EYES IN THE SKIES The new flagship DJI all-in-one drones are the Matrice 4T and 4E, fully equipped with lots of sensors and multiple cameras
DJI’s new flagship UAVs use AI technology to fly safer Matrice drones elevate the game
T he Matrice 4 series is the new compact flagship of DJI’s enterprise drone series. The new Matrice 4T and Matrice 4E are intelligent, multi-sensor UAVs (unmanned aerial vehicles) with advanced smart detection and laser rangefinder measurement. A new AI platform and improved positioning sensors mean the Matrice series will be safer and more reliable than ever, DJI claims. Both drones are largely designed for emergency response teams or safety inspections, and feature three cameras. Both the £5910/$7299 4T model and £3940/$4799 Matrice 4E have a 70mm f/2.8 lens illuminating a 48-megapixel, 1/1.3-inch CMOS sensor plus a 168mm f/2.8 telephoto allied to a 48-megapixel, 1/1.5-inch CMOS sensor to get in close to the action. In addition, both models have a 24mm wide lens, the 4T model using a
definition, low-light fisheye lenses to allow for automatic obstacle avoidance, intelligent rerouting and safe return in urban low-light environments. In case of fog, haze or high humidity, the Electronic Dehaze function improves imaging clarity. The range of new accessories includes the AL1 Spotlight, to illuminate subjects up to 100 metres away. The AS1 Speaker delivers powerful audio up to 300 metres and reaching 114 decibels at one metre. The Multifunctional Station is a base station that offers improved positioning accuracy and extends image transmission. For fast take-offs and return-to-home functionality, there’s vision-assist in five directions, plus downwards, so the drone can fly without a GNSS signal.
faster f/1.7 version with a 48-megapixel, 1/1.3-inch CMOS sensor. The 4E version has a slower, f/2.8 lens and 20-megapixel, 4/3 CMOS sensor with a mechanical shutter. This allows high-speed aerial surveying from multiple angles as the drone supports rapid 0.5-second interval shooting and mapping of flight speeds up to 21 metres per second. With Smart 3D Capture, precise mapping routes can be generated on the remote controller. It can also display virtual space routes and waypoint photos. Both drones also have infrared thermal cameras that support high-res mode up to 1280x1024 pixels, while an auxiliary light can illuminate objects 100 metres away. Their laser rangefinders can measure distances of up to 1800 metres. A key upgrade to the Matrice 4 series is in night mode, thanks to their larger- aperture lenses and intelligent low-light capabilities. They also have six high-
