Abstract: Provided are a method and a system for generating an AI training hierarchical dataset including data acquisition context information. A GT dataset generation method according to an embodiment of the present disclosure includes: acquiring and storing vehicle data; acquiring and storing sensor data generated at a sensor installed in a vehicle; and generating and storing context information which is information regarding a context at a time when the data is acquired. Accordingly, in generating a GT descriptor, various contexts, conditions at the time when data is acquired may be made to be easily analyzed, classified on the GT descriptor through a hierarchical dataset, which hierarchically describes context information at the time when sensor data is acquired on the descriptor, so that an AI network is effectively trained, and eventually, has high recognition performance.

Abstract: A method and an apparatus for detecting a lane is provided. The lane detection apparatus according to an embodiment includes: an acquisition unit configured to acquire a front image of a vehicle; and a processor configured to input the image acquired through the acquisition unit to an AI model, and to detect information of a lane on a road, and the AI model is trained to detect lane information that is expressed in a plane form from an input image. Accordingly, data imbalance between a lane area and a non-lane area can be solved by using the AI model which learns/predicts lane information that is expressed in a plane form, not in a segment form such as a straight line or curved line.

Abstract: Provided is a method for generating a hollow structure of a 3D model on the basis of a 2D laminated cross-sectional outline to reduce the amount of using a material or the weight of a printed matter during laminating and manufacturing. The method for generating a hollow structure based on a 2D laminated cross-sectional outline, according to an embodiment of the present invention, comprises the steps of: slicing the 3D model; generating a hollow structure outline on the basis of the result of the slicing; detecting an overhang area between adjacent hollow structure outlines; recalculating the hollow structure outline according to the result of detecting the overhang area; and generating a hollow structure mesh on the basis of the recalculated hollow structure outline. Accordingly, because 2D laminated cross-sectional data is used, a hollow structure can be generated without separate data processing, thereby reducing a calculation burden. In addition, because the hollow structure is processed so that an overhang area is not generated when generating the hollow structure, a support is not needed therein, thereby making post-processing easy.
