In 2015, with the explosive growth of drones, domestic and foreign drone companies have launched a full-scale competition, and various new technologies have emerged one after another. The competition in the market is arguing or technical accumulation and competition. Then, the question is coming. What innovations and practices have the drone companies made in technology development this year? Which technologies can leave a mark on the drone technology list?
ç…çŠ top of the list - automatic obstacle avoidance
UAVs have exploded, and various security issues have been reported frequently. UAV security issues cannot be underestimated. At present, consumer-grade and commercial-grade UAV manufacturers have begun to use "obstacle avoidance systems" as product focus. There are three main types of mainstream electric multi-rotor UAV obstacle avoidance systems, namely ultrasonic, TOF, and relatively more complex, multi-range methods and visual image processing.
In early June, Dajiang launched the intelligent obstacle avoidance system "Guidance", which can be used to develop the "latitude and longitude" series (Matrice 100) of the drone platform, using a composite obstacle avoidance system. Zero at the Innovator Summit in July, the first demonstration of the automatic obstacle avoidance function of the drone, using the UF TOF obstacle avoidance system.
Reasons for the list: UAVs, especially consumer-grade UAVs, are growing rapidly, all kinds of whites are entering, and security issues are frequent. How to avoid obstacles to ensure the safety of others and their own is especially important, flying is valuable, and the price of life is higher! ! However, as far as the current obstacle avoidance method is concerned, there will be different ways of interference and short effective distance. How can we truly avoid obstacles in all directions, and visual inspection is a journey. . .

ç…çŠ çœ¼ - GPS follow
The follow-up function of the drone is a point of concern for professional enthusiasts. At present, the main solution is GPS follow-up: the aircraft achieves point-to-point tracking by locking the GPS module of the target or the GPS signal sent by the carried device.
The 3DR drone IRIS+ supports the "Follow Me" feature, which tracks any Android device with GPS capabilities, and the Sprite 3 also supports hotspot followers. Some flight control ground stations also support following flight functions, such as the Dajiang NAZA-M V2, the zero-degree X4 V2, and the polar-wing P2 PRO, all of which are automatically followed by GPS.
Reasons for the list: This technology has been overcome by many companies, ranking in the second place, completely out of the feelings of enthusiasts, but also really cool, think about a drone, it is sour!

ç…çŠ æŽ¢ 探 —— - indoor visual positioning
The emergence of indoor visual positioning systems is definitely the favorite UAV technology highlight for players who like indoor flight and shooting.
Dajiang has used the indoor positioning system in both Wu 1 and Elf 3. This virtual positioning technology enables the aircraft to accurately position and fly indoors. As one of the biggest selling points of Elf 3, with the popularity of Elf 3, indoor visual positioning has won great market praise. However, the DJI indoor positioning system is only used on its own machine and does not provide matching.
After DJI, Polar Wing also successfully launched the indoor visual positioning system. It is the second enterprise in China to apply optical flow and ultrasonic sensors to drones. It was exhibited in the Shanghai Model Exhibition in August. The polar wing highly integrates the optical flow and ultrasonic sensor positioning technology into a single module (optical flow sonar module), combined with the polar wing flight control indoor flight, enabling the drone to achieve high-precision indoor positioning and smooth flight, effective The height is even more than 2m beyond the Dajiang Elf. However, unlike Dajiang, this product is currently mainly sold by manufacturers and is not retail.
Reasons for the list: Effectively solve the problem of indoor inability to accurately hover and smooth flight. This is definitely a great benefit for some enthusiasts who are not interested in flying indoors or various indoor aerial photographers. The most important thing is that if the outdoor GPS signal is poor, the positioning function can also be achieved.

ç…çŠæ¦œNO.4——Building a mobile terminal operating platform
Combining the product with the mobile side, simplifying the control and providing a differentiated and innovative handling experience is a major trend in the development of drones this year. Although Yihang completely uses the mobile device APP to simplify the drone control mode, and realize the mobile device APP control and intelligent flight, in fact, it is still the mobile ground station control. However, the new product is still very big, and the Avatar model looks very cool and does a good job.
As early as 3 years ago, French drone company Parrot has realized the operation of mobile phones. Somatosensory control and virtual joysticks are undoubtedly revealed on Bebop. In this way, Yihang is not the first to eat crabs, but he does Let more people see the possibility of being completely out of the remote control.
Reasons for the list: Watching is high, but can not deny its trend development, simple, lightweight, easy to operate is the trend of consumer-grade UAV development in the future.

FTop FIVE - Water Operation
Lily drones burst red all night, waterproof, throwing and follow-up are the three concepts of Lily drones. Waterproof is a function that no other manufacturer can achieve. For users who like selfie and water sports. Lily is very attractive.
Lily uses GPS follow-up, that is, there is a GPS module on the aircraft and on the controller's hand, all of which can obtain GPS data. The algorithm of the flight control write allows the aircraft to follow the "remote control" on the operator's hand. However, this summary mode of the airline and 3DR flight control system can be achieved, so lily does not have obvious advantages, perhaps it can be said that the essence is greater than Shantou.
Reason for the list: Fun to install drones, may be too serious, may be too fashionable, or just like Lily. Love to play, just like to force! Perhaps it can be said that it is a follow me with a waterproof flag.
