When we measure the coordinate position exactly in the three-dimensional space from a target threshold, three range-finding devices are required. That is non-efficiency on a cost side. We suggest using Levenberg-Marquardt method to reduce the number of the devices to be necessary from three to two for this problem. In this study, we use Kinect for Windows version 1 provided by Microsoft Corporation for as a range-finding device. To estimate coordinate we use coordinates of two Kinect devices and each distance to object. We also review initial coordinate of the objects.
