Apparatus and method for determining rotation angle of object, and computer-readable storage medium storing instructions to perform method for determining rotation angle of object

A method for determining a rotation angle of an object performed by a determining apparatus, the method comprising:

• acquiring an image;
• extracting a first feature point from the image;
• matching the first feature point of the object included in the image with a second feature point of a template by comparing the extracted first feature point with the second feature point within the template in which the second feature point for a predetermined object is previously stored;
• and
• determining the rotation angle of the object included in the image by comparing angle information of the first feature point with angle information of the second feature point.

A non-transitory computer readable storage medium including computer executable instructions, wherein the instructions, when executed by a processor, cause the processor to perform a method for determining a rotation angle of an object, the method comprising:

• acquiring an image;
• extracting a first feature point from the image;
• matching the first feature point of an object included in the image with a second feature point of a template by comparing the extracted first feature point with the second feature point within the template in which the second feature point for a predetermined object is previously stored;
• and
• determining a rotation angle of the object included in the image by comparing angle information of the first feature point with angle information of the second feature point.
