R-JPEGs decoded
the way DJI intended
The R-JPEG looks like a photo and behaves like a measurement file — and most software treats it as the former. Atlas routes recognized DJI radiometric JPEGs through the DJI Thermal SDK; physical accuracy still depends on exact-model known-target certification.
Radiometric fidelity for DJI files
The difference between decoding an R-JPEG and merely displaying one is the whole product.
Radiometric file support
Atlas reads embedded temperature data from supported DJI R-JPEG and FLIR radiometric files — not just the colorized preview — and keeps measurement parameters available for review.
Radiometric temperature analysis
Inspect per-pixel temperatures, adjust emissivity and reflected temperature, and place spot and area measurements that update live as you tune parameters and interpret capture conditions.
Automatic photo organization
Uploads are sorted thermal vs optical, grouped by flight, and filed against the right project and building automatically — even full memory-card dumps.
Drone video frame extraction
Pull sharp, evenly spaced frames out of drone video — including thermal video — instead of screenshotting playback by hand.
Annotation & markup
Drop pins with live temperature readouts, mark regions, add delta-T callouts, and attach field notes so every finding carries its evidence.
Branded PDF reports
Generate client-ready reports with annotated imagery, findings tables, and severity grading — under your logo and brand, ready to send the same day.
Why naive R-JPEG parsing gets it wrong
Modern DJI thermal stills embed measurement data that requires the manufacturer's decode pipeline; shortcut approaches that scrape EXIF constants can produce temperatures that are wildly off without looking wrong. Atlas uses the DJI Thermal SDK for recognized R-JPEGs and flags unavailable measurements, without converting SDK parity into a physical-accuracy claim.
From single files to whole surveys
R-JPEG analysis at survey scale means handling the card, not the file: hundreds of stills auto-sorted from their optical twins, batch processing with per-image parameter adjustment where needed, and CSV export of full temperature matrices for downstream engineering work.
Frequently asked questions
What is an R-JPEG?
DJI's radiometric JPEG format combines a viewable thermal image with embedded temperature data. Supported software can recover a per-pixel temperature matrix and expose measurement settings; ordinary image viewers show only the colorized rendering.
Which DJI cameras produce R-JPEGs Atlas can decode?
Atlas uses model-specific profiles and the DJI Thermal SDK for recognized files. Compatibility must be checked for the exact camera, firmware, and format; one DJI model never certifies an adjacent model.
Can I export the decoded temperature data?
Yes — per-image temperature matrices export as CSV, alongside annotated imagery and reports.
