Method and apparatus for detecting 3D object from 2D image

#Korean Patent Application No. 10-2018-0133044, filed on Nov. 1, 2018, in the Korean Intellectual Property Office, and entitled: “Method and Apparatus for Detecting 3D Object from 2D Image,” is incorporated by reference herein in its entirety.

#Embodiments relate to a method and apparatus for detecting a 3D object from a 2D image.

#Object detection techniques are for detecting a region containing an object from an image. For example, a two-dimensional (2D) bounding box that surrounds an object may be detected from a 2D image using an object detection technique. A 2D bounding box may be specified by the location and size of the 2D bounding box in an image. Object detection techniques may be performed through image processing based on a neural network. In addition, a three-dimensional (3D) bounding box refers to a volume surrounding an object in a 3D coordinate system and may be, e.g., specified by the location, size, and direction of the 3D bounding box in the 3D coordinate system. Applications requiring 3D bounding boxes may include, e.g., driving applications.

#Features will become apparent to those of skill in the art by describing in detail exemplary embodiments with reference to the attached drawings, in which:

#FIG. 1 illustrates a view of an object detection method according to an embodiment;

#FIG. 2 illustrates an operational flowchart of an object detection method according to an embodiment;

#Specific structural or functional descriptions presented in the present specification are example descriptions for describing embodiments according to technical concepts, and the embodiments may be implemented in various other forms without being limited to the forms described in the present specification.

#Although the terms “first” and “second” are used to describe various elements, these terms are only used to distinguish one element from another element. For example, a first element may be referred to a second element, and similarly a second element may be referred to as a first element.

#It should be understood that when an element is referred to as being “coupled” or “connected” to another element, the element may be coupled or connected directly to the other element or any other element may be between the two elements. In contrast, it may be understood that when an element is referred to as being “directly coupled” or “directly connected” to another element, there is no element interposed between the two elements. Expressions used to describe a relationship between elements, e.g., “on,” “directly on,” “between,” “directly between,” “neighboring,” or “directly neighboring” should be interpreted in the same manner.
