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. In fact, visual tracking has been in some high-end consumer-class UAV has the application, just play out of the

Use the raspi-config tool to configure Raspberry Pi A) view IP addresses Under normal circumstances, Raspberry Pi can be started, but he still does not know his IP address, and he cannot access the system through SSH. If he will use a router to view the IP address, it is not a pr

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
