Abstract
The present invention relates to a Method for Measuring the surface of the scalp for assessing bald areas (recipient areas), areas with thinning hair, and areas with thick hair (donor areas), using the counting of micropolygons in 3D models and/or 3D meshes created by technologies that generate full-scale 3D models. Additionally, the present invention pertains to a Method for Mapping the surface of the scalp to measure bald areas (recipient areas), areas with thinning hair, and areas with thick hair (donor areas). The invention also relates to a corresponding system and a computer program for these purposes

A method for Measuring the Surface of the Scalp for the Measurement of Bald Areas (recipient areas), Areas with Thinned Hair, Areas with Thick Hair (donor areas), using the counting of micropolygons in 3D models and/or 3D meshes created by technologies that generate life-size 3D models, the method comprising:
- Receive the 3D model and/or 3D mesh through the use of technologies equipped with mechanisms for capturing three-dimensional information;
- Delimit the area of interest through an interactive interface on the electronic device, directly on the virtual surface of the 3D model or 3D mesh, using any interactive interface designed to capture multiple input modalities;
- Process the micropolygons within the selected region, identifying the micropolygons that are fully or partially included in the demarcated area;
- Count the micropolygons to measure the area, determining the total area through the cumulative sum of the individual areas of the micropolygons that make up the selected region.
A method for Scalp Surface Mapping to Measure Bald Areas (recipient areas), Areas with Thinned Hair, Areas with Thick Hair (donor areas), characterized by the use of TrueDepth, Structured Light, LiDAR, Time-of-Flight (ToF) Sensors, Photogrammetry, Stereoscopic Vision, and similar technologies, for measuring bald areas (recipient areas), areas with thinned hair, areas with thick hair (donor areas), through the measurement of the surface of 3D models and/or 3D meshes created by these technologies or other similar technologies that generate life-size 3D models.
A method for Scalp Surface Mapping to Measure Bald Areas (recipient areas), Areas with Thinned Hair, Areas with Thick Hair (donor areas), characterized by the use of technologies equipped with mechanisms for capturing three-dimensional information, which will be used to generate a 3D mesh (“3D MESH”), serving as the foundation for rendering the 3D model of the patient's scalp for the mapping and measurement of bald areas (recipient areas), areas with thinned hair, areas with thick hair (donor areas).
Scalp Surface Measurement System for Measuring Bald Areas (recipient areas), Areas with Thinned Hair, Areas with Thick Hair (donor areas), using the counting of micropolygons in 3D models and/or 3D meshes created by technologies that generate life-size 3D models, characterized by, in an ideal application, comprising a camera hardware equipped with at least one three-dimensional information capture technology, an electronic device, and a measurement application or software installed on the electronic device.
Computer Program for Scalp Surface Measurement to Measure Bald Areas (recipient areas), Areas with Thinned Hair, Areas with Thick Hair (donor areas), using the counting of micropolygons in 3D models and/or 3D meshes created by technologies that generate life-size 3D models, configured to:
- Capture three-dimensional information of the scalp;
- Receive digital image data collected by technology equipped with three-dimensional information capture mechanisms;
- Analyze the captured images, identifying and correlating reference points that are matched across various images to compute the three-dimensional spatial coordinates of the scalp;
- Construct a 3D point cloud, which accurately represents the geometry and topography of the scanned scalp;
- Delimit, paint, and automatically record the region, generating a 3D mesh (3D MESH), which displays detailed and continuous visualizations of the scanned scalp surface;
- Create, from the 3D mesh (3D MESH), a continuous and detailed visual representation of the scanned scalp surface;
- Measure the area of the scalp through tactile interaction in the desired region;
- Display, for viewing through the electronic device, a simulated image of the scalp.
