Abstract: This thesis presents the research and development of a novel procedure for creating a 3D image of the back using stereo digital 2D images. The procedure requires minimal user input and is intuitive. The procedure is comprised of 3 stages – image data acquisition, image registration and image reconstruction. Back Image data was acquired using automated template matching of a pegboard in a unique stereo camera configuration that improves speed over existing processes. To improve the registration process, a new approach combining image segmentation and differential geometry with belief propagation was developed. Stray data points were removed in the 3D Back image reconstruction process and missing data points were interpolated using a unique method of Moving Least Squares – Bezier Curve. The procedure was tested on human subjects. The results demonstrate that the procedure can be used clinically to obtain 3D back images for the evaluation of scoliosis.
