title: Computed tomography as ground truth for stereo vision measurements of skin.
abstract: Although dysesthesia is a common surgical complication, there is no accepted method for quantitatively tracking its progression. To address this, two types of computer vision technologies were tested in a total of four configurations. Surface regions on plastic models of limbs were delineated with colored tape, imaged, and compared with computed tomography scans. The most accurate system used visually projected texture captured by a binocular stereo camera, capable of measuring areas to within 3.4% of the ground-truth areas. This simple, inexpensive technology shows promise for postoperative monitoring of dysesthesia surrounding surgical scars.
