Dà-Jiāng Innovations (doing business as DJI) is a Chinese technology company headquartered in Shenzhen, Guangdong with manufacturing facilities throughout the world. It is known as a manufacturer of unmanned aerial vehicles (UAV), commonly known as drones, for aerial photography and videography. DJI also design and manufacture camera gimbals, flight platforms, cameras, propulsion systems, camera stabilizers, and flight control systems.

DJI is the world's leader in commercial and civilian drone industry, accounting for over 70% of the drone market.[3] Its drone technology has been used globally for the music, television and film industries, including K-pop music videos and the sets of Emmy Award-nominated television productions such as The Amazing Race, American Ninja Warrior, Better Call Saul, Game of Thrones, and many more.[4][5][6][7][8][9]

In 2017, DJI won a Technology & Engineering Emmy Award for its camera drone technology, which was recognized for excellence in engineering creativity, providing directors and cinematographers an affordable and accessible platform to create low-altitude aerial images, opening up creative possibilities and facilitating the distinct looks of some TV shows.[10]

History[edit]

The company was founded in 2006 by Frank Wang (Wāng Tāo, 汪滔).[11]

Wang, who hails from China’s Zhejiang Province, went to Hong Kong in 2003 after enrolling for a degree course in Hong Kong University of Science and Technology (HKUST). Two years later, the university granted him HK$18,000 (US$2,300) to conduct research and develop a drone. Wang founded the company in 2006 from his dorm room at HKUST.

DJI’s name stands for Dà-Jiāng Innovations, but it used to mean Dà-Jiāng Sciences.[12]

DJI manufactures a range of products including unmanned aerial vehicles, flying platforms, flight controllers for multi-rotors, helicopters accessories, aerial and handheld gimbals and ground stations.[13][14][15][16] These products are intended for amateur as well as professional use.[17][18] DJI product is sold directly on DJI's website as well as through Authorized DJI Dealers around the world.

The Mavic Air was announced on 23 January 2018, for release on 28 January. It is marketed as a smartphone-sized drone that can fit in a jacket pocket.

It features a 12 MP 4K HDR camera, mounted on a 3-axis gimbal, and has a new panorama mode, which stitches together 25 photos in eight seconds to create a "Sphere Panorama". Due to antennas mounted on its landing gear, the drone has a 21-minute flight time and a 2.5 mile range. Like the Spark, the Air also features the "Smart Capture" mode, in which the drone can be controlled by hand gestures.[31]

Matrice[edit]

DJI Matrice 200 Series, used by Deutsche Bahn

The Matrice (经纬) series are designed for industrial applications.

The Matrice 100 is a fully programmable and customizable drone, launched on July 6, 2015.[36] It has expansion bay and communication ports, which allows developers to add additional components for different purposes. [37]

Matrice 200 series is a range of weatherproof quadcopters from DJI announced in February 2017.

They are designed for industrial applications, including surveying, inspection, search and rescue and firefighting.[38]

The highest spec of the series is the Matrice 210 RTK, which features Real Time Kinematic technology, allowing for precise Geotagging of images captured from the quadcopter.[39]

The Matrice 200 only supports a single camera, mounted either below or above the drone.

The Matrice 210 and 210 RTK add the ability to dual mount cameras to the drone, allowing multiple sensors to be used simultaneously.[40]

Spark[edit]

A DJI Spark with its controller and an extra battery

Released in May 2017, the Spark (晓) was designed to be an affordable consumer drone that is nevertheless capable of producing high-quality images and video. This drone is DJI's cheapest to date and features a 12-megapixel camera capable of shooting 1080p video at 30fps. The camera is stabilised mechanically by a 2-axis gimbal. The Spark also carries an advanced infrared 3D camera that helps the drone to detect obstacles in front of it, as well as facilitating hand-gesture control—a feature that was, until the release of the Mavic Air in January 2018, unique to the Spark. In addition to a smartphone app with virtual controller, a physical controller can also be bought, extending the drone's range up to 1.2 miles (2 km). The aircraft has a flight duration of up to 16 minutes, but its exhausted battery can easily be swapped out for a charged battery to extend flight time.[41]

There have been multiple complaints that the drone could switch off and fall while flying[42]. DJI responded to this by releasing a mandatory battery firmware update in August 2017.[43]

Camcorders[edit]

Osmo[edit]

The Osmo (灵眸) is a camcorder developed by DJI. The camera uses a smartphone to view camera footage and can record 4K and take either 12–16 MP stills. The camera is interchangeable, with the Zenmuse X3, X3 Zoom, X5, and X5R gimbals compatible, and uses the FM-15 Flexi microphone.

Osmo Mobile[edit]

Similar to the Osmo, it instead relies on the user's smartphone as the camera. Most smartphones are accepted into the gimbal with a width range of 2.31–3.34 inch (58.6-84.8 mm). The original Osmo Mobile has reached its end-of-life and has been replaced with a second generation.[44]

Osmo Mobile 2[edit]

Announced after CES, the DJI Osmo Mobile 2 is the successor to the original Osmo Mobile. Still reliant on a smartphone camera, the Osmo Mobile 2 was a refinement adding multiple shot modes and increasing the battery life to 15 hours. With the rise of Instagram Stories, the Osmo Mobile also allows the gimbal to be placed in portrait mode.[45][46]

Goggles[edit]

DJI Goggles

The DJI Goggles [47] are comfortable goggles designed for FPV flying with DJI products. They combine a pair of screens, wireless connectivity, and direct control of photo and video capture. In November 2017, DJI presented a new, so-called 'Racing Edition' [48].

Market trends[edit]

As of March 2017, DJI has a 50 percent market share of the consumer drone market according to NPD numbers. Top line estimates from the FAA point towards the number of consumer drones hitting over 4 million units by 2021.[49][50][51]

Controversy[edit]

In January 2015, a DJI Phantom 3 crashed into the White House's south lawn, in Washington, D.C..[52] DJI later set up a no-fly Geo-system according to prohibited airspace, and forced all drones to update the firmware. The new system will forbid flights getting closer or take off in restricted zones based on its GPS location.[53]

Several military organizations also utilize DJI products for aerial photography mission including the US Army, and DJI drones were the most widely used commercial unmanned aerial system that the US Army has employed. However, on August 2017, the United States Army published internal guidance regarding the banning of using DJI drones and parts in the army for security reasons. DJI’s Public Relations Manager, Michael Perry expressed surprise and disappointment after the memo was released. A U.S. Army spokesperson responses to media and claim that the guidance is still undergoing a review.[54] Although US Army has stopped using DJI products, other branches of the US military such as the US Marines are still fielding DJI product as commercial photography platform.[55]

On November 17, 2017, Ars Technica reported a security breach of private customer data at DJI.[56] National Oceanic and Atmospheric Administration found no evidence showing DJI drones attempts to transfer data from the aircraft.[57] In 2017, DJI announced Local Data Mode for drones, which aerial platform will not enable any data transfer involving Internet during the flight. Brendan Schulman of DJI’s Vice President of Policy and Legal Affairrs denies the report from Ars Technica, saying “DJI is committed to protecting the privacy of its customers’ photos, videos and flight logs." DJI also emphasized that its drone never marketed toward the military user.[58][59]
