Approaches to autonomous driving range from just cameras and computer vision to a combination of computer vision and advanced sensors. He also explained why Tesla is in the best position to make vision-based self-driving cars a reality. Gave a talk at CVPR over the weekend on our recent work at Tesla Autopilot to estimate very accurate depth, velocity, acceleration with neural nets from vision.
Deep neural networks are one of the main components of the self-driving technology stack. Neural networks analyze on-car camera feeds for roads, signs, cars, obstacles, and people. But deep learning can also make mistakes in detecting objects in images. Lidars provided added information that can fill the gaps of the neural networks. However, adding lidars to the self-driving stack comes with its own complications.
It is extremely difficult to create a precise mapping of every location the self-driving car will be traveling. Tesla does not use lidars and high-definition maps in its self-driving stack. The self-driving technology must figure out where the lanes are, where the traffic lights are, what is their status, and which ones are relevant to the vehicle.
And it must do all of this without having any predefined information about the roads it is navigating. Karpathy acknowledged that vision-based autonomous driving is technically more difficult because it requires neural networks that function incredibly well based on the video feeds only.
With the general vision system, you will no longer need any complementary gear on your car. And Tesla is already moving in this direction, Karpathy says. But it has recently started shipping cars without radars. The main argument against the pure computer vision approach is that there is uncertainty on whether neural networks can do range-finding and depth estimation without help from lidar depth maps.
They decided to treat the challenge as a supervised learning problem, in which a neural network learns to detect objects and their associated properties after training on annotated data. To train their deep learning architecture, the Tesla team needed a massive dataset of millions of videos, carefully annotated with the objects they contain and their properties. With millions of camera-equipped cars sold across the world, Tesla is in a great position to collect the data required to train the car vision deep learning model.
The Tesla self-driving team accumulated 1. But labeling such a dataset is a great challenge. One approach is to have it annotated manually through data-labeling companies or online platforms such as Amazon Turk. But this would require a massive manual effort, could cost a fortune, and become a very slow process.
Instead, the Tesla team used an auto-labeling technique that involves a combination of neural networks, radar data, and human reviews. Since the dataset is being annotated offline, the neural networks can run the videos back in forth, compare their predictions with the ground truth, and adjust their parameters.
All of this improved the precision of the labeling network. According to videos Karpathy showed at CVPR, the object detection network remains consistent through debris, dust, and snow clouds. Karpathy did not say how much human effort was required to make the final corrections to the auto-labeling system. But human cognition played a key role in steering the auto-labeling system in the right direction. While developing the dataset, the Tesla team found more than triggers that indicated the object detection needed adjustments.
These included problems such as inconsistency between detection results in different cameras or between the camera and the radar. They also identified scenarios that might need special care such as tunnel entry and exit and cars with objects on top. It took four months to develop and master all these triggers. The Tesla team went through seven iterations of data engineering. They started with an initial dataset on which they trained their neural network.
They then deployed the deep learning in shadow mode on real cars and used the triggers to detect inconsistencies, errors, and special scenarios. The errors were then revised, corrected, and if necessary, new data was added to the dataset. So, the architecture can better be described as a semi-auto labeling system with an ingenious division of labor , in which the neural networks do the repetitive work and humans take care of the high-level cognitive issues and corner cases.
