Hi so basically I want to build a micro Quadcopter and transmit the Video feed to my computer.
My question is: Is it possible to transmit the Video Feed that OpenCV on my computer can command the quadcopter wirelessly.
So that I dont have to put a raspberry on my quadcopter (It actually couldnt lift it).
Or if I understand it wrong I’m sorry.

Yes it is possible , you can check on these experiments:
I would like to show my work (in progress) on a simple system capable to realize indoor autonomous flight.
The system is based on a quadcopter with a camera that stream video (and telemetry) to a desktop PC and receive pose estimation message and command from the same PC.
The camera is downward looking and on the floor there is an Aruco Boards like this:
[ppp]
The pose estimation is calculated by aruco_gridboard ROS package on the PC and the relevant messages are sent back to the quadcopte…
Hi all,
I am trying to autonomously control my Skyviper drone in a map consisting numerous Aruco markers on a plane. I am able to localize my drone by using the aruco detection and pose estimation libraries that OpenCV provides. I have written a ros node that publishes /mavros/vision_position/pose which contains the pose of the drone in NED coordinate system. I have whitelisted vision* and local* plugins in the apm_pluginlist.
Then I switch on my drone and connect my PC to it via WiFi. Next, I…

He mounted the Raspberry Pi 0 on the quadcopter what I wanted to avoid.

The RPI zero is used to send video over wifi to the remote OpenCV, please read throughfully

Yeah but the RPi 0 is mounted on the quadcopter.

Nope Mavlink is telemetry

yeah but I can control the Quad over Mavlink with MissionPlanner…so it should be possible to send commands to the Quadcopter

Yes but not video , it has to be wifi or analog

Hmm then I didn’t properly understand the OSD with the Telemetry

OSD isn’t live video, it’s a video overlay of data.

OSD is a microcontroler (AVR , STM or other) that reads MavLink Messages and output to a character generator that is mixing (overlay video) an analog signal from an onboard camera and transmit the resulting over RF using analog transmitter generally on 5,8 Ghz
