Prakul, you need to be more specific. Do you have the image processing sorted and you are looking just for advice on the image capture stage? I can assure you of one thing - the processing is where the difficulty lies!

Chad, is your application meant to be executed in real time, or from logged images? What resolution are your source images and what do the results look like?

Thanks for your response,

Mike

Would you mind posting an introduction to your software here: http://www.pgrammetry.com/forum/viewforum.php?f=33 ?  We'd all like to hear more about what you're working on, and any progress you've made towards these problems since your post.

Hi Chad,

 

I would like to know more about your application if you dont mind, it seems very interesting.

How you do take photos using your RF, automatically or manual?

What kind of software do you use?

I have an EasyStar, 2.4 MHz Radio, and standard digital camera (7.2 Mb).

 

Best regards, Jaime

Hi Chad,

I am newbie here, so I guess a PM is an invitation, but I dont know how to confirm that.

give some indications to accept you.

I understand you use a Nikon camera, Is it heavy? do you have a strong heli engine?

what about the software to make 3D mapping?

 

Regards, Jaime

I have two 3D scanning applications. Both developed from things I found on good ol' fashioned Google.

Colin Ord's 3D scanner is pretty impressive but as its VB6 I updated it to .net 3.5 and found it to work(ish) so with some jiggery pokery I can scan accurately in realtime. Parts: Webcam, Laser, Cocktail stick.

Todd Donko's range finder is a different beast entirely. Whilst once calibrated it becomes accurate putting the scanned information together is what I have found hard. Once again I can scan in realtime but as the line should be level (like in flight) for the data I have had problems with consistency. Parts: Webcam, Laser, Cocktail stick.

Webcam sees stuff. Use a visible light filter from eBay to help with red laser work during the daytime.
Laser allows you to performance 3D mathematics. Red is good for IR capable webcams. Green is so clear for large distance scans (30m+ or out of the window in my case).
Cocktail stick (glass preferably) changes the laser dot into a laser line with 180° field so once further away scans can continue.

I am currently working on another method of scanning but playing with my plane, work and friends have all interrupted any real progress. I'm hoping to then port one of these methods into a self contained bay in my UAV (just for laughs).
