I need someone to help me modify a Demo(FPGA: Xilinx Basys3 Language:Verilog) which is a object tracking system based on a pan-tilt.
I think the modification won't be a big task, because the imaging processing algorithm works well, the need of modification is in controling two servos, especilly in getting back servos' position.
The original demo get servos' position by using four wires servo(PWM Vcc GND feedback). But I cannot find this kind of servo in the online shops.
Actually, I have some plans.
a. writing an algorithm like this blog, [login to view URL]
b. using some sensors like Accelerometer Magnetometer Gyroscope. But I think there might be several problems.
For accelerometer and gyroscope. Integral will increase error during continuous operation?
For magnetometer. Electromagnetic effect induced by servos and CMOS camera might cause bad data?
Or, any other sensors I haven't mentioned will work better?
Therefore, I think we need some chat to find a solution before start working.
