Disclosed according to one embodiment of the present invention is a computing device for generating local information of at least one object included in an image. The computing device comprises: a memory comprising computer-executable components; and a processor for executing the computer-executable components, as listed below, stored in the memory, wherein the computer-executable components may include: a keypoint heat map generating component which generates, for the image, a keypoint heat map including keypoint information of the at least one object; a non-rotated bounding box generating component which generates a non-rotated bounding box on the basis of the generated keypoint heat map; a rotated bounding box generating component which generates a rotated bounding box by using the non-rotated bounding box; and a final bounding box generating component which, by using at least one of the rotated bounding box or the non-rotated bounding box, expresses an area occupied by the at least one object within the image.
