Hokuyo Range Finders + 3D mapping

Help & Support Robot Parts
1

I am considering your Hokuyo sensors, probably the UTM-30lx for environment mapping on a mobile robot I am building. I was wondering is thise sensor only scans on one plane of if there is a way to make it scan to make a 3D image of an environment. I saw some something about this before but can’t find it anymore.

Any ideas?

That is exactly what i was looking for Coleman, thanks!

Thank you for your interest Gardangel. This project has the purpose of mapping an environment in 3D, possible uses include mapping of office buildings to even exploring cave systems, where humans don’t want to go. The office will be a good start though!

Wow, impressive. I’m sure the price is cheap for this kind of object. If you want to build something with that, you have the money to make something really cool… Do you have extra money for me pleaaase ? :smiley:. I’m joking. But I want to know what you’re doing exactly for your project. You get my interest ! A kind of weapon maybe ? If you need a reasonnable good coder, I can help you… Well, after 10 years, I think I’m good with it.

Please, tell us what you’re doing, I want to know for sure.

Greetings!

I will make an application about 3d mapping with Hokuyo ange finder.

I am thinking to use the URG-04LX-U​G01.

Before purchase the product, I want to be sure exactly what I need.

Will we be able to make 3d mapping with Hokuyo URG-04LX-U​G01 ?

Which steps should I follow to obtain 3d mapping ?

Best Regards

Hi Richard,

Although the scan is two dimensional, you are free to add motion along a third axis (cartesian coordinates) in order to get a three dimensional image. We are also aware that it may be possible to rotate the Hokuyo scanning laser rangefinders about an axis to get a 3D image (this would require polar coordinates) of an environment.

Alternatively, you can keep the scanner in one direction (vertical for example) and rotate an object on a turntable to get a 3D image. Adding a third axis or an actuator makes these products incredibly versatile - not only for environment mapping.

Hope this helps,

Hi Shakesmeare,

Welcome to the RobotShop Forum. The Hokuyo Laser Rangefinders such as the URG-04LX-UG01 can give a 2D map with the software provided. If you want to go 3D, you will need to add a degree of freedom and either adapt the software or write your own code. There are many options such as:

  1. Tilt the unit
  2. Lower / raise the unit vertically
  3. Rotate the unit
  4. etc.

Hope this helps,
