Role Of Vision Processing With Artificial Neural Networks In Autonomous Driving

In next 10 years, the automotive industry will bring more change than we have seen in the last 50, due to technological advancement. One of the largest changes will be the move to autonomous vehicles, usually known as the self-driving car. Scientists from many universities are striving to implement vision processing with the artificial neural network to provide driver assistance in self-driving cars.

Vision processing, as well as artificial neural networks, have been around for many years. Convolutional artificial neural networks (CNN) are sets of algorithms that extract meaningful information from sensor input. CNN’s are very computationally efficient at analyzing a scene. They are also able to identify objects as cars, people, animals, road signs, road junctions, road marking etc. enabling them to determine the relevant reality of the scene. As this system runs in real-time, the decision can be made as soon as the sensing part is complete.

One of the major steps in visual environment understanding for automotive applications is key points tracking and estimating ego-motion and environment structure subsequently from the trajectories of these key points. A propagation based tracking (PBT) method is popularly used to obtain the 2D trajectories from a sequence of images in a monocular camera setup.

The inputs from one or all of the sensors like LIDAR, RADAR, camera, IR, etc. are evaluated and decisions are taken accordingly. For example, if a car in the front suddenly brakes, the onboard computer would instantly verify the distance and calculate the speed with help of the existing sensors. Then it would apply the brakes faster than any human would be able to do. This method helps to prevent an accident with 90% efficiency.

The use of vision processing with CNN is rapidly increasing in automotive applications to enable camera-based autonomous driving. This technology sets a new driving standard. With this technology in our hand, fewer accidents, fewer fatalities, and less pollution are experienced. Vision processing in autonomous driving also enables efficient journeys, reduced crowding, car sharing, and packing cars in more tightly via vehicle to vehicle communication.

AutoPi makes your car intelligent

What if your car was intelligent like KITT in the 80’s TV show Knight Rider? With AutoPi all cars become intelligent and can have eyes, ears and a voice.

Until now all functionality and data from cars have belonged only to the manufacturers. With AutoPi the car owners can, as a cooperating community, take control over their own vehicles and data without having to be an engineer.

AutoPi.io is a Danish startup company and they have just launched their open Internet-of-Things platform for cars. It is the first extendable maker platform for cars, built on the revolutionary Raspberry Pi mini computer.

In less than 24 hours, their Kickstarter campaign has raised more than $20.000:

How to Build a Bi-Fuel (LPG & Unleaded) Trip Computer Using Arduino

Nikos Stavrou @ instructables.com build a bi-fuel trip computer using arduino and has a detailed tutorial on it. The computer can measure both LPG and unleaded fuel consumption. He writes:

The main reason I made this project is the lack of a trip computer that is designed for LPG powered cars.

I named it Bi-TripCo as it can measure the fuel consumption for both fuel systems of a Bi-Fuel car (LPG and Unleaded).

Some might say: “ok, a similar one, no big deal!”. Don’t rush.There are many (or some) tools out there, that can calculate the consumption of conventional fuel systems, which are very easy to use: just plug it into the OBD port of your car – unless you have an older car which does not have one, like mine. And, of course, there are some very good implementations based on Arduino, which can calculate many things related to the Unleaded fuel consumption. But those tools can not be used on an LPG powered car.

Shane has been working on making small robots and made a prototype of a matchbox car, a robot car that fits inside a matchbox:

This build consists of a tiny DC motors ripped from a pair of 9g servos, a h-bridge motor controller, an el-cheapo 8 bit pic and a 100mAh 3.7V LiPo battery.
