The Great Candle Act:
Screenshot of my program:
Hi everyone! I’ve just made the most exciting thing I’ve ever made in my whole entire life. Yup, it’s the laser guided camera panner I was talking about! I’ve increased the angle of rotation of my ol’ parallel port controlled floppy drive camera panner by making some small mechanical adjustments. I’ve written a program which captures images from my webcam and scans those images for the brightest pixel. This bright pixel is usually a laser dot in this experiment. After finding the laser dot, it determines its position and moves the floppy drive stepper motor to turn the camera towards it. Check out my YouTube videos above to see it in action!
Since my code searches for the brightest pixel, it even works with candle light. Not only that, it can also track infrared light (which is invisible to the naked eye!). I used my TV remote as an infrared light source, and my camera tracked it quite nicely (not shown in the videos).
My future plan is to modify my program to use motion tracking instead of finding the brightest pixel for tracking moving objects. This way, the camera panner will be able to track objects which are moving without…“candles”! :)
As always, I’d love to hear your comments and ideas… :)

hey man, can i download this? i have some ideas for a laser targeting robot.
Sure. If you've already made a floppy drive camera panner, then my program should work on your computer after making some adjustments. How can I send it to you?
I have made the camera panner. Could you email the the programs to dogsrcool2me@gmail.com? Thank you.
Your project is so cool. Can you email the programs to my email(dogsrcool2me@gmail.com)? Thank You so much.
sorry for the double post, I forgot to login.
Hi Ashish! All the best for your future projects!! Keep up the good work....
Cheers!

can i have a copy of the program to please??
Yonsje@hotmail.com
why not a video recorded by the webcam wile tracking ?
could you send me the program also ?
or just post it on the website ?
tataluguita@gmail.com
really nice :)
I'm interested in a project similiar to yours, but I can't find anywhere how you did the image processing from the webcam...
How did you get it to search for the brightest pixel and return this to your program? If you have any info, please email me:
cfinger **AT** gmail.com
Thanks a lot, and good work!
i have not made the floppy panner, but i am interested in modifying it to work with a servo setup.
btw, send it to miron721 a_t gmail do_t com
This Is GREAT the the parts are cheap as well PLEASE fwd me a copy of your tracking software. Thank YOU and Merry Christmas.

Graet Article
How did you track Infra red? did you use additional circuitry. Could you please e-mail the source code and any schematics to
ian@ifpg.co.uk
thank you
Great project I was wondering how you go about capturing data from the camera? I assume it's a USB webcam of come sort. Always curious how to do that in .NET. How do you process images? Do you use the directshownet libray over at sourceforge?
Thanks

Hi Ashish, I like your project very much, I tried to build one myself.
I managet to controll te floppy from the paralel port but, I can not make the program for kamera to trace pixels, like yours, when you enter in the room with a light, your kamera followed you.
Can you please send me the Source code to my email: besnikhaziri@hotmail.com or
besnikhaziri@yahoo.com
thanks so much
Ashish, try this article on CodeProject out for motion detection algorithms. It is quite spectacular!
http://www.codeproject.com/cs/media/Motion_Detection.asp
wow.. your project is so cool. i will try it. so can you send me your code? please send me (manhoi.hur@gmail.com)
Can you email the programs to my email a.botzung@wanadoo.fr
Thanks!
Nice work. Can you email me the source too? ncvanleeuwen _a_t_ gmail _do_t com
Thank you!!!
Hi.
great programs here could you email me a copy and the lasersketch program
sashah@hotmail.co.uk
thanks
nice piece of programming could you send me the source code to lazer guided camera panner please
my email is JERRY_41095@YAHOO.COM
Ashish,
Is it possible to get a copy of the source? I have a motion control project that is yearning for a webcam. Thanks in advance.

Hello, you´ve made an awsome program, I´m ordering some parts to do a similar setup like you right now, the problem is that I´m not a programmer, yet :P Could you please send the program.
rs232@mail.com
This is a very cool program. I have wanted to do that kind of thing for a long time. Can you send the program and source code to joshy_other_12_42@hotmail.com
I was also wondering if it were possible to make it track a green laser or at least a different color? If so could you help me with the software?
Thanks
hello
i m looking info /doc /source code for laser tracking
can you help me ???
thanks
can you send me your code please
redoxoder@gmail.com
thks
Iv been wanting to make a program like this for a while, and would like to see the source code some time.
hi great idea and program,can you send me the circuit and lasers you used,i have a few lasers at home and send me copy of your program if you can
i am using it for a AI robot design
jamericanfreddy@yahoo.com
nice work done.. very interested in integrating with my project.. kindly send me the source codes. siva_rocks@yahoo.com. thank you
Hi,
Could you please share your source code to me nguyenxh.net@gmail.com?
Thanks in advance.
Great guy! I always come to your blog to keep myself amused... and with interest on things you do but haven't tried any of it yet..maybe someday. Keep it going man, you've done a marvelous job!
How about letting the mouse select on the screen what the camera will track? More power!
Thanks for the nice post.
hey ashishd i want programme of laser guided camera panner plzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz ok in huryyyy
okz...
Hello
Hello, Ashish Derhgawen. I'm Fusan, Nice to meet you. my English writing was not good.
I like your project very much. Laser Guided Camera Panner, Object Tracking using Camera and Lasers.
How did you get it to search for the brightest pixel and return this to your program?
For Laser (it is LED, IR OR other). and you develop from C#, C++, VB or other?
