i would like to build a follow me type system for my drone
based on object recognition and distance measurement
i have succesfully deployed and tested the opencv face recognition on my Raspberry 4 , but since jetson and Rb 4 are quite big for a drone i am looking for something smaller with a width 30mm to fit on to the drone
Microcontroller
Size (mm)
Price (USD)
ESP32
25 x 18
$5 - $10
OpenMV Cam H7 Plus
45 x 36
$65 - $85
Arduino Portenta H7
66 x 25
$99
Arduino Nano 33 BLE
45 x 18
$20 - $30
Kendryte K210 (Sipeed)
53 x 25
$20 - $35
STM32F4 (Nucleo-64)
70 x 32
$10 - $20
Raspberry Pi Pico
51 x 21
$4
what option the best option considering size and performace for my project?
if you have to ask, you don’t have the necessary background/experience to approach such a project. sounds harsh, but you have got to face reality.
you are a hobbyist. that is why you even think to include generic underpowered devices.
what you’re asking requires deep neural networks. DNNs require serious computing power.
there are dedicated AI accelerator chips that would be required in such an application.
some of those, like the K210, might have the power to do what you need. I don’t know if the K210 is even still supported. that time was in 2018-2020.
companies employ educated and experienced experts to develop such solutions. they engineer solutions that work at the limit of feasibility. a company might be able to make it work. you can forget about that.
if your drone is too small to carry a jetson, it’s too small to do anything useful.
just buy a DJI with the features you want. expect to pay for it. because that’s the cost of such features.
thank you for your answer.
it’s a little unclear what got you so excited.
as i already wrote that i have successfully launched the portotype on RB 4 and Jetson Nano , everything works, detects , calculates speed and distance.
all steps on drone are done its autonomosly flying using px4 flight controller and ardupilot mission planner
i’m just considering options for alternative microcontrollers to reduce weight to solve my tasks that’s all
PS:
I always liked depressive and pessimistic people, they reminded me of my younger brother)
it always motivated me, and moved me.
I will do everything out of spite and send a link to how it works)
