However, the technique remains essentially based on 2D images that display partial anatomy. In this context, a 3D thermal model provides improved visualization and faster inspection. This paper presents a 3D reconstruction method associated with temperature information. The proposed solution is based on a Structure from Motion and Multi-view Stereo approach, exploiting a set of multimodal merged images. The infrared images were obtained by automatically processing the radiometric data to remove thermal interferences, segment the RoI, enhance false-color contrast, and for multimodal co-registration under a controlled environment and a \u2206T &lt; 2.6% between the RoI and thermal interferences. The geometric verification accuracy was 77% \u00b1 2%. Moreover, a normalized error was adjusted per sample based on a linear model to compensate for the curvature emissivity (error \u2248 10% near to 90\u00b0). The 3D models were displayed with temperature information and interaction controls to observe any point of view. The temperature sidebar values were assigned with information retrieved only from the RoI. The results have proven the feasibility of the 3D multimodal construction to be used as a promising tool in the diagnosis of diabetic foot.<\/jats:p>","DOI":"10.3390\/s21113918","type":"journal-article","created":{"date-parts":[[2021,6,7]],"date-time":"2021-06-07T01:56:40Z","timestamp":1623031000000},"page":"3918","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Anatomical 3D Modeling Using IR Sensors and Radiometric Processing Based on Structure from Motion: Towards a Tool for the Diabetic Foot Diagnosis"],"prefix":"10.3390","volume":"21","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7198-2035","authenticated-orcid":false,"given":"Rafael","family":"Bayareh Mancilla","sequence":"first","affiliation":[{"name":"Departamento de Ingenier\u00eda El\u00e9ctrica\/Secci\u00f3n de Bioelectr\u00f3nica, Centro de Investigaci\u00f3n y de Estudios Avanzados del IPN, Av.
