Abstract
The method for measuring a distance between vehicles according to the present disclosure includes acquiring a 2D image obtained by capturing a non-ego vehicle using a camera mounted in an ego vehicle in driving, detecting a 2D bounding box which encloses the non-ego vehicle in the 2D image, detecting a 3D coordinate of at least one 3D vertex of a virtual 3D bounding box which encloses the non-ego vehicle in a 3D space, from a coordinate of a vertex of the 2D bounding box, using unprojection conversion from the 2D image to the 3D space, based on an intrinsic parameter of the camera and an extrinsic parameter with respect to the ego vehicle, and measuring a distance between the ego vehicle and the non-ego vehicle using the 3D coordinate of the at least one 3D vertex.
