Do you know how many tiny streets are there in an Asian Country? Yes, maybe more than millions:)
Well, how drivers can learn and keep in mind that thousands of tiny streets? Grab (A developer of a super-app for ride-hailing, food delivery, and digital payments services ) has a clever idea, and their detailed map app “Grabmap” updating and growing day by day. But how?
This is what I’m talking about!
Let’s dive in!
GrabMaps has come a long way since its inception in 2017 thanks to KartaCams—little action cameras mounted on bike helmets or car windshields. These are used to collect high-quality street-level imagery for mapmaking and are captured by driver-partners while they’re ferrying passengers or delivering goods.
KartaCams are mounted onto drivers’ helmets or car windshields to collect street imagery. Since then, They’ve deployed thousands KartaCams across Southeast Asia and collected billions of images, to make GrabMaps as precise and context-rich as possible.
The KartaCam 2 is more portable and delivers higher quality images. Early test results for KartaCam 2 have been encouraging. With its dual band GPS (Global Positioning System) module and an extendable antenna, both the position accuracy and the signal stability are much improved compared with the last generation.
In its latest iteration, the KartaCam comes in a much sleeker design, which makes it easier to carry.
KartaCam uses edge artificial intelligence (AI), a combination of edge computing and AI that brings computation closer to the devices collecting data, making collection faster and smarter.
Other key features include 4G and Wi-Fi to allow us to configure the camera remotely, AI to check image quality without having to upload all images to the cloud, and Bluetooth to pair it with a driver-partner’s mobile phone.
Kartacam360 collects panoramic images like this one.
But KartaCam only had a 150-degree view. The following year, we built KartaCam360 by piecing four KartaCams together, where images collected can be stitched together to produce one panoramic image. This enabled to gather data with a quality level comparable to that of professional cameras, yet at a cost that was 10 times lower.
Better images, Precise locations
Still using edge AI, but much more powerful, KartaCam 2 delivers images of even better quality and boasts more precise location data. It’s also more portable and more intuitive to use.
Here are some key improvements:
