Methods and Software used for stand counts

Posted by matemm06 on December 30, 2014 at 1:32pm

Hello,

I was wondering if anyone could share their experiences with estimating populations on photos they've taken with UAVs.  Software or particular methods that you have found to work.  I currently use a Y6 tri-copter from Event 38 with a GoPro Camera as well as a Canon SX 260 converted to near-infrared.  I've used Agisoft Photoscan with great success in photo-stitching and dronemapper. I've dabbled with Fiji/image j, and Microsoft ICE but I've found they seem to have more of a learning curve for me.

Any ideas if population estimates work well in any of these programs or in others that I have not mentioned?

 

Thanks!

      Hello Taylor,

      Do you have any news about the commercial license of your software?

      Regards,

      José Gaspar.

      Very good your work Taylor

      Working in Brazil with sugar cane if you are interested in testing their software, I have some mosaics on different dates.

      Hi Martello,

      I just sent you a direct message through the forum. I'd be very interested to see the mosaics you have and see what kind of results we can get.

      Hi Taylor,

      I have images of oil palm crops - both in RGB and NiR-GB. Can I share it with you so that you can count the stands as well.

      best regards

      Nasruddin

      Hi Nasruddin,

      I can't direct message you since we're not friends yet on the site. So I'm posting a reply here before I forget.

       I'd be happy to take a look at your images. You can email them to me if they are small enough, or send me a link from dropbox, google drive, etc. if that is more convenient. Email: tcg [at] precisionsilver.com.

      best

      Hi Taylor,

      These look great!  Very interesting work.  I don't think I have a full mosaic that is at quite that level of detail right now.  Next season I will be sure to check out my Field of View setting and check how vibration is to get a better image.  Hopefully I can pin down the best flight methods to get useable photos for this application, and I will let you know when I do.  I'd be very interested to learn if/when your program becomes commercially available. I will send some more images as they come, and as I find them.

      Thanks again for taking a look I really appreciate it!

      You're welcome, and thanks again for providing the images. Keep in touch!

      This is great. Can you create a shapefile with points for each plant detected?

    • Taylor Glenn > Eric Coronel January 13, 2015 at 7:43am

      Hi Eric. Sure, that can be done. It requires having geo-referencing for the image/mosaic, so this usually means a GeoTiff file as opposed to just a .jpg. And if you want the coordinates to be really accurate you need to do some extra work in image acquisition/mosaic-ing.

      Taylor: very interesing work, I was thinking how to count plants with images, your program is commercialy available?
