How to perform a 3D head scan with a smartphone

A 3D head scan now makes it possible to capture the head and face directly from a smartphone, without specialized hardware.

Thanks to mobile 3D scanning and photogrammetry, it is possible to generate a precise 3D model that can be used for professional applications: product personalization, virtual try-on, avatar creation or the design of devices adapted to the user’s morphology.

In this article, discover how to 3D scan your head with a smartphone, and how this technology can enhance the customer experience while simplifying professional workflows.

3D head and face scanning with a smartphone

Smartphones now make it possible to perform a 3D head scan directly from a mobile device, without a dedicated scanner.

Some technologies rely on specific sensors, such as LiDAR or the TrueDepth camera on certain Apple devices. However, for more flexible professional use cases, MyFit Solutions now favors mobile photogrammetry, based on the rear cameras of iOS and Android smartphones.

This approach captures multiple images of the head and face from different angles in order to reconstruct a precise and usable 3D model.

At MyFit Solutions, the goal is to make 3D capture simpler, more accessible and better adapted to professional use cases: product personalization, virtual try-on, 3D avatars, medical devices or morphological analysis.

How to 3D scan your head with a smartphone

Here are the 3 key steps to perform a 3D scan of the head and face using a MyFit Solutions application.

1. Prepare the environment and the person being scanned

Before starting the scan, it is important to prepare a suitable environment. Use even lighting and avoid backlighting, direct sunlight or strong shadows.

The face should be clear to make it easier to capture volumes and details. Depending on the use case, it may be useful to pull the hair back or cover it with a cap.

Throughout the capture process, the person being scanned should remain still and keep the same facial expression. This stability helps generate a more precise and consistent 3D model.

The distance between the smartphone and the person being scanned should remain consistent throughout the capture. This helps generate more homogeneous data and reduce distortions in the 3D model.

With MyFit Solutions, the scanning experience is designed to be easy to use, without heavy technical training or specialized scanning hardware.

3. Access the 3D head model

Once the scan is completed, the 3D head model can be accessed directly from the smartphone or through the connected web platform.

The generated models can be exported in .stl or .obj formats and integrated into existing tools and workflows through standard connectors, such as APIs or Webhooks.

A 3D head scan therefore makes it possible to quickly obtain a usable model, without specialized scanning hardware. This model can then support many professional applications: product personalization, virtual try-on, 3D avatars, custom device design or morphological analysis.

How to use a 3D model of the head and face

3D capture of the head and face opens up a wide range of professional applications, especially in healthcare, luxury, custom-fit products and customer experience.

With a usable 3D head model, professionals can rely on precise morphological data to design better-fitting products, create more immersive experiences or support visual analysis over time.

Analyze and monitor morphological changes

In healthcare, 3D scanning can help document and monitor morphological changes in a specific body area, whether in a clinic, healthcare facility or remotely.

For example, torso 3D scanning can be used to monitor patients with scoliosis over time, providing healthcare professionals with visual data to support patient follow-up.

For the head and face, this same approach can support visual analysis, follow-up and comparison over time, giving healthcare professionals access to a precise and easy-to-review 3D model.

Create custom-fit products

3D head scanning can also support the design of custom-fit products adapted to each user’s morphology.

In healthcare, this can include the creation of masks designed for specific needs, such as devices used for sleep apnea treatment or respiratory support.

It can also support the design of personal protective equipment (PPE), such as helmets, by helping adapt the product to the exact shape of the head.

In eyewear, 3D capture of the head and face can help take into account each customer’s anatomical features to offer frames that are more comfortable, better fitted and better adapted.

Create immersive customer experiences

In the luxury sector, 3D head scanning goes beyond product personalization. It can help create premium customer experiences based on photorealistic 3D avatars that reflect the customer’s real dimensions.

These digital twins allow professionals to present custom creations, design better-fitting jewelry or prepare precise size adjustments before production.

For brands, this approach creates a more exclusive and personalized experience while making remote collaboration and product visualization easier.

A 3D head scan is therefore a valuable tool for professionals who want to personalize products, improve the customer experience and integrate morphological capture into their business workflows.

At MyFit Solutions, we develop mobile 3D scanning solutions designed to simplify 3D acquisition from smartphones, without specialized hardware, while generating models that can be used for professional applications.

Why use a smartphone instead of a dedicated 3D scanner?

Mobile 3D scanning makes it possible to capture the head and face without relying on specialized scanners, which are often expensive, complex to maintain and harder to deploy at scale.

With a solution based on the rear cameras of iOS and Android smartphones, professionals can perform 3D captures directly in the field, in store, in clinic or remotely.

This approach makes team onboarding easier, simplifies workflows and allows 3D models to be integrated more easily into existing business tools.
