DIYA UAV Vision tracking system based on Raspberry Pi and PythonThe drone's image is stored and transmitted to the Earth station in real time, almost standard. If you want a bit more advanced-how do you do it directly on the drone and automate the shooting process? In fact, the visual tracking has been in some high-end consumer-class UAV has the application, but play ready-made never do their own hands;). S

DIYA UAV Vision tracking system based on Raspberry Pi and PythonThe drone's image is stored and transmitted to the ground station in real time, which is almost standard. Suppose you want something advanced--to process the captured image directly on the drone and implement your own active control.

Use the command line to set Raspberry Pi's Wi-Fi network If you have not logged on to the Common graphic user interface, This method is suitable for setting Raspberry Pi's wifi. Especially when you do not have a screen or wired network, you only use the serial control line. In addition, this method does not require additional software, and everything is included
