About
Sergey V. Alexandrov is a robotics researcher whose work focuses on the calibration and enhancement of low-cost 3D sensing systems. His key contributions lie in addressing the optical imperfections of consumer-grade RGB-D sensors, which are widely used in robotics and computer vision. In his highly cited 2016 paper, "Calibration and correction of vignetting effects with an application to 3D mapping," Alexandrov tackled the problem of vignetting—the darkening of image corners—that plagues sensors like the Asus Xtion Live Pro, where corner pixels can be up to two times darker than the center. He developed a method to calibrate and correct these nonlinearities, significantly improving the accuracy of 3D mapping in real-world environments. This work has garnered 14 citations, demonstrating its relevance to researchers seeking to enhance the reliability of affordable depth cameras. Alexandrov’s research bridges the gap between cost-effective hardware and high-fidelity spatial data, making him a notable figure in the field of robotic perception and sensor calibration.
