Dinesh Balasubramaniam, Senior Product Marketing Manager at Ambarella, presents the “When 2D Is Not Enough: An Overview of Optical Depth Sensing Technologies” tutorial at the May 2021 Embedded Vision Summit.
Camera systems used for computer vision at the edge are smarter than ever, but when they perceive the world in 2D, they remain limited for many applications because they lack information about the third dimension: depth. Sensing technologies that capture and integrate depth allow us to build smarter and safer applications across a wide variety of applications including robotics, surveillance, AR/VR and gesture detection.
In this presentation, Balasubramaniam examines three common technologies used for optical depth sensing: stereo camera systems, time-of-flight (ToF) sensors and structured light systems. He reviews the core ideas behind each technology, compares and contrasts them, and identifies the tradeoffs to consider when selecting a depth sensing technology for your application, focusing on accuracy, sensing range, performance under difficult lighting conditions, optical hardware requirements and more.
