The present invention relates to a calculation and simulation-ray field, the visibility optimum based on the marker position in the object tracking optical system by simulating (visibility) haha ​​includes a method. The camera and the reference position and pose prediction algorithm method for optimizing the tracker system to be realized in order to simulate the parameters, the mesh data and the possible poses of the tracking object, which represents the possible active marker position and orientation in the tracking object so as to optimize the system and a pause data representing, comprising: obtaining the camera position and orientation; Calculating the visibility of each node from all the camera viewport, and also generates a list of values ​​visible; FIG highest visible selecting the node with the count as a marker arranged node; Removing a node closer to the selected node than the threshold; Removing the pose (s) having a selected node of the predetermined number; Determining all pose it has the selected node in the number percentage of a pre-determined; And to project the selected node is located in the image plane of each camera viewport, using the tracker algorithm is optimized calculating a pose of the mesh; Calculating a pose error and pose coverage by comparing the result of the algorithm and the initial data; The step of recording and outputting the result; And the result comprises the step of selecting at least a set of parameters that satisfies a limitation on the way.
