Wide-Area Indoor and Outdoor Real-Time 3D SLAM

University of California, Berkeley
Open source code available at: github.com/erik-nelson/blam
Real-time 3D SLAM with a VLP-16 LiDAR. Point cloud resolution is 5 centimeters. Grid cells on the ground are 10 x 10 meters. No other sensors used. Loop closures are computed by ICP scan matching with scans from nearby poses, using GTSAM as a back-end.

As in the film "Prometheus" by Ridley Scott's

Hello. Very awesome job. Thanks for showing this video, and I have some questions.
In ICP algorithm there are many methods for selecting corresponding points, which methods did you choose?
How many miliseconds dose it cost for one scan matching?

It would be nice to have this equipment in Australia to trial.

[@robot3dprinting89]

Wow. That is awesome.

[@Gfish17]

its just like scanner sombre!

[@user-tj6yg7jr2m]

great job!

Hi, great video.
Can i ask, dis you use Rtab map with only a lidar and thats it?
If so this is exactly what id like to do but there are no how to... like how to get rtab to use the lidar?
I could do tjis using a kinect but it takes too long and becomes inacuate as it can create a wall map on top of an already viwed wall your trying to pass by or fill a gap in.
Any feed back on this would be great as id love to just grab my laptop, a lidar and start mapping.
Thanks

amazing

Hello Erik, I teach in Interior Design and Industrial Design and was looking into what I could do as a DIY - your results look fantastic. Would you be able to lent me some of your insight?

[@subsonictonic]

So cool

[@BrettStevens2]

you need to stick this on the underside of a hexacopter for large area mapping

[@mechanicalmonk2020]

Remember Hexacopters? What a wild time

[@ahmedwathab302]

good job ,but can you show the steps that you used to generate this map ,because i am still confuse in the steps .thank you

[@marinoramirez2137]

Awesome. Your software could works on RPLidar A1 sensor too? Thanks!

[@matthewforan281]

Sure, but that sensor is a 2d lidar so you might as well use a 2d slam library

[@lutfanmikail8375]

Hi, great work! May I know what kind of sensors (i.e. cameras) you use?

[@qur100]

VLP-16 LiDAR

[@saivenu120]

thanks for video, which software tool you used for it...example matalb or python ....like this

[@Spearmeat638]

search about ROS

[@Spearmeat638]

it works with python and c++

[@ArghyaChatterjeeJony]

Can you please tell me what was the cost of this lidar? I am searching online and as if the authority is advertising in such a way that they don't want to disclose the cost.

[@jailsontopografiaagricola5513]

Does the code work with scanner handle scanse sweep?

[@youli7339]

Thanks! What is the meaning of different colors?

[@BlissFC]

pretty sure its elevation

[@youli7339]

Hi Tyler, thanks for the replying :)

[@WaladiNurAkbar]

Can I use other Lidar devices or even Microsoft Kinect device?

[@shuyangan3892]

Waladi Nur Akbar possible, better to have a odometer as well

[@HungPham-pg6oq]

Tex routing

[@yuchengli8009]

are there any bag file that I can try this packages?

[@user-xx3qf8pk3y]

Is there any paper about this ?

[@geekhamza]

no :'(

[@GoDangDoiWorksTeam]

It using imu sensor?

[@user-lp3gz9bp1f]

no , blam has no topic accept imu data.

[@GoDangDoiWorksTeam]

张晓阳 im new on ROS, can u teach me step by step to install BLAM?

[@hab_punch]

Amazing! Thanks for sharing
