In late years, the setting number of the surveillance cameras increases by for the purpose of security. The problem is the difficulty for a person to see all the pictures of the surveillance cameras, and the automation of the monitor is demanded. In this study, we introduce a labor saving method into the acquisition of the extrinsic parameters of cameras. We then develop a cooperated multi-cameras system which is calibrated in this way and is aimed at construction of security environment for burglers and suspicious objects.
