- In this video I explain the Sentinel Tracking system and how it achieves it's accuracy using stereo vision, kalman filters, and interception calculations.
Make sure to watch the previous videos in this series for context.

Very well done video, your skills of 2D animation really complement explaining and help the viewers understand
Aw dude that means a lot considering they're super botched
Dale Sparrow yeah man even the long ass equation makes sense haha. I’m almost for sure going to go through with building my turret V2 (I already have one but it’s shitty) will probably be using lots of elements of your turret as it’s very well done. I’ll be sure to send you some content
Glad you are uploading video's again👍👍
Thank you for these videos, very inspiring and you have a great humor!
Love the videos, very well thought out and far more thought put into it than I've seen on any other videos. Great learning for my own project. Any chance you'll finish this series anytime soon?
The control systems video is very very close to being uploaded but due to the lockdown I can't get to that PC yet. Sorry for the delay, I wish I could do this full-time
I enjoyed your thoughts and insights. Let me know when you are in Joburg.
Sure! I think I saw your product once, the game pad controlled pole mounted turret right?
I saw your turret very interesting.
Can you tell me more about the control system?
I wonder how you model your system.
This is an awesome project!! Thanks for sharing what you are developing. Out of curiosity would the turret be 3D printable? The plate the motors bolt to being metal or a bracket to spread out the torque would probably be a good idea, but to cut down on cost printing the rest out of PETG or ASA would be super cool!
3D printing i applicable to many of the component apart from the motor and belts. I think that may be a good idea, but folded steel and aluminium may actually work out cheaper! You'll find all parts lasercut and bent probably will cost about $90
@@ThoughtinFlight Can't wait to purchase and build my own! Absolutely seller job on this project 👍
@@TheBitterBeardThanks :) I'm desperately trying to organise stuff in my life so I can develop this as a commercial maker product XD
Hello, I am a university student. Your video really helps us with our graduation project. I am going to make a graduation work by referring to your video. I have a question. Do you know the dimensions of your work when you try to create an external shape through a 3D printer?and i wonder your control system
Hi! I will hopefully add the control system soon. Busy with the final draft of my thesis so time is not friendly to me. What kind of shape are you trying to create? Your CAD program shows you your dimensions but when you print you'll have to account for filament size. It depends on the tolerances of your process.
Thank you very much for your reply. We need the appearance design features that hold the motor or gun. I'm in the middle of making the appearance design and I'm not sure how to start.Can you give me a file with 3D modeling?I know it's rude, but I'm so sorry. It's not for any other purpose but for university homework, but I can't graduate if I can't do this.
@@user-uz4kh5pd6f I wouldn't mind giving you some pointers but I currently don't have access to the files. I'll give you my contact details somehow soon
Dale Sparrow okay thank you i’ll be waiting

"Moerse Equation" ha-ha!
Interesting.
From my experience, the order of operations matters with high-speed signal processing. Why not as a first step try a Gaussian blur on the frame to filter out noise and find macro objects? Blur the image and the one-shot pixel noise will basically disappear. This will also "grow" your detected objects and normalize the area they consume before your binary filter.
Also, are you integrating the "background" images over constrained time?
Gausian blur is expensive to perform and can be achieved by just unfocusing the lense or getting a lower resolution camera which defeats the purpose. I automatically discard objects smaller than my noise range and larger than a certain size.
What I should have added to the video and forgot I did was I "eroded" the image and then "grew" the image which got rid of all the high frequency noise without loss of resolution.
On the background image integration, that can be done but the test runs were never long enough to justify activating it. If it had to sit in one environment with changing light over hours then totally worth it.
Please note this is a re-upload due to a muted section in the last video
Hi Dale, Let me know where I can get one of them?
@@juancarlosflores5421 Hi Juan, this was a prototype I made with my own money. Considering the interest, I think I might see what I can do to develop it commercially.
@@ThoughtinFlight Give me your contact may we can talk about it

do you have any more info or code examples on the stereo vision as i have been trying to get stereo vision distance measuments but i have not been getting verry good results
Hi Killnoobs, I wish I could post videos sooner then I'd love to help. I still need to post the last control system video then I'll do a QnA?
Good day sir, what the difference between your software and the project sentry gun's software that was made a few year ago?
I use stereo vision to determine the target's position, velocity and acceleration then I calculate the interception point with the equations of motion from the projectile and target.
How did you select the motor? I wonder why you used that motor.
In the first video I explained how I first calculated the rate of power input to accelerate the gun and then played that off with the amount of torque I could produce against the size of gearbox I needed. I also just looked at what similar types of mechanisms used such as hand drills.
It's nice physics remove your facial video screen and show the equations clearly on full screen
