1. IntroductionIt is believed that many of the friends who play open source drones have a drone on their hands, rather than just staying in theoretical learning and program learning. Flying their own assembled UAV is fun, then this article introduces the installation of the essential ground station software Qgroundcontrol to play UAV, of course, can also use Mission Planner ground station. QGC and both can

(Li-Poon) proof: Each real matrix can be written as a linear combination of $4 $ real positive matrix, that is, if $ A $ is a real matrix, the real positive matrix $ q_ I $ and the real number $ r_ I $, $ I = 1, 2, 4 $, make $ \ Bex a = r_1q_1 + r_2q_2 + r_3q_3 + r_4q_4. \ EEx $ Proof: (1 ). first, it is proved that the spectral norm of $ A $ is the maximum singular value of $ A $. in fact, $ \ beex \ Bea \ Sen {A} _ \ infty ^ 2 =\ Max _ {\

Version:pixhawkIde:eclipse Juno (Windows)Iv. Basic KnowledgeIn the early stage of multi-rotor UAV, it is necessary to understand its aerodynamic layout and complex dynamic model, then the attitude calculation and controller design. In order to realize the attitude estimation of the precision four-rotor aircraft, the first is to understand the reasons for the existence of the data and the errors, then the various mathematical operations (all based on

The development of simulators in other fields is also flourishing: in the field of home environment simulation, MIT and the University of Toronto jointly developed a feature-rich Virturalhome Simulator, and MIT has developed the flight Goggles simulator in the field of UAV simulation training.7.

Life is not easy, programming depressed, rather than "man-made" points of interest, so that the day has a more playful feeling.This article refers to a number of project recommendations, sorting out some of the programming language in the individual think more interesting, but also relatively practical open source projects, each language column is not much, interested in the free can try.First, Go1, GobotGobot is a robot, UAV, and IoT framework that p

ObjectiveIn the field of computer vision CV, visual tracking is one of the important sub-problems. From my point of view, visual tracking is used on robots, on mobile devices, so why not put some tracking algorithms on the iphone to see the actual tracking effect. This is the most realistic comparison, the use of some video is not practical, and the key is not very good comparison of real-time. For mobile devices, real-time is the most important thing. The reason for the emergence of tracking pr

Title Link: http://nanti.jisuanke.com/t/440 Assuming that the final answer is known, a point logarithm formula with a point x as the root can be listed, where CX represents the number of subtree drones that x is the root, and Xi is the direct child node of x: According to the formula you can see the points: (1). If a point satisfies the condition, it is only related to the distribution of the subtree UAV with the root of the point. (2). According to

In an age when artificial intelligence is maturing, there is a lot of data to be processed. At the same time, we can see the python figure in the data processing of AI, VR and unmanned vehicle, UAV and smart home, which will promote the future demand of Python in the enterprise.As for the reasons for the popularity of Python, in my opinion, it is the following two points:1.Python is the first language of artificial intelligence (AI) and data analysis.
