For demanding real-time object detection, Time-of-Flight (ToF) cameras using Sony’s new IMX556 DepthSense sensor have boosted speed, precision and accuracy but also simplified integration time and cost. To achieve the full potential of Time-of-Flight technology, some key factors should be considered. In this video we’ll talk about common challenges with ToF and some tips to help overcome them.
