Faster, stronger, Smarter, and Leerer use these four words to describe the new Elf Phantom 4 that has just appeared in Dajiang. As the major product line of Dajiang’s mass-market consumer market, the Elves’ Phantom drone series has evolved into three generations, and both the product form and consumer cognition have achieved certain results. Under the international trend of intelligent drones, DJI, whose attitude has been relatively conservative, has not been calm. Computer vision has been introduced to increase the three functions of "obstacle perception," "smart follow," and "pointing flight." The biggest update brought by the new Elf4, or the part that attracts the most consumers, is to increase the obstacle avoidance function. We know that the flight control system is the key to scoring a drone, and the obstacle avoidance function occupies a large part. This is the first time that Dajiang Wizard 4 has introduced "computer vision" technology into its own family of products. DJI called this system the "Obstacle Sensing System", which uses two front cameras and is located near the landing gear. When the front object is found, the distance between the object and itself is evaluated in real time, so that the sprite 4 automatically bypasses the obstacle to fly; if it can not find an alternative route, it will keep the original trajectory, or hover in the air to continue the operation. Of course, this system will only work if you control the Wizard 4 to fly forward. If you fly backwards, you can only rely on the original method - to judge "road conditions" with your eyes. The effect of video obstacle avoidance in the live demonstration is not bad, but there is no exact third-party evaluation data to illustrate the ease of use and accuracy of this system. It is compared with the YUNEEC drone with the real sense technology exhibited by Intel at the beginning of the CES. In comparison, the computer vision of which product is better is still unable to draw conclusions. At the press conference, Wang Da, founder of Dajiang, was very confident in this technology. He said: "The Elf 4 is my most satisfying product so far. Welcome to the era of machine vision." For a long period of time in China, when the same level of consumer-class drone products on the market were adding "auto follow" and "pointing flight" functions, Da Jiang did not follow up, and Elf 4 this product will make up for the previous The regret left behind. Elf 4 is equipped with a dedicated mobile phone APP to complete the flight, shooting, sharing and social functions. The APP can be used to receive live pictures taken from the camera. This means that you can make it follow a moving object in the field of view of any drone, such as a bicycle, car, or animal, and lock it in the center of the picture. It is not necessary to use ground-based GPS positioning equipment (most quadcopters require). Similarly, there is a smart sensor "TapFly" for camera positioning. As the name suggests, anywhere in the video stream clicked, Wizard 4 can fly in the direction you choose. When an obstacle is perceived, it automatically hover or bypass the obstacle according to the environment. Battery technology has long been a major pain point for drones, and Dajiang did not solve it this time, but it has seen a slight improvement. Compared with the previous generation Genie 3, Genie 4 can last for 28 minutes on a single charge, increasing the time by about 5 minutes. The official data is increased by 25%. Here is a comparison of the parameters of a Dajiang Wizard 4 and Wizard 3 Professional: The new generation of Dajiang Elf 4 looks like an outstanding collector of current technologies, including computer vision and smart sensors. In fact, it is not a high-tech black technology, but their addition will undoubtedly make this product even more plump. The consumer market is more competitive. Dajiang Wizard 4's foreign price is 1399 US dollars, the retail price in mainland China was set at 8999 yuan, although it was first released in New York, the United States, but its official website in China has also begun the Elf 4's simultaneous booking, March 15th Since the beginning of delivery.
