Quickstart

This guide walks you through the full workflow: shooting → creating a project → generating an orthomosaic → overlaying blueprints → analysis and measurement → report export.

Detailed settings for each step are covered in the individual guide pages. The goal here is to get through the whole workflow once, end to end.

1. Shoot

Analysis quality in CRITIR depends heavily on the captured data. Keep the following points in mind before heading to the site.

1-1. Shooting essentials

• 70–80% overlap — capture images so that adjacent shots overlap sufficiently. This directly affects the accuracy of orthomosaic generation (SfM)
• Face the wall head-on — avoid extreme oblique angles; shoot as perpendicular to the wall surface as possible
• Cover everything in a grid pattern — sweep the surface top to bottom and side to side without gaps
• Do not use zoom — changing the field of view can reduce SfM accuracy and cause alignment problems with the infrared images
• Use one folder per wall surface — keeping each wall you want as an orthomosaic in its own folder makes later processing much easier

1-2. Tips for generating clean orthomosaics

In addition to the shots needed for a normal inspection, capture wide-area shots of the target while gradually moving away from it where possible. Adding wide-area images improves SfM reconstruction accuracy, making it much more likely that you get a clean orthomosaic with few visible seams.

See Shooting tips for details

2. Create a project

When you launch CRITIR, the project list screen appears.

2-1. Create a new project

Click "+ New Project" in the top right.

12345

• Project name — enter an easily recognizable name, such as the building or site name
• Description — optional; useful for notes

2-2. Configure sets and image folders

A set is a unit for grouping images. Orthomosaics are generated per set, so the usual approach is to create one set per building face (north face, south face, and so on).

1. Enter a set name (e.g. North face)
2. Use "+ Add Image Folder" to select the folder containing the captured images (you can also drag & drop folders)

If the building has multiple faces, click "+ Add Set" to add as many sets as you need.

2-3. Finish creating the project

Click "Create". The images are scanned automatically and the main screen opens. The paired images appear in the image list on the left side of the screen.

See Project management for details

3. Generate an orthomosaic

An orthomosaic is a single, front-facing image composited from multiple shots. Generating one not only gives you an overview of the entire wall surface — it also links the positions of the individual images, so measurement results are shared across images and onto the orthomosaic.

3-1. Launch the wizard

Launch the wizard in either of the following ways.

• Toolbar Process ▾ → Image Linking, Ortho, and 3D Generation (choose Orthomosaic in the left rail of the wizard)
• The Generate Orthomosaic button in the minimap at the bottom of the right panel (shown while no orthomosaic exists)

3-2. Output settings

The default settings are recommended in most cases.

See Output settings for details

The target is the set currently open in the main window.

3-3. Select the target plane

Candidate planes automatically detected from the image linking (SfM) results are displayed. Select the target wall surface. The candidate with the "Recommended" badge is usually the best choice.

If needed, fine-tune the orientation with the rotation buttons.

3-4. Scale setup (optional)

1234

You can calibrate the real-world scale of the orthomosaic by marking two points with a known distance between them. This step can be skipped.

See Orthomosaic generation for details

4. Overlay a blueprint

Once the orthomosaic has been generated, you can load a blueprint and overlay it on the ortho. This is also used when creating deterioration maps for reports.

4-1. Load a blueprint

Go to Input → Add Blueprint File to load a blueprint (DXF / PDF / JPG, etc.) and align it with the orthomosaic. Click four points that mark the same locations, in order, on both the orthomosaic and the blueprint.

See Loading and aligning a blueprint for details

5. Analyze and record

Analyze the images and record your findings using the tools below.

5-1. Switch between images

Click an image in the image list at the bottom of the screen, or use the ← → keys to switch images. Press SPACE to jump between the ortho viewer and the main viewer.

5-2. Switch display modes

Use the display mode button on the toolbar, or press 1–8 on the keyboard, to switch display modes.

5-3. Adjust the temperature display range

Use the temperature slider at the bottom of the screen to adjust contrast.

• Drag the blue handle (low end) and red handle (high end)
• Drag between the handles to slide the whole range
• Double-click to cycle through percentile presets (95% / 98% / 100%)
• Right-click → Lock to fix the temperature span

5-4. Measure anomalies

Select a measurement tool from the tool icon bar at the left edge of the window, or switch tools with the shortcut keys.

Measurement results are listed in the Inspection Results panel on the right side of the screen. For each measurement you can set a type (delamination, crack, water leak, etc.) and a judgment (Normal, Needs Review, Needs Correction, etc.).

6. Export a report

Once measurement and judgment are complete, export the inspection report.

6-1. Open the report creation screen

Select Export menu → Create Report on the toolbar.

6-2. Choose a template

6-3. Check the preview and export

Check the result in the real-time preview in the right panel, and click "Export Report" when you are satisfied.
