Is UAV easy to use? Come to Sina public test to apply for the latest Royal mavic air 2 for free
Remember this time in 2018, the new mavic air came out. At the New York conference, everyone was shocked when the host pulled the folding drone out of his jacket pocket. Once again, Dajiang has refreshed the volume of the folding UAV, which is almost the same size as the iPhone X and can be folded, and only has the weight of a bottle of mineral water, which can be easily put into the pocket.
Great Xinjiang mavic air 2 is coming!
Although the volume is reduced, but the performance is not reduced. The 21 minute, 4-kilometer picture transmission and 1 / 2.3-inch CMOS are more than enough for travel photography.
In the past two years, Dajiang has successively launched Dajiang Yu2 series, which is combined with hassu, and the mini UAV yuvic mini, which can fly indoors. However, the mavic air has not been updated.
Two years later, we finally waited for an upgrade of mavic air – mavic air 2. After two years of dormancy, what surprises will the new mavic air 2 bring us? Before the launch of mavic air 2, Sina digital has already got the UAV, and will share the flight experience for a few days.
Bigger and heavier fuselage
At the first sight, it was very surprised to see mavic air 2. Although it is only the second generation product, the whole design style has changed a lot. It’s totally transferring to Yu series. Mavic air R2 continues the folding structure of Yu series, but its volume and weight are increased compared with the previous generation product.
Much larger than the previous generation (mavic air 2 on the left)
First of all, it’s obvious that mavic air 2 is larger than mavic air. After querying the official parameters, we know that mavic air 2 is 12mm longer and nearly 28mm wider than the previous generation. The weight of mavic air 2 is 570g, 140g heavier than mavic air, and the volume after deployment is significantly larger than mavic air.
The weight also increased significantly
More obvious after deployment
You may want to ask why mavic air, which should be smaller and smaller, is coming in the opposite direction? But in fact, it’s redundant that there’s no 1g weight on the mavic air 2. Let’s take a look at the hardware parameters of the mavic air 2, and you will know that the weight and volume improvement is worth it.
Compare mavic air with mavic Pro
Dajiang mavic air 2 is equipped with a 1 / 2-inch CMOS sensor, which can take 48 million pixel photos, support recording 4K / 60fps video and 8K mobile delay video; there is a 34 minute endurance time and a maximum of 10km high-definition digital image transmission distance; the P-speed is increased to 43km / h, and the maximum flight speed under the sports mode is 19m / s. The intelligent flight ability has also increased significantly. Compared with the mavic air, it has definitely improved in quality. Its weight is not wasted, and it is completely approaching the Yu2 series.
But it can be put into the backpack gracefully
Although the body is heavier and larger, the portability of the mavic air 2 has not been greatly affected. After folding, the UAV can still be easily packed into a backpack and taken away. It’s just the official standard bag of a generation. The mavic air 2 can’t fit in
This time, the mute paddle is also equipped with mavic air 2 as standard
Dajiang has developed a new silent paddle. This time, the whole series is also equipped with mavic air 2 as standard, which can improve flight performance and enhance noise control. In the same way, the folding design is also adopted for the blades, which can also increase their damage resistance to a certain extent.
In addition, one of the great advantages of UAV folding design is that after each flight, only the UAV arms need to be folded to be carried, and the blades need not be removed; when flying again, only the arms need to be expanded, and the propeller will also be expanded to the flight state under the action of inertia after the motor is started, so that the players can complete the flight preparation in a short time 。 If you look closely, you can see that the tail tip of the mavic air 2 blade has been bent to help reduce the noise.
There are binocular vision sensors at the front and back of the fuselage
Mavic air 2 is equipped with binocular vision sensors in the front and back directions. It is equipped with apas3.0 advanced flight assistance system, which is similar to the vehicle assisted driving system. It can identify obstacles in front of it in the front and back flight, and plan obstacle avoidance paths independently to ensure a consistent shooting experience.
Lower part of fuselage
The lower part of the fuselage is equipped with a downward looking binocular vision sensor and an infrared distance sensor, which can hover accurately within a height range of 50m. The LED fill light enables the UAV to rely on the binocular vision sensor for positioning at night. Unfortunately, there are no visual sensors on the left and right sides. So we need to be careful in the flight process. After all, obstacle avoidance is not omnipotent.
The battery moved to the top of the fuselage
With the increase of the endurance, the battery of mavic air 2 also moves to the top of the fuselage, which is heavier, and there will be a green circle when charging.
Larger battery, but longer endurance (right: macic air 2 battery)
The mavic air 2 still has a foldable remote control and needs to be used with a smartphone. But this time, the remote control has a new design, which is a circle larger than the traditional Yu series remote control, and the clamping structure has also changed, which has been changed in the above.
Now full screen mobile phones break out, the traditional way of holding under the remote control is easy to block the screen. The new clamping structure can better adapt to the full screen mobile phone, with better control experience, and can also charge the mobile phone.
The newly designed remote control is more suitable for full screen mobile phones
Most importantly, the newly designed remote control has a 240 minute endurance, so you don’t need to worry about the power loss of the remote control when you fly out. In fact, the batteries of both UAVs are dead, and the remote control only uses one grid of electricity.
More intelligent shooting
Next let’s take a look at the improvement of the performance of the mavic 2 in Xinjiang. At the beginning of the birth of the consumer drone, no one had too high requirements for its photography level. If this new thing can fly and shoot, people will be very satisfied. With the development of products, users are increasingly demanding more of their photo taking standards, just like mobile phones – now the mobile phone photo taking function has become the biggest selling point of manufacturers.
A camera with a larger background
Equipped with a 1 / 2-inch CMOS sensor, the mavic air 2 can take 48 megapixel photos, 4K / 60fps video and 8K mobile delay video (the function will be turned on when it is released). Compared with the 1 / 2.3-inch, 12 megapixel CMOS sensor of the first generation, the improvement is very obvious.
Interestingly, mavic air 2 adds intelligent photo taking mode, including scene recognition, pure night shot and HD three technologies, mainly intelligent recognition of aerial photo scenes and algorithm optimization for different scenes.
This is very similar to the AI photographing of smart phones. However, from the actual experience, the smart photo mode is far less intelligent than that of smart phones, and more simple optimization for large scenes. But for the novice drone, this function is very practical, at least it won’t let you take bad photos.
Sample photos taken with sufficient light
However, the improvement of the image quality of mavic air 2 is real. When there is enough light in the daytime, you can see that high pixels increase the expressiveness of details, the blue sky and white clouds are clearly layered, and the sharpness and resolution of the picture are good.
Zoom in on 48 megapixel photos
When you zoom in on the 48 megapixel photo, you can see that the details of the vehicle on the high-speed display are quite clear. Don’t worry about the jitter that often occurs in mobile phone shooting. But if you’re looking for contrast and color, it might take a bit later.
Dark light shooting
Dark light scene is the best place to show the advantage of big background. From the perspective of the sample, due to the large-scale CMOS, the noise control of the night sample is significantly improved compared with the previous generation, and the purity is better. And in some dark areas of the details of the performance also improved significantly.
There are many intelligent and interesting shooting technologies for Dajiang UAV, among which APAs (advanced auxiliary flight system) is more important. It is similar to the automatic driving technology in the field of automobile, which not only makes the flight more interesting, but also more safe.
This time on mavic air 2, APAs also upgraded to 3.0, using a new generation of map technology and global path planning algorithm. Compared with the previous generation of products, the obstacle avoidance performance and the ability of path planning have been greatly improved.
In autonomous flight, when encountering obvious obstacles such as big trees or tall buildings, you can easily avoid them.
The more complex scenes are still a little confused
But in some complex scenes, such as in the grove, when there are many leaves and branches, the mavic air 2 will also be a little confused
Intelligent follow and interest point surround are always popular functions of Dajiang UAV. Their biggest feature is simple operation, and novice can also take a big picture.
Intelligent follow shooting car
This time, intelligent follow has been upgraded to 3.0. The biggest improvement is the ability to recognize the target again after the target is occluded, which can predict the target position more quickly and accurately, and maintain continuous follow.
Through the actual test, we can see that we turn on the intelligent follow to shoot the car, and encounter the shelter of the traffic sign during the process. Mavic air 2 not only flexibly avoids the obstacles, but also quickly re locks the target.
More complex environment photographer
The same is true for the photographer. As for the man running in the woods, the scene is too complex and the target is lost soon. However, mavic air 2 has been locking the target’s general position, and the target will be locked again as soon as it appears.
Point of interest around shooting mobile cars
The point of interest orbit is to orbit the target, and the camera is always shooting towards the target. Compared with interest point surround 2.0, interest point surround 3.0 can identify mobile subjects, including pedestrians, cars, boats, etc.
From the actual experience, when the speed of the locked mobile car is relatively slow, the interest point surround can always be shot around the car. When the speed is slightly faster, the target will be lost when encountering occlusion. This function is more suitable for shooting slow moving objects.
The delay shooting function added to Yu2 series for the first time also has a new playing method on mavic air 2. Mavic air 2 can shoot 4K and 8K resolution mobile delay videos, but the 8K resolution mobile delay video function can only be opened when the retail version is launched, supporting free and track delay functions.
Shooting free delay
Shooting a period of free delay takes about more than 4 minutes, and the overall experience is very smooth. The camera takes 125 consecutive photos to synthesize a delay video. This simple direct output scheme is not only convenient, but also allows UAV video creation to have more forms of expression.
The ability to add the delay shooting function to the UAV really reflects the technical strength of Dajiang. Because to introduce this function to the UAV with shorter dead time, there are very high requirements for the UAV’s flight attitude stability, endurance time and the aircraft’s calculation ability. It’s not as simple as the delay function on other video devices.
Image transmission is a very important aspect of aerial UAV, and stable image transmission is the most basic guarantee of aerial photography. Dajiang launched lightbridge technology in 2014, which can transfer pictures as far as 5km from UAV to mobile screen in real time. In 2016, Dajiang also brought ocusync HD digital image transmission. The maximum remote control image transmission distance can reach 7km, and 1080p images can be previewed in real time.
Support full HD image transmission
Mavic air 2 has also been upgraded to ocusync 2.0 HD image transmission technology. The farthest image transmission distance has been extended to 10km. It supports 2.4ghz/5.8ghz automatic switching and can directly cache Full HD video in flight. The new 5.8GHz channel can keep the stability of the image transmission signal in the busy environment.
Occasional loss of connection
Of course, the 10K is only a theoretical figure. In actual flight, it is likely that there will be no return. From the actual experience, it’s about 3km. The picture transmission has begun to show the video card, and the aircraft will lose contact intermittently. As for the direct cache of Full HD video in flight, it’s still a word, “card”. It’s better to go back to the local cache video honestly.
Substantial increase in endurance
The UAV’s endurance is too short has always been a difficult problem to overcome. This time, mavic air 2 refreshed this number to 34 minutes, far more than the 21 minutes of the previous generation products, even longer than the Yu2 series and mavic pro, which can be said to be the “most lasting” UAV.
On the day of our test flight, it happened that the wind in Beijing was quite strong, the flight height was about 80 meters, and the acceleration process was very smooth. In the actual test, hovering, flying, video recording and photographing are carried out alternately; after 22 minutes, 20% of the electricity is left to start to return automatically, so it is estimated that there should be no problem in normal use for 30 minutes.
Of course, you don’t have to worry about the last few minutes. It’s better to bring an extra battery than anything else.
Conclusion: better shooting, more stable playing
It took two years to update the mavic air, and Dajiang really felt like “squeezing toothpaste”. However, good food is not afraid of late, Mavic Air 2 upgrade is still very awesome. With stronger hardware performance and more intelligent shooting, mavic air 2 can match the flagship Yu2 series. Of course, this is at the expense of a certain degree of portability.
So far, the route of Dajiang UAV is very clear. If you’re a beginner and just curious about drones, the first generation of mavic air and mavic Mini are good choices.
If there is a certain flight basis and shooting requirements, we can focus on the main characters of today’s mavic air 2, mavic pro and even the zoom version of Yu2 series. The professional version of Yu2 series is the choice of professional users.
