1. An apparatus for measuring a location and a distance of an object by using a camera comprising:

  • a camera module for photographing an external image;

    a parameter setup unit for setting internal and external parameters of the camera module;

    an image processor unit for receiving a captured image of an image photographed from the camera module, extracting a target object within the captured image, and extracting specific point coordinates of the extracted target object; and

    a location and distance calculating unit for calculating three-dimensional object location information from a two-dimensional camera coordinate system through the internal and external parameters of the camera module and the specific point coordinates of the target object extracted by the image processor unit, and calculating distance information from the three-dimensional object location information of the object.
