Using Photogrammetry to Quantify Vitiligo Lesions on Human Patients

Individuals diagnosed with Vitiligo are left with few treatment options or answers regarding the prognosis of their disease. The natural course of the disease is unpredictable and can spread to any area of skin on the human body. Unfortunately, researchers and physicians have not reached a consensus on how outcomes of Vitiligo treatments should be measured or assessed. Photogrammetry offers the advantageous ability to capture 360 degrees of a human subject in a uniform fashion. Through the creation of a 3D model and the use of computerized measurements, areas of affected tissue on a human model may be accurately quantified. This study looks at how photogrammetry and computerized measurements may be used to quantify the areas of skin lesions on human patients with Vitiligo. Accurate and precise calculations produced from this method can pave the way for a standardized approach to gaining quantitative data on this disease and the efficacy of treatments.
