Image processing method and image processing device for generating 3d content by means of 2d images

An image processing method performed by an image processing device, the image processing method comprising:

• recognizing a target object in 3D contents;
• obtaining a first image and a second image in which the target object is 2-dimensionally represented;
• detecting a boundary line of the target object in the first image and the second image;
• and
• determining a boundary line three-dimensionally represented in the 3D coordinate system using the detected boundary line.

An image processing device comprising a processor and a memory,

• wherein the processor
• obtains a first image representing a 2D image of 3D contents observed from a first position in a 3D coordinate system,
• obtains a second image representing a 2D image of the 3D contents observed from a second position in the 3D coordinate system,
• detects a first boundary line representing one boundary of the 3D contents from the first image,
• detects a second boundary line representing the one boundary from the second image;
• and
• determines a third boundary line for three-dimensionally representing the one boundary in the 3D coordinate system using the first boundary line and second boundary line.
