Stereo Vision and Its Application to Robotic Manipulation

Distance Measurement Using a Stereo Vision System

“…What distinguishes these two types is the capacity of the sensors to output energy to the world. As an example of active sensors, a laser sensor measures the distance using the duration since the light is emitted until it captures the reflected light [2]. On the other hand, among passive sensors, stereo vision is the simplest device to obtain 3D information.…”
