Abstract
A method for determining a position of a body having at least one marker object with a known dimension parameter. The method utilizes at least one camera unit having a sensor device and an optical element a determinable distance from the sensor device. The at least one camera unit includes an element for retrieving and calculation. The method includes the steps of computing the coordinates of an image of the object reproduced on the sensor device, computing a dimension parameter of the object corresponding to the known dimension parameter of the at least one marker object and calculating the proportion of parameters obtained to determine the position of the object.
