Effective scan guidelines
The quality of your scan determines the quality of everything that comes from it - the 360° image quality, processing time, scan and issue locations, and AI progress tracking.
Before you start
Before hitting Start Recording, the Oculo mobile app shows you a pre-scan health check. Make sure all three are green:
|
🔋 Camera battery |
📱 Mobile device battery |
🗄️ Camera storage space |
|
Shown in the app before you start. Charge fully before going on site. |
A long scan on a low battery phone risks losing your session mid-walk. |
Shown in the app. Delete old published scans from the camera if space is low. |
Also check before you leave:
- Camera lenses are clean - wipe with the microfibre cloth. Even a fingerprint will affect image quality
- Use the Oculo mobile app - this ensures the right settings are used by the camera
- You have a high level plan for the floors you’re covering today
How to carry the camera
How you carry the camera is one of the biggest factors in scan quality. The camera needs a clear, unobstructed 360° view at all times.
The right way
- Hard hat mount (recommended for most internal scanning) - attach the camera to the mount on top of your hard hat. This keeps your hands free, the camera stable, and above head height.
- Selfie stick, camera held above head height - extend the selfie stick and hold the camera above your head. Better for low-clearance areas like scaffold, and for certain mobile lighting systems (see Scan Lighting article).
Why above head height?
Holding the camera above head height gives it the clearest possible view of the space. It reduces the chance of your body, arms, or equipment blocking parts of the 360° image.
On scaffold or external elevations, use a selfie stick and hold the camera in the hand closest to the building - this way your body faces outward and doesn’t block the facade
What not to do
- Don’t hold the camera directly in your hand at waist or chest height - your body will block a significant portion of the 360° view, reduce coverage quality, and impact processing (possibly resulting in a cancelled scan)
The 8 guidelines
Follow these guidelines for every scan.
|
1 |
📍 Set your start location accurately Why: Oculo maps your entire scan to the floor plan using your start point as the anchor. An inaccurate start location shifts the whole scan on the plan.
⚠️ An inaccurate start location is the most common cause of a scan appearing misaligned on the floor plan. Take 10 extra seconds here. |
|
2 |
💡 Check your lighting before you walk Why: 360° cameras need even, diffuse light across the whole space. Poor lighting causes grainy scenes, blurring, and location tracking problems.
⚠️ If an area is too dark to scan well today, note it and return when lighting conditions improve. A dark scan is worse than no scan - it can cause processing failures. |
|
3 |
🚶 Walk like you’re carrying a cup of coffee Why: The camera captures a frame every 0.5 seconds in Timelapse mode. Move too fast and you’ll have gaps in coverage. Move too erratically and the image quality drops.
|
|
4 |
🔄 Walk around the perimeter of every room Why: Walking through the centre of a room leaves the corners and edges under-captured. Walking the perimeter gives comprehensive coverage of all surfaces.
⚠️ Missing rooms is one of the most common feedback points from office-based teams reviewing a scan. If it’s on the floor plan, scan it. |
|
5 |
⬆️ Use stairs between floors - not lifts or hoists Why: Oculo tracks your movement continuously to stitch the scan across floors. A lift or hoist breaks that spatial continuity and causes the scan to fail across floors.
⚠️ Using a lift mid-scan without stopping will cause processing delays, and possible floor allocation problems. |
|
6 |
📹 Record everything in one continuous scan Why: Oculo works best with one long, continuous recording per site visit. Multiple short scans mean manual stitching and gaps in the coverage timeline.
|
|
7 |
🧹 Camera care and maintenance Why: A dirty lens or a scratch may be invisible to the eye but immediately obvious in the 360° output. Dust, fingerprints, and debris cause blurring that affects both image quality and AI accuracy.
|
How often to scan
The more frequently you scan, the more useful Oculo becomes - both for 360° documentation and for progress tracking.
Recommended cadence
Aim for one comprehensive scan per week as a minimum. A weekly scan gives your team an accurate, up-to-date record of progress and gives the AI enough data to track trends and identify bottlenecks.
For fast-moving phases or compliance-sensitive work (e.g. pre-pour inspections, cladding installation, fire stopping), scan more frequently - daily if the work warrants it.
A scan takes roughly the same time as a normal site walk. Build it into your existing routine rather than treating it as a separate task.
Scanning outdoors
Scanning outdoors follows the same principles as internal scanning, with a few adjustments for the environment.
- Ensure that you have provided a site plan so that you can select an accurate start and end point, and so the site plan can be used for processing outdoor sections of your scan
- Choose a good reference point on the site plan as a starting location, one where you can be sure that it is accurate (eg a site entrance, or an existing building - not in the middle of a large open area)
- Try to avoid rain - the cameras are water resistant, but the lenses will get covered in raindrops affecting your image quality. If they do get rained on, try to dry them off regularly, and ensure they are dried off before scanning internals.
Scanning scaffold and external elevations
Scaffold and external areas again follow the sameprinciples, with a few adjustments for the environment.
- Use a selfie stick rather than a hard hat mount - scaffold often has low clearance, and the selfie stick gives you more control over camera position
- Hold the camera in the hand closest to the building - this way your body faces outward and doesn’t block the facade from the camera’s view
Common mistakes and how to avoid them
These are the most frequent issues that lead to poor scan quality or a Cancelled scan. If your scan looks wrong after processing, check this list first.
|
Mistake |
What goes wrong |
How to avoid it |
|
Rushing through rooms |
Gaps in coverage, missed areas, low image quality |
Walk like you’re carrying a cup of coffee. Pause in small rooms. |
|
Poor or uneven lighting |
Grainy images, blurred images, processing failures |
Turn on all static lighting. Use a diffuse light attachment in dark areas. Never use a beam torch. |
|
Dirty camera lenses |
Blurry or smeared images across the entire scan |
Wipe both lenses with the microfibre cloth before every scan. |
|
Holding camera in hand at body height |
Body blocks parts the 360° view, processing problems, cancelled scans |
Hard hat mount or selfie stick held above head height. |
|
Missing rooms (toilets, plant rooms, storage) |
Gaps in site record, coverage complaints from office team |
If it’s on the floor plan, scan it. Plan your route before you start. |
|
Inaccurate start or end location |
Scan appears misaligned on the floor plan, processing delays |
Zoom in and place the pin precisely on a recognisable fixed point. |
|
Using a lift mid-scan without stopping |
Processing delays |
Stop the recording before entering any lift. Start a new scan when you exit. |
|
Not using Oculo mobile app |
Unsupported recording modes, processing delays, cancelled scans |
Always use Oculo mobile app |
What a good scan looks like
When your scan is published, you and your team should be able to:
- Navigate every floor and room of the scanned area from the floor plan
- See clear, sharp 360° images in every scene - no blurring, dark areas or grainy images
- Identify exactly where each scene is on the floor plan - the path should match your walking route
- Compare this scan against previous scans of the same area to see clear progress
Not quite right?
If your published scan has blurry images, stitching errors, or appears misaligned on the floor plan, check the Common mistakes section above and note what might have caused it.
Email help@oculo.ai with the scan name, site, and a description of what looks wrong. Include the video playback link if available - we can help you diagnose the issue quickly.
