A Review of ToF PMD Camera

摘要

The time-of-flight (ToF) camera is a basic component for the range measurement and Photonic Mixer Devices(PMD) uses this principle for constructing a 3-dimensional image. PMD combines the advantages of active sensors and provides accurate distance measurements and camera based systems recording a 2D matrix at a high frame rate. This paper focus on the different characteristics of this type of sensor such as integration time, modulation frequency and operating principle of the ToF Cameras. Different advantages such as registered depth and intensity data at a high frame rate, compact design, low weight, and reduced power consumption have motivated their increasing usage in several research areas, such as computer graphics, machine vision, and robotics are discussed.
