Engineers learn from video games (virtual vs real world).  Simulating is important before real world driving.

Michael wrapped up his presentation with some of the following Questions and Answers:

  1. When will cars be driving automatically? A:  Not yet primarily due to the cost which is estimated at $500,000 for a car.
  2. Who will win the race? A:  Not sure as many companies are working on this.
  3. How do AV vehicles work in the snow? A:  Engineers are still working on this as snow flakes are difficult for the sensors.
  4. When will Artificial Intelligence completely take over? A:  Nobody knows.

Chris Boland then closed the meeting with the thought of the day.
