Sunray ARCore?

Hi,
I haven't tried out ARCore yet, but it was reported that the precision is far less than Google Tango. But precision wouldn't be the main problem. The main problem with Google Tango etc. was the relocalization. Basically, those systems are 'visual odometry' systems - they accumulate the distance traveled. Because errors accumulate by visual odometry systems, these systems must be able to relocalize at certain places to reduce the accumulation error to zero again.
And the Google Tango relocalization (and probably the ARCore too) didn't work well with different lighting conditions. For example, once it was trained with objects (house, trees etc.) in the cloudy morning, it failed to recognize them in the evening or in sunlight. And without a robust relocalization errors accumulate and you get a precision like normal GPS (2-4 meters) with large garden environments.
I think the ultimate goal would be to robustly recognize already seen obstacles and use them to relocalize. But that's another story... (Deep learning cameras, cloud-based training, ...)

Regards,
Alexander

Sorry, but I don't believe both mentioned products actually work robust everywhere. Maybe on a flat 2D surface (and not on 3D mountains), maybe at daylight (and not at night), maybe within 50cm precision (and not 1cm), maybe with some obstacle avoidance (and not flexible obstacle path planning), maybe with random or straight line mowing (and not globally optimized mowing patterns). maybe .... Really guys, don't trust those glitter, twinkle, we-can-do-all products too much - those don't exist :) - They should show user manuals, tutorials, mowing videos, different environments, real customers, ... :)
As a customer, I would want to see the real product (without marketing hype), how it works, where it works, where it does not work (that is trust-making) - and not how nice the product or company is. I think we can all agree on that ;-)

Yes, it's like Toadi, only marketing videos. No user and independent tests, videos, testimonials. We've been there for almost a year and what we're doing is real. But there are enough people who spend a lot of money on promises and marketing talk.
