Two image sensors simulate directly the way of disposing images with the human's two eyes, so it has important
value to apply to many domains, such as object identify, workpiece localization, robot navigation, and so on. This paper
focus on the object localization and distance detection based on two image sensors. It concentrates on how to apply two
CCD image sensors to object localization of a sphere in indoor environments. At first a space model of the two image
sensors was set up, then an experiment platform was built in order to prove the correctness and feasibility of that
localization algorithm, and the relationship between the coordinate localization accuracy and the sensor structural
parameters was analyzed. At the end the source caused to localization errors was found out by their characteristics.
