Britain looks to standardize HD maps for autonomous vehicles
With the development and testing of autonomous vehicles gaining momentum, the demand for HD-mapping is soaring but there seems to be a lack of consensus, standardization, and collaborative initiatives.

A new report by Zenzic, the UK hub organization for self-driving vehicle development, and Ordnance Survey (OS), Great Britain’s National Mapping agency, lays down global standards for HD-mapping, which is crucial for autonomous vehicles.

The report titled ‘Geodata report – analysis and recommendations for self-driving vehicle testing’ proposes creating common data standards for HD-mapping to foster collaboration and boost public confidence in the authenticity of mapping data.

Fooling LiDAR, the auto-drive failsafe | RNTF Jul 2019
"In the experiments researchers succeeded in creating undetectable targets, exposing vulnerabilities in LiDAR detection systems through an evolution-based black box algorithm."

"Last summer we saw a paper from researchers who spoofed all the GNSS constellations at once, and at the very modest price of $400. – If you are on a fixed income and $400 seems to be a lot, think about the tens of billions of dollars invested to produce GNSS signals.

The next month we saw a paper from researchers who decided that spoofing the signal might not be enough to mislead a vehicle driver. So they figured out how to also send a false map that looked like were the driver was, but, along with spoofed GNSS signals, would help misdirect the target vehicle. Just perfect for kidnapping, stealing cargo, or luring a driver into some other dangerous situation.

This summer we saw a paper from Regulus that reported on their ability to cause a Tesla in auto-drive mode to suddenly brake, accelerate, and exit the highway early and at the wrong point (we understand their co-worker in the car was scared silly). Thanks to the car’s LiDAR (a radar-like sensor), they were not able to direct the car off the road.

Below is a report on a paper that shows that LiDAR, which many are regarding as the automated driving fail-safe, can also be fooled."
