In this post we show you the right behavior to get an optimal face scan with ObiScanner.
In particular, we will analyze the question of the correct ambient brightness and the consequent positioning of the patient in relation to the light.
Correct lighting
To obtain a correct 3D model, you must perform the scan in a room that is not exposed to too many light sources. Using the integrated ObiScanner lights, optimal face scanning is achieved without needing to have other light sources behind or on the patient’s face.
—- Ideal brightness and positioning.
Behind lighting
If you perform a face scan with a light source behind the patient (for example, a window), the 3D model of the face will be dark, as in the image on the right.
—- Ideal brightness and positioning.
—- Light source behind the patient.
Lateral lighting
If you perform a face scan with a light source on the side of the patient (for example, a window), half of the 3D model of the face will be very bright and the other half will be poorly lit, as in the image on the right.
—- Ideal brightness and positioning.
—- Lateral light source.
