At the end of Sep­tem­ber, DJI intro­duced the Mav­ic 3 Enter­prise series of pro­fes­sion­al drones. The main nov­el­ty can def­i­nite­ly be called the Mav­ic 3 Ther­mal (Mav­ic 3T), equipped not only with a high-qual­i­ty 48 MP wide-angle cam­era, but also with a ther­mal imager with a res­o­lu­tion of 640 × 512 pix­els. Let us con­sid­er in more detail the scope and main capa­bil­i­ties of the new UAV.

Why is Aerothermography Necessary?

The range of pos­si­bil­i­ties for using drones is expand­ing every year. Along with it, the num­ber of pos­si­ble appli­ca­tions of drones in ther­mog­ra­phy (i.e. shoot­ing with a ther­mal imager) is grow­ing. We list the key areas where UAVs are becom­ing more and more in demand:

  • Fire­fight­ing. Drones can detect infrared radi­a­tion even through smoke and help fire­fight­ers find fires.
  • Search and res­cue oper­a­tions. In recent years, in many cas­es, drones have helped to find miss­ing peo­ple in moun­tain­ous areas, in areas with dense veg­e­ta­tion, as well as in oth­er hard-to-reach areas. Drones with a ther­mal imager are even more use­ful: they can be used at night and in thick clouds or fogs.
  • Fuel and ener­gy com­plex. Drones are used for inspec­tions of gas and oil pipelines, pow­er lines, off­shore drilling plat­forms — ther­mal imagers allow real-time detec­tion of leaks and con­trol of repair work.

Where are thermal imaging drones used today?

If ear­li­er, to con­duct a ther­mo­graph­ic sur­vey from the air, you had to choose a day with good weath­er and board a heli­copter (or even wait for data from a space satel­lite), then a mod­ern drone with a ther­mal imager removes a large num­ber of restric­tions. Here are spe­cif­ic exam­ples of the use of UAVs in aerother­mog­ra­phy:

  • Extin­guish­ing for­est fires in the Cher­nobyl exclu­sion zone. In April 2020, drones proved to be an indis­pens­able tool in the elim­i­na­tion of fires near the Cher­nobyl nuclear pow­er plant. Of course, the fires were not extin­guished by drones, but it was UAVs with a ther­mal imager that helped to iden­ti­fy the sources of fires, despite thick smoke, in con­di­tions where every minute mat­tered. You can read more about this oper­a­tion on the DJI blog.
  • Search for the miss­ing in the Russ­ian regions. The search and res­cue team “Lisa Alert” was able to find many lost chil­dren and adults thanks to DJI copters with a ther­mal imager. Drones allow faster inspec­tion of large areas, and a ther­mal imager sig­nif­i­cant­ly improves the effi­cien­cy of oper­a­tions at night and in win­ter.
  • Inspec­tion of oil and gas indus­try facil­i­ties. Glob­al fuel ener­gy giants such as Shell, Total­En­er­gies, Bak­er Hugh­es and Schlum­berg­er use pro­fes­sion­al drones with a ther­mal imager to detect cor­ro­sion, con­trol emis­sions of harm­ful sub­stances into the atmos­phere, and build accu­rate maps of new deposits.
  • Ani­mal res­cue on agri­cul­tur­al land. In the near-alpine regions of Europe, roe deer often died when har­vest­ing and sow­ing fields with the help of large agri­cul­tur­al machin­ery. At the ini­tia­tive of local res­i­dents, the spe­cial­ists of the agro-com­plex began to use drones to obtain ther­mal images of fields in order to quick­ly detect ani­mals and save them from death.

There is no doubt that in the near future ther­mal drones will be used in an increas­ing num­ber of indus­tri­al and high-end oper­a­tions, and the com­pact DJI Mav­ic 3T will make aer­i­al ther­mog­ra­phy a more acces­si­ble tech­nol­o­gy for spe­cial­ists from Rus­sia and oth­er coun­tries.

How Mavic 3 Thermal differs from other models

A mod­ern ther­mal imag­ing cam­era is not much dif­fer­ent from a con­ven­tion­al one, which is why the cre­ators of the Mav­ic 3T man­aged to make the new drone light­weight (it weighs 920g) and mobile (fold­ed dimen­sions — 22.1 × 9.6 × 9 cm). This did not affect the tech­ni­cal char­ac­ter­is­tics in any way — in one flight, the Mav­ic 3T is capa­ble of:

  • cov­er a dis­tance of 32 km;
  • reach speeds up to 54 km / h in nor­mal and up to 68 km / h in sport mode;
  • inspect an area up to 200 hectares.

The man­u­fac­tur­er equipped the quad­copter with an improved return-to-base (RTH) func­tion, an APAS 5.0 sys­tem for auto­mat­ic obsta­cle avoid­ance, and Ocu­Sync Enter­prise tech­nol­o­gy for con­trol­ling the drone at a dis­tance of up to 15 km. The 5000 mAh bat­tery allows the Mav­ic 3T to fly non-stop for up to 45 min­utes.

The Mav­ic 3T comes with the new DJI RC Pro Enter­prise con­troller. On it, in split-screen mode, oper­a­tors will be able to mon­i­tor the image simul­ta­ne­ous­ly from a ther­mal imag­ing cam­era and a con­ven­tion­al cam­era. The syn­chro­nous 28x image zoom will help you quick­ly deter­mine the exact loca­tion of the shoot­ing. The screen’s high bright­ness (1000 cd/m²) and 1920 × 1080 pix­el res­o­lu­tion make it easy to see details.

Mavic 3 Thermal may become one of the most sought after professional drones

The DJI Ther­mal Analy­sis Tool 3.0 will make it eas­i­er to iden­ti­fy tem­per­a­ture anom­alies in images tak­en by the Mav­ic 3T dur­ing inspec­tions. And as an acces­so­ry for the drone, you can pur­chase the RTK mod­ule, which pro­vides real-time cen­ti­met­ric posi­tion­ing accu­ra­cy and sup­ports GPS, Galileo, Bei­Dou and GLONASS.

Thus, Mav­ic 3T is real­ly, accord­ing to the man­u­fac­tur­er, a pro­fes­sion­al drone “for any task.”
