Am going to be competing in Robocup Rescue in Thailand next year - I was too busy to pull off a campaign for Brazil this year :(

Will be using CUDA powered GPUs, Kinect/Xtions, and ROS as the primary navigation system, but I need a sensor for long range scanning - at least 25 meters. It is probably overkill for the competition, but I want it to be used in other real world applications. It will need to be very robust, fairly light, high resolution, and proven. The cheaper the better, but high quality is a must.

Have read this question, but I need something that is available and proven now: What different sensing approaches are used in the current batch of indoor 3D cameras?

A similar question was asked before, but closed: LIDAR solutions. The suggestion was good , but I need something with a lot more range:

At the moment am probably going to go with a the RobotEye RE05 or RE08 3D-LiDAR:

Here is a paper that descibes how this sensor can be used on a mobile robot: www.araa.asn.au/acra/acra2012/papers/pap125.pdf

Does anyone have any alternative techniques, or suggestions of a sensor that can achieve similar results?

If cost is a factor, you can also do 3D reconstruction using stereo vision with a pair of commercial digital cameras. Many algorithms are available online to reconstruct 3D scenes from a pair of stereo images since this is a popular research topic.

The quality and range of the reconstructed scene will be a function of the image resolution, the image distortion, and the spacing between cameras.

  • $\begingroup$ Thank you for the answer notAlex. I have been playing around with stereo vision for many years, the Kinect is basically doing that actively with IR. I need to also scan in the absence of light, 2 vision cameras probably won't suffice. I would need to do some serious R&D to get it to the quality I need, If I were to go down that path I would go probably go with one of these, but it is still EUR 4,000. $\endgroup$

For the stereo vision, it could be very hard to achieve a resolution over 1% I think, which means 10cm resolution can be achieved for 10m range..

Roboteye RE05 seems to be a good option.. However where to buy one?
