Hello! I'm new to ecosynth.org, i thought i would write a post about some interesting things i've seen lately. i apologize if i'm covering old news here. i searched around and couldn't find any references....

has anyone seen this? 3D Flash Lidar-

http://blog.lidarnews.com/lidar-for-geoint-in-real-time

http://en.wikipedia.org/wiki/3D_Flash_LIDAR

i contacted advanced scientific concepts

http://www.advancedscientificconcepts.com/index.html

to inquire about the possibility of accessing / using equipment for an art project. i'll let you all know how it goes!

also- has anyone seen this system-

http://matterport.com/

it's limited in range and ambient light conditions as well as processing time. but it's a compact system that shows promise. i think it uses commercially available sensors (like kinect), thus the problems with infrared interference. there are other sensors out there that could possibly be better applied to large field mapping. panasonic makes a product range called d-imager i've worked with. they are designed for use in day ambient light conditions....

Hi Grady, 

Welcome, and thanks for posting!  

I have heard of flash LIDAR and it seems like it does offer a powerful resource for real-time 3D color mapping - I would love to get my hands on some of that equipment for our study areas!  

At the same time though, I feel there is even bigger appeal and need for 3D remote sensing that doesn't require a full scale aircraft; the ASC video shows the flash LIDAR on a helicopter.  While the LIDAR cameras / imagers are usually pretty small (1-2 kg and getting smaller), the other equipment (GPS, inertial monitoring unit (IMU), computers, etc.) that are needed to use the LIDAR, tend to make for a very large payload (easily 5-10 kg and up).

A big appeal of using computer vision and an 'Ecosynth' methodology is that for less than $4000 (< $2000 for an Arducopter system) any individual can collect their own high-quality 3D-spectral scans when and where they want them with a small and lightweight (< 2kg) flying system.  

What kind of projects are you using this equipment for?  The Matterport and Panasonic gear seem interesting, but one thing I am always curious about is how these systems will respond (or not) to imaging vegetation. The near range systems like the Panasonic are definitely appealing for our ground-based 3D scanning work.

I look forward to hearing more about your work!

Hi,

It seems the data site of Ecosynth is down. We are trying to learn this tool to use it in our study of biomass calculations in our campus of IISc Bangalore.

It would be great if we can get access to sample dataset images so that we can understand the working of the tools as such. We shall be thankful for accessing the datasets. Kindly let us know.

Regards,
Sanjeev
