Intelligent Space (iSpace) is a space which has ubiquitous sensory intelligence. In iSpace, positions of objects inside the space are one of the most basic information to implement various applications. This paper describes a method to localize the target objects using distributed laser range finders. Since data from a laser range finder is only distances and angles to object surfaces, we need to estimate the object center position based on its contour. To do this accurately, information of the target shape is utilized since there exist various iSpace applications where we can select the shape of the target object or attach markers of the selected shape to the object in advance. An experimental result is performed to evaluate the proposed method. Applications of the proposed method are also shown.
