Real-world ther­mal im­ages

Be­ing able to share cam­era im­ages is a great ben­e­fit of ther­mal imag­ing tech­nol­ogy. How­ever, a ther­mal im­age alone is not al­ways enough to help your cus­tomers un­der­stand what they are see­ing. For this rea­son, Flir Sys­tems de­vel­oped the MSX multi-spec­tral dy­namic im­age mode.

MSX imag­ing brings to­gether both the vis­ual and ther­mal spec­trums, and is now on board most of the firm’s ther­mal cam­eras for the in­dus­trial and build­ing mar­ket.

MSX gen­er­ates a de­fin­i­tive, all-in-one ther­mal pic­ture that eas­ily ori­ents you to the lo­ca­tion of the prob­lem as soon as you see it on the screen or in a re­port. With the Flir for­mat you’ll save all im­ages with one push of a but­ton.

Key de­tails ap­par­ent to the naked eye such as num­bers, la­bels, sig­nage, and struc­tural fea­tures can get lost in a reg­u­lar ther­mal im­age. A reg­u­lar ther­mal im­age only dis­plays heat sig­na­tures, which can cause de­tails to get lost in the haze if they present a sim­i­lar tem­per­a­ture.

To over­come this, Flir cam­eras with MSX use an in­ter­nal dig­i­tal cam­era to en­hance the ther­mal im­age. The high­con­trast skele­tonised vis­ual im­age al­lows for key as­pects of the vis­i­ble spec­trum to be over­laid on top of the ther­mal out­put, while still keep­ing the im­por­tant ther­mal in­for­ma­tion prom­i­nent.

Ther­mal im­age with MSX. Note how the mo­tor num­bers are leg­i­ble.

Con­sider the el­bow con­nec­tors for ex­am­ple. Through the ther­mal cam­era you can see that one of the con­nec­tors is hot, and with your own eyes you can see a la­bel iden­ti­fy­ing each con­nec­tion on the panel.

But the ink on those la­bels is go­ing to have the ex­act same tem­per­a­ture as the sticker they are printed on, so your ther­mal imager will not dif­fer­en­ti­ate be­tween them. With MSX on the other hand this is clearly vis­i­ble in the im­age.

MSX tech­nol­ogy ex­tracts high-con­trast de­tails from the im­ages taken by an on board vis­i­ble light cam­era, and etches or su­per­im­poses them onto the ther­mal im­ages that the cam­era is tak­ing. This all hap­pens in real time, so what you see on­screen is a su­per sharp im­age that al­lows you to make out un­prece­dented de­tails in the im­age.

MSX uses vis­ual data from a dig­i­tal cam­era built into sev­eral mod­els of ther­mal cam­eras for the in­dus­trial and build­ing mar­kets. In­ter­nal soft­ware then an­a­lyzes the im­age from the cam­eras to su­per­im­pose the key as­pects of that vis­ual world onto the ther­mal im­age.

The vis­ual spec­trum never blots out the ther­mal side of things, mak­ing sure that all in­for­ma­tion is still at the high­est level of ac­cu­racy.

MSX en­sures eas­ier tar­get iden­ti­fi­ca­tion without com­pro­mis­ing ra­dio­met­ric data and the qual­ity of the ther­mal im­ages is ex­cel­lent. Thanks to MSX, ther­mal im­ages look sharper, the ori­en­ta­tion of the tar­get will be done quicker, the re­ports are clut­ter-free and en­sure a faster route to so­lu­tions. Users can see the re­sults of MSX tech­nol­ogy di­rectly on the touch screen of the cam­era, in real time.

Ther­mal imag­ing cam­eras of the past have fea­tured ways to blend, over­lay or fuse a por­tion of a ther­mal im­age into a vis­i­ble light pic­ture. But these modes have only pro­vided a par­tial so­lu­tion and typ­i­cally take ex­tra time to dial in and in­ter­pret. They also tend to limit or ob­scure the ther­mal view of the scene.

MSX is com­pletely dif­fer­ent. MSX tech­nol­ogy em­bosses dig­i­tal cam­era de­tail onto ther­mal video and stills. There­fore, MSX de­liv­ers much bet­ter, vis­i­ble re­sults than tra­di­tional meth­ods, which can di­lute the ther­mal im­age.

Ther­mal im­age with MSX: As com­pared to stan­dard ther­mal im­ages, MSX tech­nol­ogy al­lows for the ad­di­tional de­tec­tion of im­por­tant de­tails.
