间接飞行时间图像传感器技术综述
Overview of indirect time-of-flight image sensor technology
摘要
Abstract
Three-dimensional(3D)imaging technology based on Time-of-Flight(ToF)belongs to active 3D imaging technology.It calcu-lates the distance information of the target object by measuring the time needed for modulated light to"fly"back and forth between the target object and the sensor.Compared to other 3D imaging methods,ToF-based 3D imaging methods have significant advantages such as miniaturization,simple structure,and low power consumption.With the development of technology,Indirect Time-of-Flight(IToF)image sensor pixel size gradually decreases,resolution increases,and accuracy improves,making it applicable in various scenarios.Howev-er,it still faces challenges such as background light interference,multipath interference,and motion artifacts.The working principle of ToF image sensors is introduced in section 1.The parameter indicators of ToF image sensors and their development trends are analyzed in section 2.The challenges faced by ToF image sensors are analyzed and the solutions are proposed in section 3.The image correction and restoration algorithms applied to ToF technology are introduced in section 4.关键词
