Abstract

3D surface imaging can potentially play a crucial role in oculofacial surgeries. Associated 3D measurements can facilitate surgical planning and postoperative assessment. Further, lifelike 3D visualization of human face is helpful as a communication/training tool for medical professionals/trainees. In this backdrop, we present a 3D surface imaging and measurement platform that is both flexible and accurate. Specifically, our systems consists of a stereo camera and two monocular cameras, which can be individually positioned and focused to obtain crisp images. From those images, true-to-scale reconstruction was achieved with accuracy levels between 97.46% and 99.83% in various oculofacial measurements. Significantly, such levels of accuracy are comparable to those achieved by inflexible legacy systems. Additionally, our system, consisting of discrete cameras, requires minimal training to operate, and hence could find use in telemedicine.
