Chung Yuan Christian University is a private university in Zhongli District, Taoyuan City, Taiwan. The university was established as Chung Yuan Christian College of Science and Engineering in 1955 by a group of Taiwanese and American Christian educators to train science and engineering talent in the Christian spirit. The school was upgraded to a full university and renamed Chung Yuan Christian University in 1980. Wikipedia.

A method of building a stereoscopic model with Kalman filtering (KF) is provided. The method entails capturing images of the environment with a sensing device to build the stereoscopic model and then correcting a static object and a dynamic object in the environmental images with Kalman filtering to enhance the accuracy of the stereoscopic model. The prior art is a great reduction of accuracy in simultaneous localization and mapping (SLAM) in the event of increased system variation, increased complexity, or increased involved field. The method overcomes a drawback of the prior art.
