Chinese autonomous driving company Momenta has partnered with Toyota to provide automated high-definition (HD) maps for autonomous vehicles in China.

Through this new partnership, the companies intend to promote Toyota’s automated mapping platform (AMP).

Using consumer-grade sensor sets, Momenta’s vision-based system generates HD maps with 10cm-level relative accuracy.

Momenta’s consumer-grade sensor sets consists of a camera, global positioning system (GPS) and inertial measurement unit (IMU).

The company said that its HD map creates rich geometry features such as traffic signs, poles, lane borders, traffic lights and road markings, as well as road and lane-level topology and semantic features.

Momenta’s technology processes big data through an automated mapping pipeline, enabling HD map updates with high frequency. This offers a ‘live’ reliable map for different autonomous driving modules, including localisation, planning and control.

Momenta said: “Momenta and Toyota’s cooperation will make the best of our two companies’ strengths. Our strategy is to pursue both mass-production passenger vehicles and full autonomy for mobility service vehicles.

“We are confident that the cooperation with Toyota will play an important role in this strategy.”

In April 2019, US-based Ambarella announced a collaboration with Momenta to introduce an HD mapping platform for self-driving vehicles.

The platform was designed using Ambarella’s CV22AQ CVflow computer vision system-on-chip (SoC) as well as Momenta’s deep learning algorithms.

The collaborative HD mapping solution offers mapping and localisation for autonomous vehicles, as well as map updates through crowdsourcing.
