fresh system uses onboard cameras in addition to GPS to create accurate map
The Japanese the said the fresh system – which gathers data via production vehicles as opposed to the traditional method of using specially built vehicles equipped with 3D laser scanners – will help the safe introduction of automated driving.
The road images in addition to vehicle position information gathered via cars can be sent to data centres where the item can be automatically pieced together, corrected in addition to updated to create highly accurate maps that will cover a wide area.
Automated driving systems will need an accurate understanding of road layouts in addition to traffic restrictions, speed limits in addition to signage. Also, precise measurement of vehicle positional data requires the collection of information on dividing lines, kerbs in addition to various other road features.
Using the traditional (in addition to more costly) method of mapping via 3D laser scanners data has to be manually edited to add information on road features, such as kerbs, divides in addition to signage. The data collection can be infrequent, so the maps are not updated regularly in addition to their usefulness can be limited.
Toyota’s fresh system uses automated, cloud-based spatial information generation technology to generate high-precision road image data via the databanks in addition to GPS devices used by designated vehicles.
There can be a higher risk of error having a system that will relies on cameras in addition to GPS in that will way, compared with one that will uses 3D laser scanners, nevertheless positional errors can be mitigated by using image matching technologies that will integrate in addition to correct the road image data via multiple vehicles, as well as high-precision trajectory estimation technologies. that will restricts the margin of error on straight roads to a maximum of 5cm.
By using production vehicles in addition to existing infrastructure to collect information, that will data can be updated in real time. the item can also be implemented in addition to scaled up at a relatively low cost.
Toyota plans to include that will system inside automated driving systems that will will be available in production vehicles by around 2020. While initial use can be anticipated to be limited to motorways, the item will work on expanding the item to cover ordinary routes further into the future.
