Apparatus for calculating 3D spatial coordinates of digital images and method thereof

An apparatus, comprising:

• a digital photographing apparatus for calculating 3D spatial coordinates of digital images, comprising:
• an image acquiring unit that acquires images by photographing a subject;
• a sensor information acquiring unit that acquires positional information, directional information, and posture information of the digital photographing apparatus at the time of photographing a subject;
• a device information acquiring unit that acquires device information of the digital photographing apparatus at the time of photographing a subject;
• and
• a spatial coordinates calculator that calculates 3D spatial coordinates of photographed images using the acquired positional information, directional information, posture information, and device information,
• wherein the device information of the digital photographing apparatus includes at least one of view angle information, focal length information, expansion information, and reduction information,
• wherein the sensor information acquiring unit includes a directional information acquiring unit and the directional information acquiring unit acquires the directional information of the digital photographing apparatus using a geomagnetic sensor,
• wherein the sensor information acquiring unit includes a posture information acquiring unit and the directional information acquiring unit acquires the posture information of the digital photographing apparatus using a tilt sensor.
