Low cost synchronized stereo aquisition system for single port camera controllers

This paper presents a method for creating a low cost stereo vision system which fits perfectly to the needs of cheap mobile robots. As mass-produced low cost CMOS cameras have no direct means for taking synchronized images, we present a method for taking synchronous images with these devices by manipulating their system clock. We also show a method of merging the data of two or more cameras for interfacing all of them to a single camera controller.
