Cleanflight can used on Multirotor aircraft and fixed-wing aircraft, it supports a variety for shapes and motor counts, Not limited toQuadcopters, Hexacopters, Octocopters, tricopters and planes. Cleanflight is Open-source flight Controller software which is 32-bit version of the original 8-bit multiwii code.Cleanflight can be used in multi-rotor aircraft and fixed-wing aircraft, which supports a variety of shapes and motion counts, not limited tofour-axis aircraft, hexacopters, four-axis aircra

CompositionDrones are just a flying camera that doesn't directly elevate your work. On the contrary, because the height rises sharply, the difficulty of composition becomes bigger instead. The same scene, different aerial shooting height and angle, the film is also a big difference. We can choose different composition methods according to the shape chara

, so we use f[i][j] to indicate that the subtree with the root of I is down and the minimum cost of J points is not covered.Transfer:Consider how the DP array is transferred.Dp[i][j]It is equivalent to merging V into the current subtree.The F array can accumulate the answer directly, f[i][j]+=f[v][j-1].Finally combined with the greedy thought, for the F array, J bigger answer should be smaller, for the DP array, J Smaller answer should also be smaller, after finished take Max.Then pay attention

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.

So we want to be able to rise when the plane, not because the throttle suddenly increased suddenly and sharply, nor because the throttle accidentally pulled down too quickly caused the aircraft to fall quickly to the ground.Workaround:1.

The client is not able to issue a play request until a successful answer to the setup request has been received. The play request navigates the normal play time to the beginning of the specified range, and transmits the data stream until the end of the playback range. The play request may be piped (pipelined), which is placed in the queue (queued), and the server must put the play request into t

navigation. Navigation is the method of directing a person or device from the beginning of a specified route to the end point (cutler,2003). The application of navigation can be divided into non-civil (military) field and civil mass field. In the Non-civil field (military), mainly to guide the army and related equipment, ordnance, missiles, rockets and other operational deployment, in addition to the completion of related reconnaissance, surveillance
