ABSTRACT:
An embodiment may comprise a camera based target coordinate measuring system or apparatus for use in measuring the position of objects in manner that preserves a high level of accuracy. This high level of measurement accuracy is usually only associated with more expensive laser based devices. Many different arrangements are possible. Other embodiments may comprise related methods of using a camera based target coordinate measuring method for use in measuring the position of objects. Many variations on the methods are possible. For example, an embodiment may comprise a camera based coordinate measuring system for use in measuring the position of a target relative to at least one frame of reference without requiring use of a laser range finder for measuring distance comprising: at least three or more light sources located on a target at known three-dimensional coordinates relative to each other; at least one rotatable camera rotatable on about a first axis and a second axis wherein the camera records positions of the light sources; and two angular measuring devices to measure the angles of rotation of the camera about the first and second axes; and a processor for determining up to three positional degrees of freedom and up to three rotational degrees of freedom of the target.
