Hello there, this is a very impressive work. could you please tell me how you managed to send velocity commands to the flight controller from the companion computer. I would like to know more about the Flight modes used. Thank you.

@yt3dkraft 11 ай бұрын

The drone's flight controller needs to be in guided mode. There are MAVLink commands, that allow movements with velocity vectors in the NED (north, east, down coordinate system relative to the drone body).

For anyone who is still wondering how to access the bottom camera. Update your drone to the latest firmware using the tello app, and make sure you set up the djitellopy repository in pycharm. After you do that using the following code you should be able to get a live feed of bottom camera footage: from djitellopy import Tello import cv2 tello = Tello() tello.connect() print(tello.get_battery()) tello.streamoff() tello.streamon() tello.send_command_with_return("downvision 1") while True: img = tello.get_frame_read().frame img = cv2.resize(img,(648,488)) cv2.imshow("Image", img) if cv2.waitKey(5) & 0xFF == ord('q'): tello.streamoff() break

Quick question here, do you know if it is possible to install ROS, ROS2 or gazebo on a raspberry? I've been trying to do that for a while, but haven't succeeded

@yt3dkraft Жыл бұрын

You can build ROS Noetic on Raspberry OS Buster 32 Bit (not supported for Bullseye) but i would not recommend to go that way as it will mean that also almost any ROS package and there dependencies also must be built from scratch. I would recommend to install Ubuntu MATE (20.04 for ROS Noetic or 22.04 for ROS2) 64 bit on RPi (4B or CM4). There are also ways to get the Pi Camera v2 running with V4L2 on MATE. Then you can install ROS packages using apt.

Technically you got this wrong: Croma subsampling does not apply to the same principle as if you could easily pixel-bin it to get back the data from sensor. It was not encoded in a first place, hence it still looks "shallow" and kind of bleak compared even to 2k cdng footage from arri or even 5dm3 mlraw encoding. Still it's a lot better in many ways, but still bot a 4.4.4

@yt3dkraft 3 жыл бұрын

Mathematically, my description is correct. Practically, you may still see a _slight_ difference between footage that was recorded with a sensor with the same number of red, green and blue pixels (like a foveon sensor) in native resolution, but the result of downsampled 4:2:0 footage can be closer to "pure" 4:4:4 than to anything else. Your comment regarding footage from Arri or 5D MK3 seems to address advantages of raw data compared to encoded data. But this has no influence on the chroma subsampling. Even if you have 14 or 16 bit raw, it is still 4:2:0 when it comes from a bayer sensor and is not downsampled - even if the format for storing the data would allow to save it as 4:4:4. Your recording format can not regain information that is already lost at the sensor.

@danieIlondon 2 жыл бұрын

The way this works is quite technical but it essentially amounts to using the extra pixels present in the 8k files to rebuild the lost colour information. Neighbouring pixels are summed to create a super pixel with a greater bit depth and better sampling. It requires a lot of processing power and a finishing codec good enough to store the extra colour data.
