Object Tracking using Camera and Lasers
Hey folks! Here's a little something I built about a month ago, but couldn't get enough time from college to write about it. Well, it's an object tracking camera panner which tracks any object moving in close range. Unlike my previous method for object tracking, this technique will track almost any moving object, irrespective of its color, using two lasers for edge detection. Depending on which laser is focused on the object, the computer decides which direction to drive. I came up with this idea after watching a video on SoR (Society of Robots) of a sumo robot, called Stampy. Stampy uses a single IR rangefinder for edge detection. Watch the video below:
I used lasers instead of IR rangefinders. My initial plan was to use a single laser..but then it occurred to me that I would have to shake the laser left/right continuously for tracking the trailing edge of an object. So, I decided to go with two lasers instead of one. :)
Well, I guess I've finally put my computer controlled stepper motor to some use. I might be using this object tracking technique in my future projects as it's working very nicely. If you're interested in controlling stepper motors with your computer, read my new article on Coding4Fun. Enjoy! :)

This is a pretty good idea. You must have thought of it yourself or must have been inspired from somewhere, but whatever it is, its good.
Here is something much more advance but the same idea, maybe useful to you for improvements.
the laser tracker was neat.
i love electronics/pc interfacing too.
where are you located ? - if you are in the new delhi area,i'd like to synch up with you.

thought I'd chime in, I like the work, well done. Just an idea to help conserve power, you could still only use one laser, and just use a beam spliter in order to get 2 dots. A piece of plexi-glass would suffice, unless you had an old CD/DVD drive you could salvage, some have small cubic beam splitters inside.
That's a really good idea. cheers
This is John from societyofrobots.com. I see my Stampy has inspired you =)
Good job! I was already a fan of your webcam + laser idea already =)
I'm glad you liked the idea. :)
Your website is the best. :D
hey ashish, what are you using BasicStamp or PIc, and if your using PIC, which version are you using.
Hey, I have a commercial application for this. If you want to possibly make some money with this idea... let me know.
Nice project! I am very interesting with your work... If you dont mind, i'dlike to know what programming language do you use for this project.. Thanks!
@Lemoj: I used C# :)
Pretty nifty app that you have made..I like it a lot.
I am trying something similar for a project,and I actually do tyriangluation using recognition of a laser spot using a camera,
I need some info from your side,Do you mind sharing?
Let me know of your comments
Ur projects r awsome.Keep it up.
I'm very much interested in Robotics,Obstacle sensing,motion detection etc.
But i don't know where to start.Perhaps U can give me some guidelines or staarting point regarding Mechanical part as well as programming part.
Im a mechanical engineer student of BUET bangladesh. My eamil add. is email@example.com
Outstanding brilliance Ashish!
Can u pls mail me the source code or at-least an application code for this project. My email address is : firstname.lastname@example.org
Why don't you couple your obstacle detecting RC car with this one to form an intelligent object tracking robot...
i just want to ask you if you can email me the code of this?can you?
again, my email is email@example.com
i am looking forward to your reply.
Very neat job on this project. I'm interested in robotics but I'm not yet oriented in the programming part. Can I have a copy of the compilation code in this project just for my study? Please send it to firstname.lastname@example.org Thanks!
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?
Can you please send me the Source code to my email: email@example.com
thanks so much
hi buddy.i m rocky from gujarat.i likes ur project so much.i want to make this project.can u plz give me the discription & circuit diagrams of it? i m having to give my project after some months.plz give me all details abt it. & also tell me the place from where i can get the components of it..pls help me as fast as u can..
u r really geinus, i love to do projects in automation, now i am intrested in doing projects in microcontrollers, can u assist me how to begin and how can i learn microcontroler programming,how can i learn to do project in microcontroller.
i am planning to do one project on counting gas cylinders using any tech or image processing, please guide me how to do and start with.
OIL & GAS
pls send me the idea of project & how to begin thx alot...
my e-mail: firstname.lastname@example.org
great idea with greater implementation. i am mukesh harsh from bikaner, rajasthan. can use pair of IR instead of laser so that the dots can be invisible on object ?
hey Ashish, I'm a undergraduate student from korea.
I'm doing a project about stereo vision and i'm going to track and move my camera using two servo motors..
Then I saw your post! Is it okay if I ask you for the source files? It would be very helpful, please..
I'm not sure if you would see this comment very soon. But i'll be waiting for your reply.
This is pretty good idea
i'm planning on working similiar project this semester but some concepts required OpenCV coding
yours is simple idea
could you mail me some concepts and references at
Great stuff thanks! This can be very useful for <a href="http://www.intechopen.com/books/show/title/object-tracking”>tracking</a> malicious users!!
your project is very good
please send report, coding etc… on my mail
pls send me thats helpful in my project
your project is very good
please send object tracking robot report, coding etc… on my mail
pls send me thats helpful in my project
please send the source code to my email
Could you please send comptiled version to email@example.com ?
This is a great idea and such a great implementation.I like your project.Your website was really good.

hello sir i am a student in computer science Engg and i have to make a project on software + hardware so i found your "object tracking using camera and lasers " project but i dont have any idea about embedded systems so can u help on what shall b the requirements of the project and how to design the project?
Nice article, thanks for the information. It's very complete information. I will bookmark for next reference

It's really interesting project.
can u plz send me report , coding of dis project on firstname.lastname@example.org ?
Could you possibly share with me the code you used for tracking?
