Wang's research focuses on 3D computer vision, especially in developing robust, efficient and easy-to-use CV algorithms and systems, with a research objective to benefit the society at large instead of just for the CV community. To this end, his research group develops 3D technologies that use pictures from mass-market, consumer-grade digital cameras, camcorders, and phones without the need of any special equipment, setup, calibration, markers, user training, or manual intervention.
