FAQ

See the pricing section for each plan. There are 1-year and perpetual licenses; a perpetual license lets you keep using the version you bought with no time limit.

The following features are available on the PRO plan only.

• Orthomosaic generation
• 3D model generation
• Report export
• Scale settings
• Set link
• Same-location search
• Measurement review

On LITE you can still preview reports, and view and measure orthomosaics and 3D models that have already been generated. In the app, PRO-only features are marked with a crown icon. See Plans and features for details.

It is the fee for using newer versions. Once paid, you receive updates for the following year.

• The perpetual license price does not include the annual system update fee. If you want updates, it is paid separately
• If you don't pay it, you can keep using the version you have with no time limit
• You can pay whenever you like — for example every other year, only in the years you need it
• Resuming after a gap involves no back-billing or re-subscription fee

See Plans and features for details.

No. It is a paid option for those who want it. We recommend it if you are not comfortable with PCs, or if you would like a walkthrough from importing images to exporting a report.

Yes. Please request one through the contact form, letting us know:

• LITE or PRO
• 1-year or perpetual
• Whether to include onboarding training
• For a perpetual license, whether to include the annual system update fee

Yes. Payment is handled by Stripe, by credit card or bank transfer. Invoices are issued in US dollars.

We offer a 14-day free trial with every PRO feature unlocked. We can start it on the date you prefer — apply through the contact form.

CRITIR is eligible for Japan's "Digitalization and AI Adoption Subsidy".

• ASOLAB, as a registered IT adoption support provider, helps with the application
• We can also introduce an administrative scrivener who helps prepare the paperwork
• Review takes about one month from application

See the subsidy page (in Japanese) for cost estimates and the application flow.

Yes.

No — this subsidy covers software only. Prefectural or local subsidies may be available for hardware.

By online activation with a license key — no USB dongle or other hardware is involved. Once activated, the app keeps working offline for a certain period.

Yes. One license key can be installed and used on any number of PCs. Replacing a PC, or switching between an office desktop and a field laptop, needs no special procedure.

However, one license key cannot run on multiple PCs at the same time. To use CRITIR on several PCs simultaneously, you need additional seats.

Yes — once installed, viewing, analysis and report export all work offline. However, license activation and automatic weather data retrieval for reports (AMeDAS) require an internet connection. When offline, enter the weather data manually.

For heavy 3D model generation, we recommend an NVIDIA GeForce RTX (8 GB+ VRAM), 32 GB+ memory, and an NVMe SSD with tens of GB free for projects. See Installation for details.

Yes. Without a GPU, the CPU builds 3D models of the same quality. A GPU (NVIDIA, AMD or Intel) makes processing faster.

With many photos (say, over 700), a laptop without a GPU can take tens of hours. If processing seems extremely slow, send us the file from Settings ▾ → Export Logs... in the toolbar and we will look into the cause.

CRITIR supports infrared cameras from DJI, FLIR, HIKMICRO, Fluke, Skydio, Autel, NEC Avio and testo. See the supported cameras list for models. For cameras not on the list, you can send a camera support request.

Note that the DJI Mavic 2 Enterprise Dual does not record temperature in its photos, so temperature analysis is not possible (its visible images can still be used).

There are no model restrictions for visible-light cameras (see the next question).

Yes. There are no model restrictions for visible-light cameras. Images from any camera — DSLRs, mirrorless and compact cameras, smartphones, drones with only a visible camera, and so on — can be loaded. JPEG, PNG and TIFF are supported (convert iPhone HEIC files to JPEG first).

With visible images alone you can:

• Run image linking and generate orthomosaics and 3D models
• Measure lengths and areas (set up scale to measure in real-world units)
• Export reports (such as the visible photo ledger)

Visible images can also go in the same set as infrared images and be processed together. Model restrictions apply only to infrared cameras (for reading temperatures and aligning infrared images with visible images).

Yes, but mind how you name them. CRITIR pairs infrared and visible images mainly by filename. Files with the names the camera gave them pair correctly as they are.

If you rename files, follow these rules.

• Keep the infrared and visible images in the same folder
• Use the same base name and end infrared files with _T and visible files with _W (or _V) — e.g. BldgA_001_T.JPG and BldgA_001_W.JPG
• Do not strip the capture metadata (date/time, camera model, etc.)

For cameras that save infrared and visible images under offset numbers — Mavic 2 Enterprise Advanced, Zenmuse XT2, FLIR cameras, etc. — keep the original filenames.

First, check the supported cameras list.

Because the thermal camera and the visible camera are physically offset, a slight misalignment can occur depending on the shooting conditions. Use the Alignment Adjustment feature if needed. For supported models (DJI M3T / M30T / H20T / H30T), once you run image linking you can use Precise alignment, which uses the image-linking result to align each shot taking depth into account. See Fine-tuning alignment for details.

If the misalignment is large, contact us via the form below.

Yes. Image linking and orthomosaic generation work. Real-world dimensions are not determined automatically, though, so set up scale if you need to measure distances or areas. Such images cannot be shown on a map.

No. Images captured with a standard GPS drone can still be used for image linking, wall-surface orthomosaics and 3D model generation.

For images captured with an RTK-capable drone, a fast processing path that leverages the high-precision position data is applied automatically: image linking time is reduced significantly, and alignment accuracy and stability also improve. This fast path only applies to images recorded while RTK was in a FIX (fixed solution) state. Images captured without a fix (Float, standalone positioning, etc.) go through the standard processing path.

There is no single answer, because the best window differs per face. An east face gets sun in the morning and a west face in the afternoon, and in practice neighbouring buildings and terrain cut those hours down further.

The free web tool Thermal Planner takes an address and simulates sunlight and shadow for each face of the building, giving you recommended windows and a printable capture plan before you leave. See Capture planning (Thermal Planner) for how to use it, and Shooting tips for conditions on the day.

No. Thermal Planner is free, needs no account, and runs in any browser. It does rely on Project PLATEAU and Geospatial Information Authority of Japan data for building geometry, so it covers Japan only and its interface is in Japanese.

• Overlap: aim for 60–70% overlap on the infrared images, or 70–80% on the visible images. Camera positions are worked out from the visible images, so 60% on the infrared side is enough
• Zoom: don't use digital zoom. Optical zoom is fine, but it narrows each photo's footprint — make sure the overlap is still sufficient
• Angle: shoot as square-on to the wall as possible. Planar orthomosaics favour photos taken from the front
• Wide shots: add a few photos taken while gradually backing away, showing the wall and its surroundings — this stabilises alignment

When building an orthomosaic from a 3D model, adding oblique photos improves the result. See Shooting tips for details.

Yes, if you want to measure distances or areas in real-world units.

1. Open Process ▾ → Scale Settings
2. Click two points whose distance you know and enter that length
3. Registering 2–4 distances improves accuracy

For images with GPS, the scale is estimated automatically, but distances you register manually take priority. See Scale settings for details.

Try the remedy that fits the situation.

See Orthomosaic generation and Unwrapped ortho for details.

By default, only images with measurements are exported. To include images without measurements, uncheck "Exclude images without measurements" under Display Filters on the report screen.

Note that the standard template always exports only images with measurements, regardless of this setting.

Yes. Set this under Common Settings → Advanced Settings on the report screen.

• Measurement zoom: enlarges the measured area. Choose 1.5× to 8×, or Auto (fit to measurements)
• Use zoom image for visible: overlays the zoom-camera image onto the matching area of the visible image

In custom templates, you can choose image types such as "Infrared (zoomed to measurements)" or "Zoom camera (aligned to visible)".

Yes.

1. On an image-linked orthomosaic (or 3D model), outline one tile with the area tool — trace the centre lines of the joints for an accurate count
2. Right-click that measurement and choose Set as Tile Reference
3. Area measurements made afterwards show "Tile auto area: ≈N tiles" in the inspection results

To include the counts in the deterioration quantity summary, check Show tile count column.

Yes. In the ortho viewer, use Input ▾ → Add Blueprint File to load DXF, PDF or image drawings. To align, click the same four points on the orthomosaic and on the drawing. See Ortho viewer for details.

Mainly PDF and Word (.docx). Depending on the template, the deterioration quantity summary can also be exported to Excel and the deterioration map to DXF (CAD). Custom templates export to PDF only.

The following can be customized.

• Paper size (A4 / A3 / Letter) and orientation (portrait / landscape)
• Which pages to include (cover, survey overview, equipment, overview, detail sheets, summary tables)
• Cover page information (client, title, property name, survey date, logo, etc.)
• Detail sheet layout (auto / wide top / tall left / stacked)
• Editing of weather data, environmental assessment, and equipment information
• Display filters (which types and measurement tools to include, excluding images without measurements or with no anomaly, and so on)
• Six built-in templates (standard, photo ledger A/B, visible photo ledger, deterioration map, deterioration quantity summary), plus free layouts made with the template builder

See Report creation for details.

When a new version is released, the app shows a notification. You can also download and install the latest version from the download page.

Yes. From the project list screen, export the project as a .critix file and import it on the destination PC. Measurement results, orthomosaics, 3D data, and more are carried over. See Export for details.
